Question

Semisolid medium are used for cultivation of which bacteria

Answer 1

Liquid media are used for growth of pure batch cultures, while solidified media are used widely for the isolation of pure cultures, for estimating viable bacterial populations, and a variety of other purposes. The usual gelling agent for solid or semisolid medium is agar, a hydrocolloid derived from red algae.

Answer 2

The most common growth media for microorganisms are nutrient broths and  semi solid agar agar plates; specialized media are sometimes required for microorganism and cell culture growth.Some organisms, termed fastidious organisms, require specialized environments due to complex nutritional requirements. Viruses, for example, are obligate intracellular parasites and require a growth medium containing living cells.
