Štúidium rastu a produkcie biogénnych amínov niektorými mikroorganizmami za modelových podmienok

Abstract

The study was aimed at the growth of selected strains from the family Enterobacteriaceae (Escherichia coli, Enterobacter aerogenes and Klebsiella pneumoniae) in meat-peptone (MPB) broth and cabbage juice at different cultivation temperatures, and at the production of biogenic amines (cadaverine, putrescine, histamine). Bacterial growth was evaluated on the basis of specific growth rate (IJm) and lag phase (A.) calculated from growth curves. Cadaverine was produced as the first amine in MPB and cabbage juice by all studied st rains at the cultivation temperatures and at Jiving cell densities 10 6 KTJ/cm3. Putrescine was produced by E. coli only in both substrates at the cultivation temperatures. Histamine was produced by E. coli at 18 °C in cabbage juice and by Enterobacter aerogenes in both substrates at the cultivation temperatures.
