Problem statement: Soil Pollution is major problem because different types of pesticides are used to control plant pest. The residual component of pesticide diffuses into the soil. It is necessary to check whether actinomycetes degrade these components and control the soil pollution. Approach: In Ayurved system of medicine the rhizome portion of Curcuma longa L. was used as an anti-inflammatory and antiseptic. Antimicrobial substances released from these plants diffuse into the surrounding soil area of the plant. Actinomycete which grow in these area were resistant to these substances. Hence considerable attention had been given in studying the effect of inhibitory substances on actinomycetes especially Microbiospora isolated from soil under cultivation of Curcuma longa L. Results: The present study deals with effect of inhibitory substances like dettol, phenol, sodium azide, lysol and crystal violet. The results were recorded on the basis of presence or absence of growth. All five isolates of Microbiospora were found sensitive against dettol. One strain of Microbiospora was found resistant to phenol. Conclusion/Recommendations: From the study performed we conclude that Microbiospora which is resistant to phenol and other inhibitory substances can be used to degrade the residual components of pesticide which are released into the soil. It may have better option to prevent soil pollution.
