On Amino Acids Fermentation

Fermentation of amino acids by Micrococcus aerogenes.

The anaerobic micrococci described by Foubert and Douglas (1948a) may be divided into 3 groups on the basis of ability to degrade organic compounds: (1) those capable of fermenting only glycine (Douglas, 1951), (2) those able to degrade purines (Whiteley and Douglas, 1951) and many organic acids (Foubert and Douglas, 1948b), and (3) those able to ferment purines and a limited number of amino ac...

On a hitherto unknown fermentation path of several amino acids by proteolytic clostridia.

Effects of Branched-chain Amino Acids on In vitro Ruminal Fermentation of Wheat Straw

This study investigates the effects of three branched-chain amino acids (BCAA; valine, leucine, and isoleucine) on the in vitro ruminal fermentation of wheat straw using batch cultures of mixed ruminal microorganisms. BCAA were added to the buffered ruminal fluid at a concentration of 0, 2, 4, 7, or 10 mmol/L. After 72 h of anaerobic incubation, pH, volatile fatty acids (VFA), and ammonia nitro...

Influence of vegetable amino acids and oils supplementation of on Chlorella vulgaris amino acid profile

The aim of the present research is to investigate the profile of amino acid of Chlorella vulgaris supplemented with some plant amino acid and oil extracts. The bioactive oil and amino acid from four Iranian medicinal plants, namely Oliveria decumbens, Thymus kotschyanus, Trachyspermum ammi, and Zataria multiflora were obtained. The LC-MS / MS analysis demonstrated that the major amino acids com...

Influence of peptides and amino acids on fermentation rate and de novo synthesis of amino acids by mixed micro-organisms from the sheep rumen.

The influence of different N sources on fermentation rate and de novo amino acid synthesis by rumen micro-organisms was investigated in vitro using rumen fluid taken from four sheep receiving a mixed diet comprising (g/kg DM): grass hay 500, barley 299.5, molasses 100, fish meal 91, minerals and vitamins 9.5. Pancreatic casein hydrolysate (P; comprising mainly peptides with some free amino acid...
