α-amylases are one of the most common and important industrial enzymes widely used in various industries. The present study was conducted with aim isolating identifying symbiotic α-amylase enzyme-producing bacteria intestine Silago Sihama Rasterliger Canagorta fish living Qeshm Island, Hormozgan. intestinal these species were isolated using nutrient agar culture medium; then, producing screened...

Agricultural resources such as barley, wheat, and corn were hydrolyzed by commercial amylolytic enzymes and fermented into lactic acid by Enterococcus faecalis RKY1. Although no additional nutrients were supplemented to those resources, lactic acid productivities were obtained at >0.8 g/l h from barley and wheat. When 200 g/l of whole wheat flour was hydrolyzed by amylolytic enzymes after the p...

The susceptibility of starch-based biomaterials to enzymatic degradation by amylolytic enzymes (glucoamylase and alpha-amylase) was investigated by means of incubating the materials with a buffer solution, containing enzymes at different concentrations and combinations, at 37 degrees C for 6 weeks. Two polymeric blends of corn starch with poly(ethylene-vinyl alcohol) copolymer and poly(epsilon-...

The usual methods for detecting the action of amylolytic enzymes on starch are confined to three types of measurements: (1) increase in reducing action; (2) decrease in viscosity; and (3) decrease in the color of the resulting dextrin-iodine complex. Optical methods based upon the changes in optical rotation (1) and upon the refractive indices of the individual split-products (2) have been less...

The screening and isolation of fungi producing a cocktail of hydrolytic enzymes was studied. Among the various isolates obtained from different soil samples, a strain NS-2 was selected. The phylogenetic analysis of this strain showed highest homology (99%) with Aspergillus niger. It was capable of producing cellulolytic, hemicellulolytic, amylolytic, and pectinolytic enzymes in appreciable tite...

Generalization of the results theoretical and practical research in production beer showed that rise prices for cereals, particular barley, leads to an increase price malt and, accordingly, cost final product – beer. In this regard, modern brewers face acute problem a shortage high-quality raw materials production, as well high competition consumer market. The need inexpensive brewing has grown...

Bread is one of the most popular mass-consumption products in Russia and world. The improvement bread quality, development new varieties with increased nutritional biological value will improve nutrition patterns population rational way. objective this study to justify use wholemeal spelt flour formulation wheat bread. Generally accepted standard research methods were used. It experimentally pr...
