On the Basis of Osmotic Conditions

Osmotic concentrations of substrates where upon the micro-organisms grow help classifying them as under:

(i) Osmophobic : Those micro-organisms that die of dehydration if subjected to substrates of high osmotic concentrations.

(ii) Osmophilic : Those microorganism that best grown on substrates of high osmotic concentrations.

(iii) Halophilic : Halophiles represent those microbes that preferably grow in high osmotic concentrations produced by dissolved salts.

(iv) Osmoduric : These are those microbes that grow normally on substrates of moderate osmotic concentrations but, prove to be resistant to wide osmotic changes in their substratum.

Distribution of Micro-Organisms in Nature

Various types of micro-organisms occur in the environment surrounding us. They flourish in the soil, air, water, plants animals and various food products. They micro-organisms affect our daily life considerably.
