The purpose of this study was to investigate the feasibility of replacing 40% fish meal in fish diet by solid fermentation of sorghum distillery residue (SDR) with Trametes versicolor LH1 (f-SDR) and to evaluate f-SDR on tilapia anti-heat stress activity. SDR fermented with Trametes versicolor LH1 (f-SDR) increased 9.8% crude protein content and decreased 7.1% crude fiber. The palatability of 40% f-SDR in both small-size (initial mean weight, 270 g) and big-size (initial mean weight, 446 g) size red tilapia (O. niloticus × O. mossambicus) at ambient temperature (25°C) and high temperature (31°C) was the best among the three test feeds (diets containing 14% f-SBM、40% SDR and 40% f-SDR). Percent weight gain (PWG) and specific growth rate (SGR) of big-size red tilapia fed diet containing 40% f-SDR was 3.09% and 0.43% day-1, respectively, higher than the SDR group and the f-SBM group. In-vitro apparent digestibility on dry matter of diet containing 14% f-SBM was 84.32% higher than the SDR group (67.09%) and f-SDR group (53.53%). In-vitro apparent protein digestibility of diet containing 14% f-SBM (86.84%) was significantly (p<0.05) higher than the SDR group (62.81%) and the f-SDR group (67.58%). After hybrid tilapia (O. niloticus × O. aureus) fed the three test feeds for 7 weeks, the feed conversion ratio (FCR) of the f-SBM group (1.10 ± 0.08) and the SDR group (1.16 ± 0.05) were significantly (p<0.05) lower than the f-SDR group (1.30 ± 0.09). Protein efficiency ratio (PER), PWG and SGR were highest in the f-SBM group. After 7 weeks of feeding the three test feeds followed by exposure to 40°C heat stress, the erythrocyte elongation index of the 40% f-SDR group was significantly (p<0.05) lower than the f-SBM group and the SDR group. During heat stress at 40°C, tilapia previously fed diet containing 40% f-SDR showed lower hematocrit, red blood cell counts and hemoglobin concentration than those fed 40% SDR or 14% f-SBM. The concentration of plasma glucose of the 40% f-SDR group was higher than the f-SBM group and the SDR group. Moreover, HSP70 mRNA level in gill and liver of the f-SDR group was significantly (p<0.05) higher than that of the f-SBM group and the SDR group. The hepatosomatic index of the 40% f-SDR group was significantly (p<0.05) higher than the f-SBM group. The survival rate of hybrid tilapia fed diet containing 40% f-SDR (100%) was significantly (p<0.05) higher than the f-SBM group (43.3%) after exposure to 40°C heat stress for 1 hour. Therefore, SDR fermented with Trametes versicolor LH1 could improve the palatability, enhance anti-heat stress tolerance and up-regulate HSP70 expression of tilapia during heat stress.

