Abstract Lactococcus lactis subsp . cremoris is a lactic acid bacterium commonly used in the cheese manufacturing industry. It known to produce antibacterial peptides and has recently received attention for its role as probiotic strain. Here, we report isolation of new strain, RPG-HL-0136 (RPG0136) from dried compost, which exhibits strong activity. When RPG0136 was fed mice, it increased intes...
Propionic acid production from glycerol was studied using Propionibacterium acidipropionici DSM 4900 cells immobilized on polyethylenimine-treated Poraver (PEI-Poraver) and Luffa (PEI-Luffa), respectively. Using PEI-Luffa, the average productivity, yield and concentration of propionic acid from 40 g L(-1) glycerol were 0.29 g L(-1) h(-1), 0.74 mol(PA) mol(Gly)(-1) and 20 g L(-1), respectively, ...
The effect of monensin (0 or 33 mug/g of diet) upon rumen fermentation in the presence and absence of methanogenesis was determined in vitro by using mixed rumen organisms continuously cultured for 17 days. Methane was inhibited by dichloroacetamide (DCA; 32 mg/day) or by a pH of 5.1. Monensin effected a significant decrease in the ratio of acetic to propionic acid in the presence or absence of...
PurposeThermodynamically, lactic acid and ethanol allow the best energy recovery among all common metabolites for methane production. The main objective of this work was to favor fermentation OFMSW better production.MethodsAs a first step, fermented using two different inocula: Yeast (Saccharomyces cerevisiae) anaerobic granular sludge from UASB wastewater treatment plant. naturally occurring m...
Soybean meal (SBM) was treated with acid or alkali to determine effects on N solubility, in vitro NH3-N accumulation, in situ N degradability, and N digestion and retention in growing lambs. The following SBM treatments resulted in decreased (P less than .05) N solubility and in vitro NH3-N accumulation compared with control SBM: spraying with 2.5 or 5% acetic or propionic acid, soaking in .5 N...
Hay producers working in humid environments are wellacquainted with the consequences of baling moist hays, which include heating, molding, losses of dry matter (DM) and nutritive value, and the possibility of spontaneous combustion. These problems are initiated through respiration by active plant cells and/or microorganisms associated with the hay that consume plant sugars in the presence of ox...
For treatment of saline wastewater, the feasible approach to mitigate salt inhibition is using acclimated salt-tolerant sludge. The aim this work was verify if use sludge (AS) also could alleviate salinity stress on acidogenic fermentation food waste (FW) under environment. responses volatile fatty acid (VFA) production and microbial community were investigated. Results showed that VFA reduced ...
