Fatty Acid Production from Amino Acids and -Keto Acids by Brevibacterium linens BL2†
Low concentrations of branched-chain fatty acids, such as isobutyric and isovaleric acids, develop during the ripening of hard cheeses and contribute to the beneficial flavor profile. Catabolism of amino acids, such as branched-chain amino acids, by bacteria via aminotransferase reactions and -keto acids is one mechanism to generate these flavorful compounds; however, metabolism of -keto acids ...
متن کاملTransport of aromatic amino acids by Brevibacterium linens.
Whole metabolizing Brevibacterium linens cells were used to study the transport of aromatic amino acids. Kinetic results followed the Michaelis-Menten equation with apparent Km values for phenylalanine, tyrosine, and tryptophan of 24, 3.5, and 1.8 microM. Transport of these amino acids was optimum at pH 7.5 and 25 degrees C for phenylalanine and pH 8.0 and 35 degrees C for tyrosine and tryptoph...
متن کاملThe utilization of amino acids and peptides by mutant strains of Escherichia coli.
In recent communications (l-3), data have been presented concerning the growth-promoting effect of peptides on artificially produced mutant strains of Escherichia coli which require certain amino acids for growth. In these studies, t,he extent of bacterial growth in a given time was plotted against the concentration, in the medium, of the appropriate amino acid or of related peptides. In this m...
متن کاملMutant strains of Escherichia coli K12 that use D-amino acids.
A series of mutations has been isolated that confer upon amino-acid auxotrophs of Escherichia coli K-12 the ability to grow when fed various D-amino acids. Several distinct systems, mediating cellular use of the D-isomers of leucine, histidine, phenylalanine, tyrosine, tryptophan, isoleucine, and valine, can be mutationally activated. Mutations leading to D-tryptophan use (dadR) all map near pu...
متن کاملAmino acids in sheep production.
Increasing production efficiency with a high standard of animal welfare and respect for the environment is a goal of sheep farming systems. Substantial gains in productivity have been achieved through improved genetics, nutrition and management changes; however the survival and growth performance of multiple-born lambs still remains a problem. This is a significant production efficiency and ani...