This study examined the possibility of Trametes versicolor LH1 to reduce the crude fiber content of sorghum distillery residue (SDR) and the feasibility of replacing 20% fish meal in carnivorous fish diet by SDR fermented with T. versicolor LH1 (f-SDR). Submerged fermentation (SmF) and solid-state fermentation (SSF) of T. versicolor LH1 on SDR at 25oC showed a logarithmic growth phase during the first 7 days, followed by slow growth. The mycelium biomass and phytosterol content were the highest after 20 days of SmF fermentation. T. versicolor LH1 had high cellulolytic enzymes activities in SmF being higher than in SSF. SDR cultivated by SmF for 7 days, the crude fiber content reduced from 11.95% to 5.11%, which was lower than that by SSF for 28 days (6.17%). The optimal fermentation to obtain low-fiber f-SDR was obtained by SmF for 7 days. The bioactive compounds including total polyphenols (3093.22 g GAE/g), total flavonoids (122.22 g QE/g dw) and triterpenoids (31.18 g UAE/g dw) were obtained. The antinutritional factors of f-SDR including, phytic acid (130.09 mg /g dw), tannin (0.53 mg CAE/g dw) and trypsin inhibitor (2.27 mg/g dw) still remained. Five dietary feeds were separated into, 20% soybean meal fermented products (f-SBM) as control, 10% f-SDR, 15% f-SDR, 20 % f-SDR and 20% SDR fed grouper (Epinephelus coioides) for 8 weeks. At the end of feeding trail, there was no significant difference in palatability indicated by consuming time, feed utilization rate and specific growth rate between those groupers fed 20% f-SBM and 15% f-SDR groups. Therefore, 15% f-SDR was the optimal ratio of f-SDR to substitute for fish meal. Cold stress was performed at 15oC for 4 h on grouper previously fed diet containing 20% f-SDR showed higher hematocrit, red blood cell counts, hemoglobin concentrations, oxyhemoglobin and higher dissolved oxygen in blood than those fed 20% SDR or 20% f-SBM. The concentration of cortisol and glucose in plasma of the 20% f-SDR group was lower than those fed f-SBM group or SDR. Overall, the crude fiber content of SDR was significantly reduced by SmF for 7 days. Moreover, the reduction of crude fiber content improved the feed palatability and the growth rate, enhance anti-cold stress tolerance of grouper. These findings indicated that low-fiber f-SDR can be developed into functional feed for grouper or other carnivorous fish species.

The purpose of this study was to culture the mycelium of Trametes versicolor LH1 on sorghum distllery residue (SDR) and established the fermented conditions for polypropylene bags. Trametes versicolor LH1 was pre-cultivated with PDA medium, and then cultivated with 10% SDR solution (ℓ) or solid-state SDR medium (S), respectively. Trametes versicolor LH1 was inoculated different inocula size in the SDR polypropylene bag (1kg/package), and then the whiteness and functional components in SDR and all fermented products were compared. SDR bags were inoculated with a bottle of shake flask (ℓ1) and cultured in high ventilation and relative humidity 45% or 85%, respectively. The days of the mycelium grew filled surface of bags were cultivated for 43 days on 45% relative humidity, but shortened to 23 days on 85% relative humidity. In addition, it was inoculated 3 to 5 pieces of SDR medium (S) in bags for 30 days, respectively. On the third day, the appearance of the bags began to show hyphae and the distribution area became larger as the number of inoculated plates increased. Finally, the three fermentation products were all covered with mycelium on 30th days. SDR bags were inoculated with 1 to 3 bottles of shake flask (ℓ1~ℓ3), respectively, only ℓ1 was filled mycelium in surface. The whiteness of ℓ1~ℓ3 and S3~S5 fermented 30 days were about 33.45-38.13 and 39.39-41.44, respectively. The whiteness in all of them was higher than that of SDR (31.04±0.10). The contents of ergosterol and brassicasterol in all fermented products were also higher than that of in SDR. Ergosterol content of ℓ1~ℓ3 and S3~S5 increased by 27.52-33.68% and 117.19-132.08%, respectively. Brassicasterol content of ℓ1~ℓ3 and S3~S5 increased by 56.85%-95.62% and 119.17%-142.06%, respectively. The whiteness and the contents of ergosterol and brassicasterol were also increased significantly in another batch of ℓ1 and S3 cultured 23 days. The whiteness was positively correlated with ergosterol and brassicasterol. The contents of stigmasterol and β-sitosterol were decreased significantly except for ℓ3. Those of them decreased by 18.66-36.64% and 12.47-28.52%, respectively, and were negatively correlated with ergosterol and brassicasterol content. The total polyphenols and total flavonoids contents in the fermentation products were decreased by 54.25-67.63% and 5.74-30.25%, respectively. However, the total polyphenols content decreased by the fermentation products of ℓ1 and S3 for 23 days, which were 36.92% and 56.16%, respectively. Polyphenols might be digested by enzymes such as laccase and polyphenol oxidase from T. versicolor LH1. The policosanols content of S4 and S5 only increased by 25.07 and 26.14%. The content of reducing sugar increased by 43.47-92.07% in all products. There were no significant changes in crude triterpenes. Moreover, the extracellular crude extract from T. versicolor LH1cultured in shake flask to hydrolyze SDR and rice husks. The reducing sugar content increased by 5.38±0.49 g/L and 0.909±0.03 g/L after 48 hours of hydrolysis, respectively. It was confirmed that T. versicolor LH1 has the ability of breaking down cellulose or starch. From above, SDR fermented by T. versicolor LH1, the whiteness and the contents of ergosterol and brassicasterol showed an increasing in fermented products. They are related to the level of fermentation, and can be used as quality control indicators.

