ABSTRACT

Biodiversity refers to the variety of life forms on earth including all living species of animals plants and microorganisms. Bacillus species has proved available model for research some species are produce copious amount of enzymes. Others can form intracellular inclusions of polyhydroxy alkanoates under certain adverse environmental conditions and few species are important pathogens. The present study was planned to isolation and identification of Bacillus species from Thanjavur district and Nagapattinam districts, Tamil Nadu India. Duration from November – February Isolation of bacterial Population in an around soil samples and physicochemical parameters of such soils were recorded such as PH, moisture, Macronutrients (Nitrogen, Phosphours, Magnesium, Calcium) and Micronutrients (Iron, Copper, Zinc, Manganese). Totally 15 different species of Bacillus from Thanjavur District and 10 species Nagapattinam taluks species of bacterial were recorded from the soil sample. Among that the identified Bacillus species are Bacillus subtilis ,B.coagulans, B.licheniformis, B.megaterium, B.mucoides, B.cereus, B.circulans, B.amyloliquefaciens, B.sphericus, B.clausii, B.odysseyi, B.halophilus, B.polymyxa, B.amylolyticus, B.thermophilus. Hence it could be concluded that included that there is no uniformity in the diversity of population during the monthly interval their distribution pattern in different geographical regions.
