This study aimed to evaluate the potential of commercial enzymes cellulase (CE), xylanase (XY) and the combination of CE + XY to improve rumen fermentation of Guinea grass ecotype ‘A’ (Panicum maximum). The experiment was carried out in a randomized complete block design. In vitro incubations were performed with four doses of individual enzymes and their combinations (1:1 from each enzyme) as 5...
This paper investigates the reduction of acrylamide formation in potato crisps as a result of asparaginase treatment, using calcium chloride and sodium chloride solutions with different concentrations, immersion in different pH solutions, and different frying conditions. The main aim is to compare the reduction of acrylamide in potato crisps using two kinds of asparaginase enzyme; the first enz...
The paper investigates the effects of different commercial carbon and nitrogen sources on the concomitant synthesis of amylase and polygalacturonase enzymes with the aim of optimizing them for maximal enzyme production. The microorganism used in this work was the fungus Trichoderma viride BITRS-1001, which had been previously identified as a highly active producer of amylase and polygalacturona...
Microbial enzymes are often more useful than enzymes derived from plants or animals because of are more stable than their corresponding plant and animal enzymes and their production is more convenient and safer (Wiseman, 1987). Only about 2% of the world’s microorganisms have been tested as enzyme sources. Microbial proteases are degradative enzymes, which catalyze the total hydrolysis of prote...
The deconstruction of biomass is a pivotal process for the manufacture of target products using microbial cells and their enzymes. But the enzymes that possess a significant role in the breakdown of biomass remain relatively unexplored. Thermophilic microorganisms are of special interest as a source of novel thermostable enzymes. Many thermophilic microorganisms possess properties suitable for ...
Background Lignocellulosic biomass is an important resource for renewable production of biofuels and bioproducts. Enzymes that deconstruct this biomass are critical for the viability of biomass-based biofuel production processes. Current commercial enzyme mixtures have limited thermotolerance. Thermophilic fungi may provide enzyme mixtures with greater thermal stability leading to more robust p...
