Aerobacter aerogenes, Paracolobactrum aerogenoides, Spirillum serpens, and gelatinous strains of Chromobacterium violaceum produced an extracellular, ether-soluble, Ehrlich-positive substance when grown in media prepared with gelatin hydrolysate. The substance has been tentatively identified as pyrrole-2-carboxylic acid. Both hydroxy-l-proline and allo-d-hydroxyproline have been shown to be pre...

The alkaline fractionation of rice husk (RH) with NaOH was optimized for the purpose obtaining a high-yield recovery glucan and increasing removal rate lignin ash, resulting in hemicellulose-rich hydrolysate. determined optimal conditions were temperature 150 °C, reaction time 45 min, concentration 6% (w/v). content fractionated RH (Fr. RH) 80.1%, which significantly increased compared to raw (...

hydrolysate, soy and conventional cow milk formulas on incidence of atopic disease in high risk infants. Annals of Allergy 1989; 63: 102–6. 4 Chandra R. Five-year follow-up of high risk infants with family history of allergy who were exclusively breastfed or fed partial whey hydrolysate, soy and conventional cow’s milk formulas. Journal of Pediatriatric Gastroenterology and Nutrition 1997; 24: ...

Chickpea-chelating peptides were purified and analysed for their iron-chelating activity. These peptides were purified after affinity and gel filtration chromatography from a chickpea protein hydrolysate produced with pepsin and pancreatin. Iron-chelating activity was higher in purified peptide fractions than in the original hydrolysate. Histidine contents were positively correlated with the ir...

• A strategy of adaptive laboratory evolution in hydrolysate-based medium was developed. Evolved strains Rhodosporidium toruloides presented better tolerance to inhibitors. The strain’s ability accumulate lipids and produce carotenoids also improved. Whole genome sequencing revealed tolerance-related genes the wild-type strain. Using lignocellulosic biomass hydrolysate for production microbial ...

Prodigiosenes (prodigiosin and prodigiosin-like pigments) are known to be synthesized by only one genus of Eubacteriales and by two genera of Actinomycetales. Biosynthesis by Serratia marcescens occurs over a relatively narrow range of temperatures, although the bacteria grow over a broad range. When cultures of S. marcescens were incubated at 27 C in 1.0% casein hydrolysate, viable count and p...

1. The characteristics of absorption of individual amino acids from amino acid mixtures simulating casein and from enzymic hydrolysates of casein containing oligopeptides as well as free amino acids are known to be different. The differences, which are attributable to mucosal uptake of small peptides, involve more rapid absorption from the enzymic hydrolysates of certain amino acids which are r...

BACKGROUND During the pretreatment of biomass feedstocks and subsequent conditioning prior to saccharification, many toxic compounds are produced or introduced which inhibit microbial growth and in many cases, production of ethanol. An understanding of the toxic effects of compounds found in hydrolysate is critical to improving sugar utilization and ethanol yields in the fermentation process. I...

was first shown by Henrique and Andersen (1913). Elman and Lischer (1943) administered large amounts of amino-acids and peptides intravenously to men without any ill effects. They were able thus to maintain nitrogen equilibrium in patients who could not take food by mouth. Bassett et al. (1944) report a study of a patient with gastro-jejuno-colic fistula, who was given solutions of amino-acids ...