This thesis can be divided into four parts. In the first part of this theses, five kinds of commercialized (PY2101, PY2102, PY2103, PY2108, ST010) and one kind of traditional sorghum kojies were used to prepare sorghum liquor. After two times of liquid fermentation and two times of liquid distillation, the yield, turbidity, pH, and sensory preference of the sorghum liquor made using different kojies were compared to select the best koji for the preparation of sorghum liquor. From the view point of fermentation day, yield, and the sensory evaluation result, the koji PY2101 was thought to be the best one for the preparation of the first time distilled sorghum liquor, whereas the koji PY2102 was thought to be the best one for the preparation of the second time distilled sorghum liquor. Based on all the experimental results, the koji PY2102 was thought to be the best koji for the preparation of the liquid fermented and liquid distilled sorghum liquor. In the second part of this theses, volatile compounds in the first and the second time distilled sorghum liquor prepared using the koji PY2102 or the traditional koji were compared. The volatile compounds found in the tested sorghum liquor can be divided into acids, alcohols, esters, aldehydes, ketones, and miscellaneous compounds. More important volatile compounds were found in the sorghum liquor prepared using the koji PY2102 than those sorghum liquor prepared using the traditional koji. More important volatile compounds were found in the second time distilled sorghum liquor prepared using the koji PY2102 than the first time distilled sorghum liquor prepared using the same koji. These results were consistent with the results of the sensory preference. In the third part of this theses, eight kinds of volatile fatty acid combinations, i.e. formic, acetic, propionic, butyric, pentanoic, hexanoic, heptanoic, combined acid A (hexanoic : acetic = 5:3), and combined acid B (hexanoic acid: acetic: butyric = 5:4:3), were added into the fermented sorghum rice inoculated with the koji PY 2102 after three days’ fermentation of the first time fermented sorghum rice. The room temperature and the inner temperature, soluble solid content, specific gravity, and pH of the fermented rice during the first time and the second time fermentation were compared. The fermentation day, the yield, pH, and the sensory evaluation result of the first time and the second time distilled sorghum liquor from the fermented sorghum rice prepared by adding different volatile fatty acid combinations into the first time fermented sorghum rice were compared to select the best acid(s) for the preparation of sorghum liquor. Among the first time distilled sorghum liquor, the liquor prepared with acetic, hexanoic, and combined acid B added in the sorghum rice during the first time fermentation were more preferred than the others. Among the second time distilled sorghum liquor, the liquor prepared with formic, pentanoic, hexanoic, and combined acid B added in the sorghum rice during the first time fermentation were more preferred than the others. In the fourth part of this theses, volatile compounds in the most preferred sorghum liquor of the first time distilled and the second time distilled were compared using solvent extraction and GC-MS. The contribution of the acid(s) added into the first time fermented sorghum rice on the volatile composition of the related first time and the second time distilled sorghum liquor were compared.

