A rich culture of the bacterium can easily be prepared in the laboratory. Take hay and chop it into small pieces. Put the chopped bits in water to prepare an infusion. [...]
Actinomycetes are classified into 7 families. The classification is based on hyphal and reproductive structures. Family 1: Streptomycetaceae: Hyphae non-fragmented, aerial mycelium with chains of spores with 5 to 50 or more conidia per chain e.g. Streptomyces, Microdlobaspone and Sporictilhya. Family 2: Nocardiaceae: Hyphae typically fragmented e.g. Nocardia, Pseudonocardia. Family 3: Micromononsporaceae: Hyphae non-fragmented conidia borne singly or in pairs [...]
In this article we will discuss about the features of actinomycetes with its suitable diagram. Actinomycetes are called actinobacteria or high G + C rich Gram-positive filamentous bacteria due to their mycelium like (slender and branched) structures. These filaments are long and it may fragment into much smaller units and less broad than that of the fungal mycelium usually 0.5 [...]
