The inhibition of thermomonospora by heat sterilized lactose broth

Media for Enterobacteriaceae

“…The latter already slightly harms the original lactose containing selective media. It renders the glucose variants almost useless, because the tendency to produce inhibitory Maillard-complexes (Ingram et al, 1955;Jemmali, 1969;Einarsson et al, 1983;Vadehra and Bellamy, 1983) is very much stronger with glucose than with lactose. There is, incidentally, also no need to sterilize media for Enterobacteriaceae; the only organisms that might survive heating for about 30 rain at 80-100°C are spore-bearing bacilli and clostfidia which will be unable to develop in media containing bile salts as well as a triphenylmethane dye (Mossel et al, 1974).…”