In this thesis, 2% butyric acid and 5% caproic acid mix solution was added into the mash in an amount of 0.5 mL per 100 g mash in different time of the fermentation of sorghum mash with an unadded one to be a contrast so as to confer the effects of different acids added time on the flavor an quality.Confusion in addiotn to compare the unadded contrast distilled delicate fragrance sorghum spirits,to compare the delicate fragrance sorghum spirits and different acids added time dense fragrance sorghum spirits which one have better acceptance. The results showed that during the first time fermentation added of 2% butyric acid and 5% caproic acid mix solution will lead pH, temperature of sorghum of mash and the volume of sorghum soirits distilled decreased,the rise range of alcohol content slow down, the decrease range of specific gravity and brix become smaller. In sensory analysis, the distilled sorghum spirits of complex acid-alcohol solution added on the seventh day at the first times’ fermentation had the best acceptance,so we choice it for the best acid added time during first time fermentation. In aroma analysis approve that added caproic acid-butyric acid mixed acid will lead the content of volatility alcohol,aldehyde and ester to descend,the content of acid rise up. In the composition of volatile compounds we can saw that acid added on the fifth day at the first times’ fermentation will lead volatility acid and fusel occupy to go across high percentage,ester occupy to go across low, effect the acceptance, but the effect of acid added at seventh and ninth day will smaller. During the second time fermentation added of butyric acid-caproic acid complex acid will also lead pH, temperature of sorghum of mash and the volume of sorghum soirits distilled decreased,the rise range of alcohol content slow down, the decrease range of specific gravity and brix become smaller. No matter the sorghum mash added acid or not during the first time fermentation will also have the same condition during the second time fermentation. In sensory analysis, the second time distilled sorghum spirits of complex acid-alcohol solution added on the fourth day at the second times’ fermentation had the best acceptance,so we choice it for the best acid added time during second time fermentation. In the composition of volatile compounds we can saw that acid added on the second day at the second times’ fermentation will lead volatility acid and fusel occupy to go across high percentage,ester occupy to go across low, effect the acceptance, but the effect of acid added at fourth and sixth day will smaller. In the content and the composition of volatile compounds in second distilled and redistilled sorghum spirits we can saw that the content of volatile compounds in redistilled sorghum spirits to arrange 50~60% of the second sorghum spirits,but the composition is to approach.

Sorghum distillery residue (SDR) fermented with Trametes versicolor (f-SDR) contains various functional compounds that can be used for anti-cold stress of fish. Previously f-SDR was fermented with 30 g SDR in petri dish (f-SDR-30). The optimal pH of f-SDR cultivation was found to be pH 6.5, while optimal temperature was not studied. In this study, Trametes versicolor LH1 was fermented in SDR at pH 6.5 and 20℃, 25℃, 30℃. Best growth of f-SDR in petri dish was at pH 6.5 and 25℃ for 7 days. The scale-up cultivation of f-SDR at optimal condition was tested in steel trays each of which contained 500 g (f-SDR-500) and 1000 g (f-SDR-1000). The appearance, whiteness, functional compounds of f-SDR-30, f-SDR-500, f-SDR-1000 and nano-f-SDR (n-f-SDR) showed no difference, but n-f-SDR showed less whiteness than f-SDR. The functional compounds, including total polyphenols, total flavonoids, tannins, total triterpenoids, phenolic acids, β-glucan, glycopeptide and monosaccharide compositions, phytosterols and policosanols contents of f-SDR-30, f-SDR-500 and f-SDR-1000 showed no significant (p>0.05) difference. All functional compound contents in n-f-SDR except phenolic acids were higher than SDR, f-SDR-30, f-SDR-500 and f-SDR-1000. Furthermore, in the plasma of cobia fed f-SDR showed higher total antioxidant status than those fed control diet for 28 days. The water quality measured after cobia fed control and f-SDR diet for 41 days followed by cold stress, water temperature (16.5℃), pH (7.77~7.85) and salinity (3.6%) showing no significant (p>0.05) difference, but total ammonium and suspended solids in water of cobia fed control diet were 8.08 ppm and 4.00 mg/L TSS respectively, being significantly (p<0.05) higher than that of cobia fed f-SDR diet (1.25 ppm; 2.00mg/L TSS). Moreover, in the plasma of cobia fed f-SDR diet showed higher total antioxidant status, lysozyme activity and glucose concentration but lower total cholesterol than those fed control diet followed by cold stress, the juvenile cobia has the same result.
