A bacterial strain capable of growing on cyclohexylamine (CHAM) was isolated by using enrichment and isolation techniques. The strain isolated, strain IH-35A, was classified as a member of the genus Brevibacterium. The results of growth and enzyme studies are consistent with degradation of CHAM via cyclohexanone (CHnone), 6-hexanolactone, 6-hydroxyhexanoate, and adipate. Cell extracts obtained ...

Four rpoD hybridizing signals have been identified in the chromosome of Brevibacterium lactofermentum. Two rpoD-like genes, sigA and sigB, have been cloned and sequenced, and they encode principal sigma factors of the RNA polymerase. The deduced amino acid sequences of SigA and SigB showed very high similarities to those of Mycobacterium smegmatis MysA and MysB proteins, respectively, and also ...

In this paper Neuro-dynamic programming (NDP) is proposed as an alternative to alleviate the “curse of dimensionality” of the Dynamic programming (DP) for optimal control of a fed-batch fermentation process in the L-lysine production. The most effective and cheapest method for the Llysine biosynthesis (in biological active form) is the microbiological method via a direct fermentation. In this p...

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...

The present study aimed to isolate potential plant growth rhizobacteria (PGPR) from various crops in agricultural areas Ağrı-Turkey and their characterization. For this goal, rhizospheric soil samples of wheat, barley trefoil were collected 12 different locations Ağrı province. Bacteria isolation studies carried out with these samples. Then, determine the PGPR properties each isolate; nitrogen ...
