Hydrolysis degree

Tensoactive species obtained by papain hydrolysis of soy protein were characterized structurally and physicochemically, and their foam-forming and -stabilizing capacity studied. Protein structural changes upon reaction ending were correlated with functional and interfacial properties and with the behaviour thereof with varying hydrolysis degree.

Regenerating jute into high-tech nanofibres is an alternative way to use jute fibres. However, dissolving jute has always been a challenge. The complex hierarchal structure of lignin is the main obstacle for hydrolysis of lignocellulosic fibres in obtaining value-added products. This work aims to develop regenerated jute nanofibres through electrospinning. A literature review was conducted to investigate on the methods of regenerating jute for value added products.

The study was carried out to compare types of enzymes and to evaluate effects of conditions for hydrolysis of Tra fish flesh scraps. Among the four experimented enzymes including protamex, papain, neutrase, and alcalase, the last one was the most efficient in term of protein recovery yield and hydrolysis degree.

Genetic variability study of five isolates of Xanthomonas axonopodis pv. citri was carried out using molecular markers. The isolates were collected from five places in Maharashtra state, India. Morphological and Biochemical tests viz. gram’s reaction, starch hydrolysis, indole production, catalase test, KOH test, Gelatin liquefaction and Acid production test were carried out to identify and confirm the purity of the culture.

Shrimp by-product from shrimp processing industry was hydrolyzed by alcalase and flavourzyme and the process was optimized by response surface methodology. Shrimp byproduct was ground and treated with fixed alcalase 0.2 % (4.8A U/kg protein) and flavourzyme of different loadings (0.1 - 0.4 %), pH (6.0 - 9.0), temperature (45 - 65 oC) and hydrolysis time (5 - 1 3 h). At optimal conditions of pH of 7.5, temperature of 59 oC, flavourzyme loadings of 0.4 % (100 LAPU/g protein), alcalase of 0.2 %, and hydrolysis time of 8.2 h, hydrolysis degree was 36.

Collagen thủy phân là hỗn hợp các peptide có phân tử lượng nhỏ hơn 20 kDa được thủy phân từ collagen hoặc gelatin bằng enzyme. Nó có những tính chất và hoạt tính sinh học như khả năng chống oxi hóa, chống đông, kháng khuẩn, ngăn chặn tia cực tím và là chất kích thích cho các hormone làm lành bệnh viêm khớp,... mà collagen và gelatin không có được. Vì vậy, collagen thủy phân được ứng dụng rộng rãi trong công nghiệp thực phẩm, mỹ phẩm và dược phẩm.

Response surface methodology (RSM) was used to determine optimal condition for continuous overflow proteolytic hydrolysis of spent brewer’s yeast. The optimal conditions for obtaining high degree of hydrolysis and low bitterness are determined as followings: ratio of enzyme mixture (alcalase 7.5 U/g and flavourzyme 10 U/g), pH at 7.5, hydrolysis temperature at 51o C and hydrolysis time of 9 hours. Under the optimal conditions, the yield of hydrolysis was 59.62% ± 0.027 and the bitterness equivalently with concentration of quinine was 7.86 ± 0.033 µmol /ml.

Family 18 chitinases such as chitinase B (ChiB) fromSerratia marcescens catalyze glycoside hydrolysis via a mechanism involving the N-acetyl group of the sugar bound to the)1 subsite. We have studied the degradation of the soluble heteropolymer chitosan, to obtain further insight into catalysis in ChiB and to experimentally assess the proposed processive action of this enzyme. Degradation of chitosans with varying degrees of acetylation was monitored by following the size-distribution of oligomers, and oligomers were isolated and partly sequenced using 1 H-NMR spectroscopy....
