Fermentation of grain in the rumen and the digestion of starch in the small intestine are influenced by both animal and grain characteristics. Two assays were established to determine the importance of grain characteristics on fermentation and enzyme digestion. To simulate microbial fermentation in the rumen finely milled samples of grain were incubated in rumen fluid and the end products of fe...

the aim of this study was evaluation of the effect of controlled fermentation of lactobacillus plantarum on sensory properties and staling of semi-loaf wheat bread. for this purpose, the effect of fermentation times (8, 16, 24 h) and sugar contents (0.5, 1, 1.5%) on activity of mentioned starter in fermentation of wheat flour (with 76% extraction rate) in a split plot design were examined. afte...

pH and fermentable substrates impose selective pressures on gut microbial communities and their metabolisms. We evaluated the relative contributions of pH, alkalinity, and substrate on microbial community structure, metabolism, and functional interactions using triplicate batch cultures started from fecal slurry and incubated with an initial pH of 6.0, 6.5, or 6.9 and 10 mM glucose, fructose, o...

Polyhydroxyalkanoates (PHAs) are a family of biopolyesters synthesized by many types of bacteria as carbon and energy reserve materials. PHAs combine properties of thermal processibility, biodegradability, biocompatibility and sustainability. They have attracted attention from fermentation, materials and biomedical industries. Recent environmental concerns such as CO(2) emissions and plastic po...

Granular and liquid commercial humates, with micronutrients, and a microbial fermentation product were compared in several combinations with nematicides for their effects on cotton lint yield and root-knot nematode suppression. Fumigant nematicides effectively reduced cotton root galling caused by root-knot nematodes, and cotton lint yields increased. Organophosphates and carbamates were not ef...

Pu-erh is a tea produced in Yunnan, China by microbial fermentation of fresh Camellia sinensis leaves by two processes, the traditional raw fermentation and the faster, ripened fermentation. We characterized fungal and bacterial communities in leaves and both Pu-erhs by high-throughput, rDNA-amplicon sequencing and we characterized the profile of bioactive extrolite mycotoxins in Pu-erh teas by...

Succinate is a valuable platform chemical for multiple applications. Confronted with the exhaustion of fossil energy resources, fermentative succinate production from renewable biomass to replace the traditional petrochemical process is receiving an increasing amount of attention. During the past few years, the succinate-producing process using microbial fermentation has been made commercially ...

Brewing beer involves microbial activity at every stage, from raw material production and malting to stability in the package. Most of these activities are desirable, as beer is the result of a traditional food fermentation, but others represent threats to the quality of the final product and must be controlled actively through careful management, the daily task of maltsters and brewers globall...
