The amylolytic and related enzymes have been classified into the families of glycoside hydrolases (GHs). At present there are almost one hundred GH families. The main α-amylase family is the family GH-13 that forms the clan GH-H together with the families GH-70 and GH-77. β-Amylases and glucoamylases have their own families GH-14 and GH15, respectively. Some amylolytic enzymes are grouped also ...

the cotton bollworm, helicoverpa armigera (hübner), is a serious pest on a wide range of economic crops in many parts of the world. in this study, digestive proteolytic and amylolytic activities of h. armigera larvae (3rd to 5th instars) were evaluated on five main host plants including chickpea (cv hashem), cowpea (cv mashhad), soybean (cv 033), navybean (cv dehghan), and corn (cv sc 704) at 2...

Anaerobranca gottschalkii strain LBS3 T is an extremophile living at high temperature (up to 65 degrees C) and in alkaline environments (up to pH 10.5). An assembly of 696 DNA contigs representing about 96% of the 2.26-Mbp genome of A. gottschalkii has been generated with a low-sequence-coverage shotgun-sequencing strategy. The chosen sequencing strategy provided rapid and economical access to ...

This work aimed at investigating the simultaneous production of amylases and proteases by solid-state fermentation (SSF) of babassu cake using Aspergillus awamori IOC-3914. By means of experimental design techniques and the desirability function, optimum inoculum conditions (C/N ratio of propagation medium, inoculum age, and concentration of inoculum added to SSF medium) for the production of b...

Abstract The paper presents studies of the enzymatic activity barley grains different varieties. In experiments with varieties malting barley, isoforms amylolytic enzymes was determined at pH = 5.5, 7.0, 8.0 using a phosphate buffer system (1/15 M buffer). in germinated grain after removal sprouts and roots. to determine amylases study action acidic (pH 5.5), neutral 7) alkaline 8) environments...

The Neisseria polysaccharea gene encoding amylosucrase was subcloned and expressed in Escherichia coli. Sequencing revealed that the deduced amino acid sequence differs significantly from that previously published. Comparison of the sequence with that of enzymes of the alpha-amylase family predicted a (beta/alpha)8-barrel domain. Six of the eight highly conserved regions in amylolytic enzymes a...

Isolated Bacillus strains BA1 and BA2 were a good source of amylase as they also showed high amylolytic activity. Both showed a clear zone on starch agar plate of 4.0 & 4.2mm in diameter respectively. The strain BA1 and BA2 produce amount of amylolytic enzyme 0.908μ/ml and 0.802μ/ml after the incubation of 24 hours at 37±2 0 C respectively. As the time of incubation increase the amylolytic acti...
