Keywords: Water quality, culture system, bacteria, live feeds
Abstract: Water quality and bacterial flora of the live feed rotifer culture system were studied at Muttukkadu, Chennai, Tamil Nadu, during Feb 1-13, 2008. Water samples taken from the live feed rotifer was analyzed for water quality during 13 days period. The temperature, pH, nitrate and ammonia content were determined from 1st to 13th day continuously. The maximum pH (8.3) was observed on 3rd day and temperature (33.70C) was recorded on tenth day, nitrate (2.979 ppm) was recorded on nineth day and ammonia (2.931 ppm) was on seventh day. The salt tolerance test, morphological, biological, physiological and biochemical characters of the isolates were studied. The microbial studies in the rotifer culture using sea water showed the presence of Vibrio species like Vibrio parahaemolyticus, V. alginolyticus, V. anguillarum and Aeromonas sp.

Keywords: Organic manure, compost, inorganic fertilizer, greengram, yield
Abstract: Organic inputs were used to assess their influence on seed germination, growth and yield of greengram under field condition. Six treatments were used in this experiment. All the treatments showed positive influence on the parameters observed. Selected organic fertilizer application showed 8-23% plant growth, 190-230% fresh leaf weight, 33-171% plant fresh weight, 32-78% dry matter weight and 53-149% yield enhancement over control. Among the treatments NPK + organic manure gave the highest value in all the parameters observed and the poultry manure treated plants showed enhanced growth (23%) and yield (149%) which were equal to that of NPK treatment. Further, the treatment with poultry manure gave (149%) and NPK + organic manure mixture (158%) higher rate of yield increase over the control. The study strongly supports the integration of inorganic fertilizer with organic farming for a sustainable agriculture for organic diets.

Abstract: Growth inhibitory effect of methanol extract of Evolvulus nummularius was studied on antimony sensitive (AG83) and antimony resistant (K39) promastigote and amastigote forms of Leishmania donovani. The growth inhibitory studies showed that the extract was more effective on amastigotes than the promastigotes. Maximum growth inhibitory effect was observed against antimony sensitive strain, AG83 (78.9%) at 100 ?g/ml dose. Increased nitric acid oxide production in response to the extract in the activated macrophages could be the probable reason of the inhibitory effect.

Abstract: An in vitro experiment was carried out to compare the lipolytic activity of Pseudomonas sp like Pseudomonas fluorescens, P. putida and P. aeruginosa which were isolated from different enivronmental sources like air, sewage, and water. The isolated cultures were identified based on their morphological, cultural and biochemical characteristics and their lipolytic activity on different substrates were studied and compared with that of standard P. aeruginosa ATCC 19154 strain. Pseudomonas isolated from air sample was found to have higher lipolytic activity than other isolates. Highest lipase activity was observed in the fermentation media supplemented with glucose, peptone and olive oil.

Abstract: This study aims to assess the quality of drinking water in the selected colonies of Kollam, Kerala during the year 2008. Most probable number (MPN) test done to detect the coliform in the groundwater samples revealed seasonal variation in the number of coliforms which ranged from 47 to 1800 collected during the monsoon and pre-monsoon months of 2008. About eight cases of diarrhoea and 12 cases of skin ulcers were reported during the study year in the colonies which may be attributed to the use of unsafe drinking water and unhygienic conditions. It was observed that severe contamination of ground water sources is due to non-sanitary latrines, unplanned waste disposal methods, open defecation, lack of proper drainage system, scarcity of water and poor habits of water source maintenance.

Keywords: Genotoxicity, 2,4-D, alpha-tocopherol, Drosophila melanogaster
Abstract: The genotoxicity of 2,4-D, a chlorophenoxy herbicide was tested in the wing primordial cells of high bioactive strains of Drosophila melanogaster following chronic larval exposures to different sublethal concentrations ranging from 5.0 mM (LD50) up to 0.5 mM of the herbicide. The modifying effects of alpha-tocopherol (vitamin E), if any, on the genotoxic potential of 2,4-D was studied by exposing the larvae to 100 mM of the vitamin. The larvae were pre tested, concurrently treated or post-treated with the vitamin. The results clearly indicated the modifying effects of vitamin E, since there was reduction of the frequency of the wing spots, which suggests that possibly the vitamin either scavenged the free radicals generated by the herbicide or protected the genetic material of the wing primordial cells against the toxic effects of the herbicide.

Abstract: The experiments were carried out using completely randomized design (CRD) of five treatments and three replications were screened for the cultivation of the mushroom, Pleurotus eous. Sawdust, poultry droppings, topsoil, a mixture of poultry droppings and topsoil, and a mixture of sawdust and topsoil. The mixed substrates were in the ratio of 1:3. The mixture of poultry droppings and topsoil produced fruit bodies that were relatively more in number and larger in size. Sawdust (wood) which has been the traditional substrate for the growth of the mushroom produced a relatively poor yield. The ones planted on only poultry droppings did not germinate. There was significant difference in the yields from different substrates at 0.05.

Abstract: Changes in the nutrient status of polyfeed-amended soil and earthworm-inoculated soil were observed during different periods of growth of the ridge gourd, Luffa acutangula besides the vegetative growth of the plant. Levels of nutrients such as N, P, K, Ca, Mg, Mn and Cu were estimated in soils after 16, 32 and 48 days of the growth of the plant. The increased levels of essential macronutrients such as N, P and K particularly in the earthworm-inoculated soil indicate higher composting ability of the earthworms. This higher levels of N, P and K could be the possible reason for the observed incease in growth parameters of plants in earthworm-inoculated soil.
