screening of3000 soil samples collected from cities of four different provinces of iran for starch-hydrolysing bacteria revealed that the nature is enriched with streptomyces species capable of producing amylolytic enzymes. among the bacterial isolates, one of the high starch-degrading strains was selected for further microbiological identification and also amylolytic enzyme(s) characterization...

The gene encoding the beta-amylase of Bacillus cereus BQ10-S1 (SpoII) was cloned into Escherichia coli JM 109. A sequenced DNA fragment of 2,001 bp contains the beta-amylase gene. The N-terminal sequences (AVNGKG MNPDYKAYLMAPLKKI), the C-terminal sequences (SHTSSW), and the amino acid sequences of the five regions in the beta-amylase molecules were determined. The mature beta-amylase contains 5...

BACKGROUND Starch is one of the most abundant organic polysaccharides available for the production of bio-ethanol as an alternative transport fuel. Cost-effective utilisation of starch requires consolidated bioprocessing (CBP) where a single microorganism can produce the enzymes required for hydrolysis of starch, and also convert the glucose monomers to ethanol. RESULTS The Aspergillus tubing...

Owing to the production of alpha, beta and gamma amylase subtypes; starch degrading microbes, especially bacteria have an invincible role in the food, fermentation, textile and paper industries. Of them, α-amylases from Bacillus spp. have contributed tremendous advancements in bio-industry, especially in starch, detergent and pharmaceutical arena. Though general reviews are seen in literature o...

Of alpha-amylases and other starch-digesting enzymes from bacteria and plants.ess was supplemented with bacterial and fungal amylases or scalded flour. Immunochemical characteristics of alpha-amylase sensitization.Alpha-amylase production and its activity was compared in two different. Bacterial amylases are resistant to high temperatures, they can active in wide pH.fungal amylascs lowest, liqu...

Amylase is one of the earliest characterized enzymes and has many applications in clinical and industrial settings. In biotechnological industries, the amylase activity is enhanced through modifying amylase structure and through cloning and expressing targeted amylases in different species. It is important to understand how engineered amylases can survive from generation to generation. This stu...
