MICROBIOLOGICAL APPROACH AND PHYSIOCHEMICAL ANALYSIS OF PESTICIDES POLLUTED SOIL FROM CUDDALORE DISTRICT
Journal Title: World Journal of Pharmaceutical and life sciences - Year 2017, Vol 3, Issue 1
Abstract
Microbes are an important group of organisms and they thrive in wide variety of soil habitats. In modern agricultural practices variety of synthetic chemical compounds including pesticides, e.g., zoocides, fungicides, herbicides and others are used for crop protection. Microorganisms are first to respond to those synthetic compounds let in to the environment, the natural aquifers through the runoff water. These changes will affect the process of primary production, nutrient circulation and decomposition of matter, as in which bacteria serve as an important function. The present investigation suggests that the \ influence of physiochemical analysis from ten different areas of Cuddalore district for one year of 2014-2015. The soil samples from Cuddalore distict of Thanjavur were collected one time and analyzed for parameters such as pH, electrical conductivity, organic carbon, available nitrogen, phosphorus, potassium, zinc, copper, iron, manganese, calcium, magnesium, sodium and potassium. Maximum pH was 8.26 in the Panruti village (site 7) and minimum 7.26 in T. mannalur (site 3) respectively. The higher concentration of carbon was also from Panruti village (site 7) i.e., 0.58 percentage when compared to other site areas. The bacterial count showed that Streptococcus sp. Proteus in constants (80%) had the highest count followed by Streptococcus sp, Nitrosomonas, B.subtilis (77%). Due to this organic carbon is considered as a recognizing factor for microbial population especially for bacteria including the nitrifying bacteria which were isolated and identified in each samples.
