Actinobacteria Study guides, Class notes & Summaries

Gram positive bacteria GRAM POSITIVE BACTERIA • Cocci:Staphylococcus, Streptococcus, Enterococcus. • Rods:Bacillus, Corynebacterium,Nocardia, Clostridium, Actinobacteria and Listeria. • In Gram-positive bacteria, the S-layer is attached to the peptidoglycan layer. • Gram +ve bacteria have teichoic acids in the cell wall. • Gram +ve: retain the crystal violet dye due to a thick layer of peptidoglycan in the cell wall that encases their cell membrane hence retains the stain. ...

Actinomycetes refer to prokaryotic organisms that are having a gram-positive cell wall. The morphology of actinomycetes is more or less similar to the fungi because they can also produce a filamentous, dense, branched and raised colony over the substrate like fungi. They are the true bacteria (not fungus) and placed in the kingdom “Bacteria” and a class “Actinobacteria”. These are ubiquitous in nature (commonly found in soil). In addition to soil, they are also very common in m...
