Abstract: Plants of Withania somnifera were grown in field condition to assess the possible contribution of indigenous AM fungi to the K, Ca and Mg nutrition in presence of P fertilization. The field experiment had a split plot design with four replicates. The treatments included three levels of P fertilization (0, 75 and 150kg P2O5 per hectare) with and without fumigation. Soil fumigation with ethidium bromide was used to suppress indigenous AM fungi. Plants were sampled at 30, 60, 90 and 120 days after planting in the field. Soil fumigation decreased shoot dry weight, percent mycorrhizal infection, extra radical hyphal length and uptake of K,Ca but not Mg. P fertilization increased shoot dry weight, but decreased % mycorrhizal colonization, extra radical hyphal length at most samplilng time. The results indicate that AM fungi could increase plant biomass and K, Ca and Mg uptake at low P levels.

Abstract: Vermi wash is a liquid fertilizer collected after the passage of water through a column of earthworm culture. It is also defined as an extraction of coelomic fluid of earthworm along with its excretory products and micronutrients from soil organic molecules. Vermi wash is rich in nutrients, hormones, amino acid, vitamin and enzymes. Thus spray of vermi wash on plants helps in good growth. Along with growth promoting characteristics it is also observed that microorganism never degrade vermi wash. No bacterial and fungal growth is seen on vermi wash. It may be due to some antimicrobial activity. So, work was conducted to detect the antimicrobial activity of vermi wash.

Abstract: The application of chemical pesticides has come to be a dominant form of pest control, but the emergence of pesticide resistant strains and environmental problems have limited the use of traditional chemical strategies for disease control. In recent years there is a swing to use ecologically safe and "environment friendly" methods of protecting crops from pests and pathogens. The improvement and commercialization of biocontrol agents depends in understanding and exploiting the mechanisms involved in antagonistic interactions among bacteria, pathogens and their plant hosts. Pseudomonas chlororaphis, a soil bacterium, exhibiting versatile antifungal activity, with aggressive spermosphere and rhizosphere colonizing ability-a competitive advantage for biocontrol was isolated. In the current study, the chemotaxis and colonization ability of P.chlororaphis towards seed exudates of paddy, chilli and tomato and its colonization ability on seeds and roots was investigated. The study suggests that P.chlororaphis exhibited positive chemotaxis towards plant exudates, which contributes to their rapid colonization in the spermoshpere and rhizosphere. This ability in addition to the antagonistic potential makes the pseudomonas a potential biocontrol bacterium.

Abstract: The ray fishes viz. Dasyatis zygei and Narcine brunnae, collected from Puducherry (Pondicherry) coastal waters were screened for their antibacterial property against five common bacterial pathogens. The ether extract of both fishes showed very significant inhibitory effect against Vibrio cholerae in comparison with known antibiotic-Tetracycline. The biochemical elucidation of crude ether extracts showed the presence of salicyclic acid and sulphonic acid which are presumed to be the active substance for such antibacterial activity. The biochemical characterization of crude petroleum ether extract of Narcine brunnae showed no such bioactive substance/activity as exhibited by ether extracts of Dasyatis zygei and Narcine brunnae.

Abstract: The diagnosis fo multiple myeloma is oftern made incidentally during routine blood tests for other conditions. A diagnosis of multiple myeloma is difficult to make on the basis of any single laboratory test result. The biochemical investigation of multiple myeloma and its molecular characterization based on agarose gel electrophoresis and bone marrow aspirates were examined from human samples. Experimental samples showed increased serum calcium, total protein level and decreased serum albumin level. Bence Jones protein precipitate was present in all experimental samples and were showed the narrow and intense band of ' M ' protein on gel. When compared all experimental samples no3 could be considered a severely affected patient, due to the increased level of serum calcium, total protein and decreased level of serum albumin than other experimental cases. Bone marrow aspirate of sample no3 clearly showed the differentiation of normal plasma cells to myeloma plasma cells.The biochemical and molecular techniques used for this project has been considered as an early diagnostic tool for cancerous suspected cases. Any physician can apply this molecular characterization methodology to identify multiple myeloma condition at earlier among cancerous cases.
