Abstract

Methyl parathion, an organophosphate and cholinesterase inhibitor, is a widely used pesticide. In the present study, fresh vegetables were sampled to enumerate parathion resistant microbes. Nitrite, sulphite and hydrazine levels along with microbial load of the vegetables were determined. Bean, red spinach and coriander contained higher percentages of gram positive bacteria whereas beet ischolar_main and cabbage showed prevalence of gram negative species. Sixty bacterial strains were found to show resistance against 2000/m1 parathion and 5% of these had MIC values above 10000/m1. A gram negative bacterial strain BG023, isolated from bitter gourd surface showed maximal hydrolysis of parathion (MIC 12000/m1). In the absence of other carbon sources, the organism exhibited a faster degradation of parathion with simultaneous utilization of major detectable product p-nitrophenol during the late stationary phase of growth. The gene for parathion hydrolase was found to be plasmid borne since curing with 15 mg/ml SDS resulted in cells which failed to grow in presence of parathion but showed normal growth otherwise. The organism was also resistant to widely used antibiotics like ampicillin, vancomycin, amoxyclav, norfloxacin, bacitracin, etc. After pathogenicity testing, the organism can be used to reduce the load of organophosphate pesticides in agricultural fields.

Abstract

This paper presents the approach the design of home automation system using dual tone multiple frequency based home automation system. Today’s the demand for better home security systems has drifted over to a need for home automation. Not only does a home need to be secure but home appliances need a more refined control system. Home appliances should not be limited to only local control. There needs to be a simple and elegant way to avoid this type of situation and allow people the freedom of having complete control of their house from anywhere. Using a mobile and help of micro controller home appliances will be controlled.

Keywords
