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 [...]
In this article we will discuss about the characteristics of archaeobacteria. All organisms of this group are assumed to be descendent from a common ancestor, the so called progenote and the organisms are primitive, cellular with a rudimentary not well coordinated translation apparatus. The unique feature is in the cell membrane structure. The membrane lipids are glycerol isopronyl ethers due [...]
