Thermophilic bacteria have gained increased attention as candidates for bioethanol production from lignocellulosic biomass. This study investigated ethanol production by Thermoanaerobacter strain J1 from hydrolysates made from lignocellulosic biomass in batch cultures. The effect of increased initial glucose concentration and the partial pressure of hydrogen on end product formation were examin...

BACKGROUND Microbial conversion of lignocellulosic feedstocks into biofuels remains an attractive means to produce sustainable energy. It is essential to produce lignocellulosic hydrolysates in a consistent manner in order to study microbial performance in different feedstock hydrolysates. Because of the potential to introduce microbial contamination from the untreated biomass or at various poi...

Currently, there is an urgent need for domestic fermentation activators based on low-cost secondary raw materials. We aimed to study the effect of microbial enzyme preparations with different action hydrolysis proteins and phytin grain bran obtain that could become alternative imported ones.
 studied wheat rye brans; cytolytic, proteolytic, phytase action; multi-enzyme compositions; hydrol...

Poultry by-products and rainbow trout (Onchorhynchus mykiss) viscera are abundant and underutilized resources that can be used as a unique protein source to make protein hydrolysates. In this study protein hydrolysate were made from these two different sources with Alcalase 2.4L. The functional properties of Fish viscera protein hydrolysate (FPH) compared to poultry by-products protein hydrolys...

BACKGROUND Hair is composed mainly of keratin protein and a small amount of lipid. Protein hydrolysates, in particular those with low molecular weight distribution have been known to protect hair against chemical and environmental damage. Many types of protein hydrolysates from plants and animals have been used in hair and personal care such as keratin hydrolysates obtained from nails, horns an...

Abstract This study aimed to investigate the anti-obesity potential of camel colostrum and milk proteins as well their enzymatic hydrolysates. Camel were treated using six proteolytic enzymes (pepsin, trypsin, α-chymotrypsin, pancreatin, papain, pronase). The degree hydrolysis was measured verify degradation proteins. in vitro activity evaluated pancreatic lipase inhibitory assay. protein hydro...

Background Hydrolysates are complex media supplements composed of many as well as different types of compounds. Within Frieslandcampina Domo’s Quality by Design project, detailed information of these compounds (annotation and quantification) has been generated. This was achieved for soy protein hydrolysates (Proyield Soy SE50MAF-UF) using metabolomics biochemical profiling. Biochemical profilin...

Polysaccharides extracted from cell walls of 4 serological types of Group D streptococci were serologically type-specific. Acid hydrolysates of all 4 contained hexosamine (glucosamine), rhamnose and glucose. A polysaccharide extracted from 2 serological types by either alkaline treatment or mechanical disruption was serologically group-specific. Acid hydrolysates contained glucose and no other ...

A compound stimulatory to the growth of Lactobacillus casei was isolated from cell extracts of Streptococcus lactis, purified, and characterized. The stimulant was identified as a small peptide with a molecular weight of approximately 4,500 daltons. The purified peptide gave negative tests for nucleic acids, phosphorus, glucosamine, and carbohydrates. Sixteen amino acids were detected in acid h...

Hydrolysates of cod viscera were tested as an alternative to commonly used complex nitrogen sources (peptones and/or extracts) for the type strains of the lactic acid bacteria Lactococcus lactis, Lactobacillus acidophilus, Lactobacillus helveticus, Lactobacillus casei, Lactobacillus sakei and Pediococcus pentosaceus. Comparative studies with MRS-like media containing different nitrogen sources ...
