Factors affecting diacetyl production by lactic acid bacteria.
Recently it has been observed that the lactic acid bacteria are primarily responsible for the production of diacetyl during concentration of orange juice. The amount of diacetyl present is used as an indicator of the degree of contamination, even though it is not a major end product of fermentation. Its presence may be detected even though little change in total acidity or pH has been noted. A ...
متن کاملExopolysaccharides Production by Lactic Acid Bacteria
Exopolysaccharides (EPSs) are high molecular weight and biodegradable polymers. They are biosynthesized by a wide range of bacteria. Lactic acid bacteria (LAB) are also able to produce EPSs. EPSs can be classified into two groups. These are homopolysaccharides and heteropolysaccharides. Homopolysaccharides are polymers which are composed of one type of monosaccharide. Heteropolysaccharides are ...
متن کاملFactors affecting conjugated linoleic acid and trans-C18:1 fatty acid production by mixed ruminal bacteria.
The objective of this study was to identify environmental factors that influence conjugated linoleic acid (CLA) and trans-C18:1 fatty acid production by mixed ruminal bacteria. Ruminal contents were collected from a 600-kg ruminally fistulated Hereford steer maintained on pasture. Mixed ruminal bacteria were obtained by differential centrifugation under anaerobic conditions and added to a basal...
متن کاملProduction of conjugated fatty acids by lactic acid bacteria.
Conjugated fatty acids have attracted much attention as a novel type of biologically beneficial functional lipid. Some isomers of conjugated linoleic acid (CLA) reduce carcinogenesis, atherosclerosis, and body fat. Considering the use of CLA for medicinal and nutraceutical purposes, a safe isomer-selective process is required. The introduction of biological reactions for CLA production could be...
متن کاملBacteriocin production by spray-dried lactic acid bacteria.
AIMS Cell survival and antagonistic activity against Listeria innocua, Listeria monocytogenes and Staphylococcus aureus were investigated after spray-drying three bacteriocin-producing strains of lactic acid bacteria: Carnobacterium divergens, Lactobacillus salivarius and Lactobacillus sakei. METHODS AND RESULTS Bacterial cell concentrates were spray-dried and stored at 4 degrees C and 18 deg...
