Insertion of the T3 DNA polymerase thioredoxin binding domain (TBD) into the distantly related thermostable Taq DNA polymerase at an analogous position in the thumb domain, converts the Taq DNA polymerase from a low processive to a highly processive enzyme. Processivity is dependent on the presence of thioredoxin. The enhancement in processivity is 20-50-fold when compared with the wild-type Ta...

Pectinases are a group of enzymes with broad application, including in plant fiber processing, pectic wastewater treatment, paper pulping, fruit juice extraction, and clarification. With an increasing industrial demand for these enzymes, it is useful to isolate organisms that produce large amounts pectinase possess wide ranges stability factors like temperature pH. In this study, 17 out 29 bact...

glycosyltransferase. the enzyme as a cyclodextrin thermosulfurigenes EM1 and reclassification of alpha-amylase of Thermoanaerobacterium Cyclodextrin formation by the thermostable

A protease producing microorganism was isolated from soil collected from a detergent industry and identified as Bacillus species. Isolate K-30 produced thermostable alkaline protease utilizing rice bran. The optimum conditions for protease activity was 55°C at pH 9 with 4% inoculum in the medium containing 1% rice bran after 96 h of incubation. Beef extract, tryptone and yeast extract were good...

Lignocellulose is the most abundant carbohydrate source in nature and represents an ideal renewable energy source. Thermostable enzymes that hydrolyze lignocellulose to its component sugars have significant advantages for improving the conversion rate of biomass over their mesophilic counterparts. We review here the recent literature on the development and use of thermostable enzymes for the de...

gene (tdh) and the thermostable direct hemolysin-related hemolysingene (blh) of Vibrio parahaemolyticus by polymerase chain reaction. Mol. Cell. Probes, 6, 477-487. 3. Sugiyama, A., Nakano, Y., Iwade, Y., Yamauchi, A., Nakayama, 0., Matsumoto, T., Kou, Y., Ito, T., Nishinaka, T. and Shoji, T. (1 999): Isolation of thermostable direct hemolysin-producing Vibrio parahaemolyticusfrom food implicat...

Selective media for Vibrio parahaemolyticus, BTB-Teepol agar and modified arabinose-ammonium sulfate-cholate agar, were modified for use in immunological detection of the thermostable direct hemolysin produced by this organism. The modified BTB-Teepol agar and modified arabinose-ammonium sulfate-cholate agar were both found to be useful for the modified Elek test and immunohalo test with antise...

Jamun (Syzygium cuminii L.) is one of the important indigenous minor fruit with high medicinal value. The jamun cultivation is unorganized and there is huge loss of this fruit every year. The perishable nature of the fruit makes its postharvest management further difficult. Due to the strong cell wall structure of pectin-protein bonds and hard seeds, extraction of juice becomes difficult. Enzym...

BACKGROUND Ginsenosides are the principal components responsible for the pharmacological activities of ginseng. Ginsenosides Rg1 and Rb1 are the major compounds recognized as marker substances for quality control of ginseng-based products. These major compounds can be transformed to several pharmacologically active minor ginsenosides by chemical, microbial, and enzymatic means. MATERIALS AND ...
