Bacteria do not show much structural detail under light microscope due to lack of contrast. So bacteria must be stained to produce color contrast.
A number of methods are available for the isolation of bacteria. The following are a few important methods:
A bacteria contains an outer cell envelope which consists of: 1. Outer cell wall 2. Inner cytoplasmic membrane Cytoplasm is present inside the cell envelope.

The structure of the Bacterial cell is very simple which can be observed under an electron microscope. The cell shows prokaryotic organization. It has following parts:
Sexual reproduction in bacteria takes place by three methods: (i) Conjugation (ii) Transformation (iii) Transduction. According to Lederberg and Tatum (1946) in two different strains of some bacterial species, recombination of genetic material takes place. They furnished a clear experimental evidence of genetic recombination mechanism.
The bacteria mostly lack chlorophyll and are unable to synthesize carbohydrates except in some forms. On the basis of the modes of nutrition the bacteria are grouped into two types:
Bacteria are unicellular and ultra-microscopic organisms, yet they play an important role in nature. They are of tremendous importance to man. They play an important role in agriculture and medicine and are the basis of many industries. Some are beneficial to man directly or indirectly, others are very harmful as they cause various plant and […]
