microbial cryptic gene activation and strain improvement: principle, application and technical aspects Kozo Ochi As bacteria and fungi have been found to contain genes encoding enzymes that synthesize a plethora of potential secondary metabolites, interest has grown in the activation of these cryptic ...
A wide variety ofculture mediaare available for the detection of hydrogen sulfide production. For tube H2S test, SIM (Sulfide Indole Motility) medium, KIA (Kligler’s Iron Agar),TSI(Triple Sugar Iron) Agar Medium, and Lead Acetate (LA) Agar are commonly used. For the petri plate method,S...
In the starch hydrolysis test, the test bacteria are grown on agar plates containing starch. If the bacteria have the ability to hydrolyze starch, it does so in the medium, particularly in the areas surrounding their growth while the rest of the area of the plate still contain non-hydrolysed...
