Many countries have been devoted to study biofuels for the substitution of fossil fuels. Studies were mainly concentrated and focused on studying the biodiesel and the oil-producing algae. The aim of this study is to find the optimal culture conditions of fresh water green algae (Chlorella protothecoides, C. vulgaris, Ourococcus sp., Scenedesmus obliquus, and S. dimorphus) in view of their possible utilization as novel feedstock for biodiesel production. At the same time, the Nile red method is used to quantify the lipid content in the oil-producing algae. The results showed the optimal culture conditions for C. protothecoides, Ourococcus sp. and S. dimorphus were at an air flow rate of 1.0 L/L.min, light intensity of 95 μmol/m2s (7000 Lux) and a continuous light cycle (light: dark, 24:0, h). The optimal culture conditions for S. obliquus and C. vulgaris were similar to what mentioned above, the only difference for S. obliquus was the light intensity of 143 μmol/m2s (10500 Lux); and the air flow rate was 2.0 L/L.min for C. vulgaris. Under the optimal culture conditions, algae growth rate were 1.8 - 3.1 times fast than statically cultured, with 2.2 - 4.4 days of reduction in generation time, and an increase of 1.6 - 8.2 times biomass.After seven day-cultured in optimal condition, the lipid in algae ranged from 28.5% to 42.7% (w/w) by Nile red method and from 14.5% to 36.2% (w/w) by gravimetric method. These results revealed that neutral lipid content determined by Nile red method was higher than that by gravimetric method. Additionally, Nile red method was more efficient to perform than gravimetric method. Therefore, the gravimetric method was used to determine lipid content of five algae and S. dimorphus had the highest lipid yield, which may make it an ideal source of biodiesel.

Повний текст джерелаAlgae as a potentially sustainable source of fuel, feed and nutraceuticals has led to interest in the algae biorefinery concept for production of sustainable products. The cultivation of algae has several advantages as algae can grow in non-potable water and in non-arable land and can sequester CO₂ from flue gas. In addition, different components of the algae produce different value-added products such as biodiesel, which is obtained from TAGs, bioethanol from starch and animal feed from functional biomass. However, there is a lack of commercial viability for photosynthetic algae due to limitations in biomass productivity and the capacity to optimise the chemical composition of the algae, both of which are caused by suboptimal nutrient loading and low light conditions. Therefore, this thesis aims to understand how to optimise the production of the individual biochemical algae components, namely, starch, TAGs and functional biomass by modelling batch photosynthetic cultures. Special attention was given to the influence of external nitrogen and light conditions on composition kinetics. The primary species studied in this thesis is Chlorella vulgaris for varying nitrogen load and Scenedesmus obliquus for varying light flux. Biochemical measurements on S. Obliquus for different light conditions were reported and compared with the simulation model. Finally, trial experiments on the effect of glucose relative to a photosynthetic control on algal growth were also performed on Nannochloropsis oculata and Tetraselmis Chuii. A review of algal composition modelling was carried out to assess the current gap in modelling functional biomass, starch and TAGs/lipids as a function of light and extracellular nitrogen. It was found that batch and fed batch studies simulated the algae as being composed of only two fractions, lipids and functional biomass. However, the starch fraction was omitted in most published work, although it is a major component of algae and possesses different kinetic behaviour from lipids and functional biomass. Nevertheless, there were some studies of continuous cultures on starch, TAGs and functional biomass, but to date there are no batch mode studies on photosynthetic cultures that model starch, TAGs and functional biomass simultaneously. A mathematical model of starch, TAGs and functional biomass kinetics of C. vulgaris was developed to elucidate the primary mechanisms of photosynthetic kinetics. This was achieved by explicitly modelling starch, TAGs and functional biomass fractions for a batch photosynthetic reactor. In addition, TAGs production due to starch glycolysis was also considered in the model. This biochemical pathway has not been previously modelled in the literature. The model was composed of six coupled ordinary differential equations and 11 secondary equations and was coded and solved in Matlab. The parameters were tuned by minimising an objective function, which was the overall relative error of the model. There were 15-17 biological fitting parameters in the model depending on the limiting conditions affecting starch glycolysis. Four sets of limiting conditions were identified for modelling starch glycolysis and TAGs synthesis from photosynthesis. The first study carried out was the analysis of the influence of extracellular nitrogen on composition kinetics. The nitrogen quota and light dependant photosynthetic activity were found to be primary regulators for starch-TAG kinetics in C. Vulgaris. In contrast metabolite saturation, C-N uptake ratio and starch concentration did not have a significant impact on composition kinetics. Once the influence of nitrogen concentration was investigated, the following step was to test if starch glycolysis was dictating composition kinetics under the influence of moderate to high light intensities. In order to model the influence of carbon uptake for different light fluxes, an exponential decay function, in contrast to the Poisson’s single hit model used in the previous chapter for C. vulgaris, was utilised. The species that was modelled was S. obliquus and the light intensities tested were 200 µmols/m².s and 1000 µmols/m².s. The selection of these conditions was due to the existence of experimental literature values that allowed the validation of the model. The model predicted the experimental data with an average percentage error of 10 % for 200 µmols/m².s and 17 % for 1000 µmols/m².s. The only discrepancy between the model and experiment was for starch concentration for 1000 µmols/m².s light intensity. The origin of this discrepancy was attributed to not accounting for metabolite catabolism of TAGs. This occurred at high light intensities because the culture may have reached a point in its growth phase, where substrate catabolism began. Experimental work was carried out to investigate the composition of S. obliquus for different nitrogen concentration and light conditions. The starch, TAGs, protein and chlorophyll contents were in good agreement with literature values and batch culture model predictions. This agreement between modelling and experiments was arguably attributed to the fact that nitrogen quota, which dictates starch, TAGs and protein kinetics, is independent of reactor running mode, i.e., batch or continuous. Preliminary experiments for mixotrophic algae were conducted at The Port Stephens Fisheries Institute (PSFI) to assess whether mixotrophic cultivation of green algae could improve yields relative to a photosynthetic control. The species that were investigated included N. oculata and T. Chuii. During the first 7 days of growth, cell densities for mixotrophic and phototrophic algae were similar. After this initial period, cell densities of mixotrophic algae were half the density of the photosynthetic culture. Bacterial contamination was the primary reason for a lack of improvement in cell density. It was hypothesised in this thesis that starch glycolysis linked starch degradation to TAGs accumulation during nitrogen depletion. This hypothesis was tested for two different species, C. vulgaris and S. obliquus for different nitrogen and light levels. It was found that starch glycolysis could explain the kinetic behaviour of algae during nitrogen depletion and light intensities in the light limited and saturated region for batch photosynthetic studies. Currently, this has not been reported in literature models. Future studies may attempt to validate this model for species other than green algae or for different growth modes such as heterotrophy or mixotrophy using acetate as a carbon source due to its ability to inhibit bacterial growth.

