A manganese peroxidase gene (mnp1) from Phanerochaete chrysosporium was efficiently expressed in Aspergillus oryzae. Expression was achieved by fusing the mature cDNA of mnp1 with the A. oryzae Taka amylase promoter and secretion signal. The 3' untranslated region of the glucoamylase gene of Aspergillus awamori provided the terminator. The recombinant protein (rMnP) was secreted in an active fo...

Six previously constructed and nine newly constructed Aspergillus awamori glucoamylases with multiple mutations made by combining existing single mutations were tested for their ability to produce glucose from maltodextrins. Multiple mutations have cumulative effects on glucose yield, specific activity and thermostability. No general correlation between glucose yield and thermostability was obs...

Heterologous products are frequent applications of microbial technology. Depending on the product, the host-vector system has to be chosen in order to fulfill process requirements. This short review summarizes published and unpublished results obtained for the production of heterologous metabolites and proteins from a single host, the yeast Kluyveromyces lactis, and by means of tools – promoter...

Cereal Chem. 82(5):554-558 Field peas (Pisum salivum) were evaluated as a potential feedstock for ethanol production. Ground peas were dry-milled and separated into starch, protein, and fibrous fractions by air classification. Starch-enriched fractions prepared from whole peas and dehulled peas contained 73.717c wt and 77.8% wt starch, respectively, a nearly two-fold enrichment compared with wh...

Inhibition of maltase, sucrase, isomaltase and glucoamylase activity by acarbose, epigallocatechin gallate, epicatechin gallate four polyphenol-rich tea extract from white, green, oolong, black tea, were investigated using rat intestinal enzymes human Caco-2 cells. Regarding enzyme mixture, all extracts very effective in inhibiting maltase activity, but only white inhibited sucrase the inhibiti...

The search for alternative ingredients as natural sweeteners needs to be done. circulating in the market are synthetic with no nutritional value and harm health. This research aims produce a safe sweetener form of glucose syrup, which can used an artificial through enzymatic reactions, find out suitable reaction conditions syrup highest levels several combinations pH temperature. Mango seed cor...
