Resumo: Transglutaminase é uma enzima capaz de catalisar a formação de ligações cruzadas intra- e intermoleculares entre proteínas, peptídeos e aminas primárias por meio de ligações covalentes entre resíduos de lisina e glutamina. Desta forma, transglutaminase pode ser utilizada em diversos setores industriais para o desenvolvimento de novos produtos ou para a modificação de suas características. A linhagem B6 isolada de amostra de solo coletada na região do Estado de Minas Gerais foi identificada como tendo características morfológicas típicas de actinomicetos e pela análise da região 16S rRNA há colocou na subclasse Streptomyces próximo a linhagem Streptomyces angustmycinicus NBRC 3934T. A fim de aumentar a produção de transglutaminase (2,75 U/mL) pela linhagem Streptomyces sp. B6, o meio de fermentação foi submetido a processos de otimização. Como primeiro passo da otimização, o crescimento do micro-organismo e a produção da enzima foram estudados através de uma pré-seleção de fontes de carbono, nitrogênio e sais no meio de produção. Após as análises das diferentes fontes, um delineamento experimental do tipo Plackett-Burman foi utilizado para a seleção dos componentes do meio de cultivo que afetam a produção de transglutaminase. Os resultados do delineamento experimental indicaram que a produção de transglutaminase foi influenciada negativamente pela peptona bacteriológica e MgSO4.7H2O, positivamente pelo amido de batata, glicose, peptona de caseína e KH2PO4.7H2O e não foi influenciada pelo farelo de soja, considerando um nível de confiança de 95%. A concentração de amido de batata foi fixada no maior nível testado no planejamento Plackett-Burman devido à gelificação do meio de fermentação em concentrações maiores. Assim, os três fatores que influenciaram a produção de transglutaminase (glicose, peptona de caseína e KH2PO4.7H2O) foram otimizados para obter o máximo de produção da enzima utilizando delineamento composto central. Sob a condição otimizada, a qual continha 25 g/L de farinha de soja, 35 g/L de amido de batata, 5 g/L de glicose, 24,5 g/L de peptona de caseína e 8 g/L de KH2PO4.7H2O, a atividade enzimática atingiu 6,13 U/mL, apresentando 125% à mais de atividade em relação á obtida no meio antes da otimização. A transglutaminase microbiana produzida pela linhagem Streptomyces sp. B6 exibiu atividade ótima em 45°C e em pH de 6,5 e 11,0. A enzima manteve-se estável na faixa de pH 3,0-11,0 durante 60 minutos à 40°C durante 3 horas. A transglutaminase não foi inibida por Ca2+, Na+, Co2+, Mn2+, K+, Mg2+, Ba2+, EDTA, L-cisteína e glutationa na concentração de 5 mM, mas foi inibida na presença de Hg2+, Cu2+, Zn2+ e Fe2+ na concentração de 5mM. A linhagem Streptomyces sp. B6 é uma nova fonte de transglutaminase com características interessantes para aplicações biotecnológicas
Abstract: Transglutaminase is an enzyme capable of catalyzing the forming intra-and intermolecular cross-linking between proteins, peptides and primary amines by covalent bonds between lysine and glutamine residues. Thus, transglutaminase can be used in food processing industries to develop new products and modify their characteristics. The B6 strain was isolated from soil sample collected in the region state of Minas Gerais was identified as having morphological characteristics typical of the actinomycetes, and the 16S rRNA analysis placed it in the Streptomyces subclade, closely related to Streptomyces angustmycinicus NBRC 3934T. In order to increase the transglutaminase production (2.75 U/mL) from Streptomyces sp. B6 strain, the fermentation medium was subjected to optimization processes. In the first step of optimization, the micro-organism growth and enzyme production were studied through a pre-selection of carbon, nitrogen and salts sources in the culture medium. After analysis of different sources, the Plackett¿Burman experimental design was used for screening the components of the culture medium that affect the transglutaminase production. Results of the experiment indicated that production of transglutaminase was negatively influenced by bacteriological peptone and MgSO4.7H2O, positively influenced by potato starch, glucose, casein peptone and KH2PO4.7H2O and was not influenced by soybean meal, considering 95% of confidence level. The potato starch concentration was fixed at the highest level tested