This study isolated Ulva fasciata Delile filaments for algal "seed stock" and mass culture by using those filaments hanging in the land culture tank. The attached seedlings could be repeated harvesting that was the benefit feature of cotton rope hanging cultivation, which could reduce the seedlings and culture time. During the 192 d of cultivation, had harvested total 3880.0 g wet weight and 540.9 g dry weight of the alga. The average growth rate was 3.82 ± 1.61%, and the average biomass was 3.54 ± 0.81 g•m-1day-1. The average growth per 1 g of wet weight alga absorbed 22.42 ± 2.54 g CO₂, the average growth per 1 g of dry weight alga absorbed 157.77 ± 20.59 g CO₂, the average production per unit area was 1743.77 g•m-2 month-1, and the average amount of CO₂ absorption per unit area was 44820 ± 10330 g•m-2 month-1. U. fasciata filaments when cultured under low light 50-100 μmol photons•m-2•s-1, it did not differentiate, but when cultured under light 160-180 μmol photons•m-2•s-1, it grew to form tubular thalli, and then cultured under light 250 μmol photons•m-2•s-1,the tubular thalli transformed into thallus thalli. The filaments could be a "seed stock" of U. fasciata for mass cultivation, and they could also be immobilized by sodium alginate and with PVA embedment technology for long-term storage.

As an island county, algal resources are abundant in Penghu islands. However, the majority of algal productivity is based on wild harvesting seaweeds, Monostroma nitidum and Porphyra dentate in the winter. A small scale of aquaculture of P. dentate only occurs in Jiangmei area, but the productivity is remarkably affected by the weather condition . There are nine species of Caulerpa commonly found in Penghu; however, the studies of Caulerpa were focused on taxonomy, not aquaculture. In addition, epiphytic fauna in association with Caulerpa also increase the difficulties of algal farming and reduces the commercial value of Caulerpa. In this study, a market-valued species, C. lentillifera, was selected for aquaculture experiments under different treatments of temperature, salinity, and lighting resource. Methods of epibiotic fauna removal using fresh water, Gram’s Iodine, and acid solution were examined. The optimal culturing temperature for C. lentillifera was ranged in 30 ~ 32 ℃ (0.58 ± 0.21 % day-1). The optimal culturing salinity ranged in 33 ~ 36 psu (0.69 ± 0.52 % day-1). The optimal culturing light intensity ranged in 25 ~ 30 μ mol photon m-2s-1 (1.26 ± 0.16 % day-1). In Penghu, the most commond epiphytic fauna in association with Caulerpa are sea anemone, Aiptasia pulchella, isopod, Tylos minor, and amphipod, Orchestia platensis. The removal rates of A. pulchella, T. minor, and O. platensis on the algae immersed in fresh water for 60 minutes were 46.6 ± 3.2 %, 100 %, and 100 %, respectively. The removal rates of A. pulchella, T. minor, and O. platensis on the algae immersed in 1.5 % Gram’s Iodine solution for 120 minutes were 30.0 ± 10.0 %, 83.3 ± 15.3 %, and 63.3 ± 5.8 %, respectively. The removal rates of A. pulchella, T. minor, and O. platensis on the algae immersed in 10 % vinegar-seawater for 40 minutes were 77.1 ± 21.3 %, 100 %, and 100 %, respectively. The combination of the treatments applied to the algae is likely to maximize removal rate.
