1 2 A Central Composite Face design was used to study growth and tyramine production 3 by two strains of lactic acid bacteria, Lactobacillus brevis CECT 4669 and Enterococcus 4 faecium BIFI-58. The effects of five physicochemical factors (incubation temperature and 5 time, environmental pH, added tyrosine concentration, and pyridoxal-5-phosphate (PLP) 6 supplementation) on cell growth and tyram...

Proline was first determined in 1901 by Fischer (2), who isolated copper Land nn-proline dihydrates from an ester fraction of an acid hydrolysate of casein. During the ensuing three decades proline was determined essentially by this procedure in the hydrolysates of more than 50 proteins by Fischer (1901-ll), Abderhalden (1902-36), Osborne (1906-ll), and other workers. That data of satisfactory ...

Lactobacillus brevis ADH (LBADH) is an alcohol dehydrogenase that is commonly employed to reduce alkyl or aryl ketones usually bearing a methyl, an ethyl or a chloromethyl as a small ketone substituent to the corresponding (R)-alcohols. Herein we have tested a series of 24 acetophenone derivatives differing in their size and electronic properties for their reduction employing LBADH. After plott...
