In this article we will discuss about:- 1. Structure of a Bacterial Cell 2. Beneficial Activities of Bacteria 3. Role in Industry. 1. Structure of a Bacterial Cell: It is a prokaryotic cell in which genetic material is not organised in the form of nucleus but instead lies freely in a naked super-coiled state in the cytoplasm whence it is [...]
The following points highlight the five main types of autotrophic and heterotrophic nutrition in bacteria. The types are: 1. Photoautotrophic Bacteria 2. Chemoautotrophic Bacteria 3. Saprophytic Bacteria 4. Symbiotic Bacteria 5. Parasitic Bacteria. Type # 1. Photoautotrophic Bacteria: The bacteria possess photosynthetic pigments of two types, bacteriochlorophyll and bacteriophaeophytin (chlorobium chlorophyll). The two types of pigments respectively occur in purple [...]
In this article we will discuss about:- 1. Occurrence of Cyanobacteria 2. Morphology of Cyanobacteria 3. Cell Structure 4. Heterocyst 5. Reproduction. Occurrence of Cyanobacteria: Cyanobacteria or blue green algae are the one of most successful auÂtotrophic organisms on earth which have mastered all types of environments— fresh water, sea water, salt marshes, moist rocks, tree trunks, moist soils, hot [...]