in Plackett¿Burman design due to gelation of the fermentation medium in higher concentrations. Thus, the three factors that influence the transglutaminase production (glucose, casein peptone and KH2PO4.7H2O concentrations) were optimized to obtain the maximum transglutaminase production using central composite design. Under the proposed optimized condition, which contained 25 g/L soybean meal, 35 g/L potato starch, 5 g/L glucose, 24.5 g/L casein peptone and 8 g/L KH2PO4.7H2O, the enzyme activity reached 6.13 U/mL, which was 125% more than the activity in relative obtained medium before optimization. The microbial transglutaminase produced by Streptomyces sp. B6 strain exhibited optimal activity at 45 oC and at pH 6.5 and 11.0. The enzyme remained stable in the pH range from 3.0 - 11.0 for 60 minutes and at 40 oC temperature for 3 hours. The transglutaminase was not inhibited by Ca2+, Na+, Co2+, Mn2+, K+, Mg2+, Ba2+, EDTA, L-cysteine and glutathione in concentration 5 mM, but was inhibited in the presence of Hg2+, Cu2+, Zn2+ and Fe2+ in concentration 5 mM. In conclusion, Streptomyces sp. B6 strain is a new source of transglutaminase with interesting features for biotechnological applications

Soil is complicated, both in terms of its physical makeup and the organisms that live inside of it. Predicting changes in soil based on the addition of foreign material such as chemicals or biological waste is not an easy process, and whether or not it is even possible to reliably predict those changes is a matter of some dispute. This study is designed to illustrate that such changes can in fact be reliably and consistently predicted even with regard to the addition of complicated materials to the soil. In this study, specifically, the material in question is chicken litter. A mix of the bedding and waste produced by chickens, litter is commonly handled by composting and is added to soil in farms as a fertilizer rich in organic matter. It is possible to point at specific elements of the soil such as the chemistry and bacteria and see how it is changed with the addition of chicken litter, which allows us to determine the nature and extent of the change that chicken litter has on soil. This study is conducted on a larger scale than similar experiments conducted in the past, making it apparent that these relationships exist on a repeated basis. It is the object of this study to pave the way and make it easier for scientists in the future to determine these relationships in other unique contexts.

Resumo: A transglutaminase (TGase) (EC 2.3.2.13; proteina-glutamina ?-glutaminiltransferase) é uma enzima capaz de catalisar reações de transferência de grupos acil utilizando resíduos de glutamina das ligações peptídicas de proteínas como doadores de grupos acil, e diversas aminas primárias como receptores. As ligações covalentes cruzadas entre inúmeras proteínas e peptídeos pela transglutaminase promovem mudanças nas propriedades de proteínas de alimentos. Por essa razão, a transglutaminase é amplamente utilizada nas indústrias de processamento de alimentos para o desenvolvimento de novos produtos e modificação de características como: viscosidade, capacidade emulsificante e valores nutricionais. Uma cepa de Actinomyceto, isolada de amostras de solo brasileiro, foi investigada taxonomicamente por uma combinação de técnicas moleculares e morfológicas, resultando na conclusão de que a cepa pertence ao gênero Streptomyces sp. A cepa, chamada de Streptomyces sp. CBMAI 837 produziu transglutaminase quando cultivada a 30°C por cinco dias, em agitador rotatório, no meio de fermentação otimizado, composto por: 0,2% KH2PO4, 0,1% MgSO4.7H2O, 2% farinha de soja, 2% amido de batata, 0,2% glicose, e 2% peptona, atingindo uma atividade enzimática de 1,37 U.mL-1. A transglutaminase foi purificada cerca de 5 vezes através de duas passagens cromatográficas sucessivas em uma coluna de filtração em gel Sephadex G-75, com 17% de recuperação. A purificação da proteína foi comprovada por homogeneidade eletroforética em SDS-PAGE. A massa molar da TGase foi estimada em cerca de 45 kDa. A transglutaminase de Streptomyces sp CBMAI 837, tanto na forma bruta quanto purificada, apresentou atividade enzimática ótima em pH 6,0-6,5, e em 35-40°C. Um segundo pico de atividade ótima foi observado em pH 10,0 na enzima no estado bruto. Ambas