Distribution and Ecobiology of Antagonistic Streptomycetes from Agriculture and Coastal Soil in Tamil Nadu, India
نویسندگان
چکیده
Totally 189 Streptomyces isolates were obtained from eight different soils of Cuddalore, Tamil Nadu, India. Among them, only 78 isolates were morphologically distinct. The highest diversity in the Streptomyces populations was observed in agricultural soil with minimum occurrence of antagonistic organisms. The least number of Streptomyces strains was found in coastal soil with maximum antagonistic organisms. A connection between physicochemical properties of the soil and the Streptomyces abundance was established. There was a positive correlation between the total Streptomyces population and nitrogen, available phosphorus, ferrous and manganese, while the correlation with pH and sodium was negative. This study clearly revealed the occurrence of Streptomyces spp. and its correlation with the available nutrient in the environment.

Surface ozone (Surface O3)is a secondary pollutant and there are only limited studies on ozone in South India. Studies have revealed a strong correlation between higher ozone levels and warmer days. Surface O3 along with its precursors like NO2, CO and CH4 are being measured at Kanyakumari (8.0780° N, 77.5410° E), TamilNadu, India and in this paper we present the summer time variation of ozone ...