as formas da enzima foram estáveis na faixa de pH de 4,5 a 8,0 e até 45°C. A transglutaminase na forma bruta e purificada mostrou-se independente de íons cálcio, mas foi ativada na presença de K+, Ba2+, e Co2+; e inibida por Cu2+ e Hg2; o que sugere a presença de um grupo tiol no sítio ativo da enzima. A TGase purificada apresentou um Km de 6,37 mM e um Vmax de 1,70 U/mL, enquanto a enzima bruta apresentou Km de 6,52 mM e um Vmax de 1,35 U/mL para o substrato N-carbobenzoxi-L-glutaminil-glicina. A influência da transglutaminase de Streptomyces sp CBMAI 837 bruta, nas propriedades de géis ácidos de caseinato de sódio foi investigada, tendo como parâmetro géis preparados com a TGase comercial (Ajinomoto Inc.). Os géis com a enzima comercial tiveram um valor de módulo de elasticidade maior, porém, dependendo da concentração de proteína, estes foram menos deformáveis. Os géis com enzima bruta de Streptomyces sp. CBMAI 837 se mostraram muito mais rígidos e menos elásticos. Resultados da eletroforese indicaram que a enzima comercial promoveu a formação de polímeros de proteínas de massa molecular mais alta do que a enzima de Streptomyces sp. CBMAI 837. Os testes de microscopia eletrônica de varredura e da capacidade de retenção de água mostraram que características particulares de cada um dos géis poderiam estar associadas ao tipo específico de interação promovida por cada uma das amostras enzimáticas testadas
Abstract: Transglutaminase (EC 2.3.2.13; protein-glutamine ?-glutaminyltransferase) is an enzyme that catalysis an acyl transfer reaction using protein or peptide-bond glutamine residues as acyl donors and several primary amines as receptors. The covalent cross-links between a number of proteins and peptides introduced by transglutaminase promote modification of the functional properties of the food proteins. Therefore, transglutaminase are widely used by food-processing industries for the purpose of new product development, modification of the product properties such as viscosity, emulsification foaming and nutritional values. An actinomycete strain, isolated from Brazilian soil, was taxonomically investigated using a combination of molecular and morphological basedmethods, resulting on the conclusion that the strain belongs to the genus Streptomyces sp. The strain, named Streptomyces sp. CBMAI 837, produce transglutaminase when cultivated at 30°C for 5 days at 200 rpm in a rotatory shaker, on the optimized fermentation medium composed of 0.2% KH2PO4, 0.1% MgSO4.7H2O, 2% soybean flour, 2% potato starch, 0.2% glucose, and 2% peptone, with a enzymatic activity of 1.37 U.mL-1. The enzyme purification was performed by of two successive chromatographies on Sephadex G-75 columns with yields of 48% and 17%, respectively. The protein purification was successfully achieved to electrophoretical homogeneity on SDS-PAGE. The molecular mass of the MTGase was estimated to be about 45 kDa. The enzyme from Streptomyces sp., in both crude and pure forms, exhibited optimal activity in the 6.0-6.5 pH range and at 35-40°C. A second maximum of activity was observed at pH 10.0 on the crude Streptomyces sp. enzyme. Both forms of transglutaminase were stable over the pH range from 4.5 to 8.0 and up to 45°C. The activities of all the TGase samples were independent of Ca+2 concentration, but they were elevated in the presence of K+, Ba2+, and Co2+ and inhibited by Cu2+ and Hg2+, which suggests the presence of a thiol group in the TGase¿s active site. The purified enzyme presented Km of 6.37 mM and Vmax of 1.7 U/mL, while the crude enzyme demonstrated Km of 6.52 mM and Vmax of 1.35 U/mL. The influence of the transglutaminase on acid-gel properties was studied. Texture parameters showed that the commercial TGase (Ajinomoto Inc.) gels had greater values of elasticity modulus and could promote the formation of more elastic and soft food systems, while addition of the crude TGase of Streptomyces sp. CBMAI 837 to the gel led to the formation of more rigid and less elastic gels. The electrophoresis showed that the commercial TG enzyme in this system promoted higher molecular mass protein polymers than the enzyme from Streptomyces sp. CBMAI 837. Microscopy and water holding capacity (WHC) observations showed that all the gel characteristics could be associated to specific interactions promoted by each TGase tested
