The highest lipase activity was found in an isolate of Aspergillus terreus. Optimal cultural conditions influencing the growth and production of extra cellular lipase from this fungus was investigated. The lipase yield was maximum on day 5 of incubation, when the medium was supplemented with maltose and cotton seed oil as carbon source and potassium nitrate as nitrogen source, at pH 4 and at a temperature of 400 C. The possibility of using the lipase thus produced for transesterification of cotton seed oil to biodiesel was investigated.Item BIO-DIESEL – AN ALTERNATIVE FUEL(PSGR Krishnammal College for Women, Coimbatore, 2005-12-07) Sumathi R; Meerabai R SIndia is one of the countries in the world with billions of population and faces problems in this regard to the fuel requirement for increased transportation demand and now imports about 70% of its petroleum requirement. The current year consumption of diesel in India is approximately 40 million tons forming 40% of the total petroleum products consumption. The potential demand for biodiesel at 20% blend is estimated at 13.38 million tons by 2012. Indian oil corporation and Indian railways intend to use biodiesel in large quantities. The government is encouraging corporate and entrepreneurs to set-up biodiesel plants. Formers can develop and utilize waste lands and improve incomes, rural women labour will have more employment opportunities and soil fertility and the conditions will improveItem BIOPLASTICS– UTILISATION OF VEGETABLE AND FRUIT WASTE FOR THE USE OF GREEN APPLICATIONS(Gujarat Institute of Desert Ecology, Bhuj, 2020-03-07) Rubalakshmi S; Uma EThe major sources of land pollution include plastics, metal and glass containers, food wrapping, worn-out machinery, old furniture, garbage, etc. Plastics have become a large environmental problem. However, it is slow to degrade. The plastics in excess produced will be deposited as landfill and are degraded very slowly, which can cause the original products to remain in the landfills for hundreds or even thousands of year. The prominence of plastic pollution is correlated with plastics being economical and durable, which lends to high levels of plastics used by humans and plastic pollution, can unfavorably affect lands, waterways and oceans. In order to reduce the usage of Plastics, currently Bioplastics are produced from the agricultural and vegetable wastes. Bioplastics are plastic materials produced from renewable biomass sources, such as vegetable fats and oils, corn starch, straw, woodchips, sawdust, recycled food waste, etc. Bioplastic can be made from agricultural by-products and other containers using microorganisms. At present we could see the use of conventional plastic in every corner of the world, but their use raises serious environmental issues and public irritation because of their non-degradable nature. Hence, nowadays it is indispensable to have a potential bioplastic material in alternate over the conventional plastics. The bioplastic obtained will be environmentally friendly, trendy, user friendly and degradation tractable properties. There were plenty of reports on bioplastic synthesis using vegetable and fruit waste, however, there are less reports on tractability biodegradation, thus produced biodegradation tractable plastic could play vital role in the market for the sustainable use and commercial value added product development. The bioplastic produced through this method could be substantial and the biodegradable tractability is one of the main challenges in developing bio plastic material. The current report has made an effort towards the synthesis and characterization these types of natural polymeric material. Certainly, the research is a long way to go for both economic and environmental friendly products using bioplastic materials or bio polymer.Item PHYSICO - CHEMICAL PARAMETERS OF TEXTILE DYE EFFLUENTS AND SOILS COLLECTED FROM TIRUPUR DISTRICT, TAMIL NADU(Department of Bioscience, Sri Krishna Arts and Science College Coimbatore, 2017-02-10) A, Jeevitha; S, Mohanapriya; L, Pavithra; V, Deepthi; M S, Sri Saranya; S, Srimathi; E, UmaTextile industries are large industrial consumers of water as well as producers of wastewater effluents. The continuous application of effluent on soil and water may change its quality as well as its fertility. In this study the physico chemical parameters such as colour, pH, Electrical conductivity (EC), Total solids, Total suspended solids (TSS), Total dissolved solids (TDS), Total organic carbon (OC), Biological oxygen demand (BOD), Chemical oxygen demand (COD), Total nitrogen, Phosphate, Exchangeable Potassium, Exchangeable Sodium of the untreated textile effluents were analyzed. In this regard, the result indicates that the physico-chemical properties of industrial effluent are higher than the permissible limits therefore it affects the nature of soil and water. Hence there is a need of advanced methods of treatment of effluent water so that the waste water generated as the product of treatment can be reused for various biological meansItem THE MYCORRHIZAL STATUS OF SOUTH INDIAN EPIPHYTIC ORCHIDS(The Postgraduate & Research Department of Botany, St. Thomas College, Kozhencherry, Kerala, India, 2009-10-28) Sathiyadash K; Uma E; Muniappan V; Sarah jaison; Muthukumar TThe study is to screen certain orchid species growing naturally in southern India for their mycorrhizal status and to assess the role of root morphology in determining the mycorrhizal status of orchidsItem ARBUSCULAR MYCORRHIZAL FUNGAL ASSOCIATIONS IN ZINGIBERACEAE AND COSTACEAE(The Postgraduate & Research Department of Botany, St. Thomas College, Kozhencherry, Kerala, India, 2009-10-28) Uma E; Sathiyadash K; Muniappan V; Sarah jaison; Muthukumar TWe provide information on the AM fungi incidence exclusively in Zingiberaceae and Costaceae, which will provide an opportunity to extend our knowledge on the AM association in these plant familiesItem MICROBIAL DEGRADATION OF LOW-DENSITY POLYETHYLENE (LDPE) BY FUNGUS ISOLATED FROM LANDFILL SOIL(Avinashilingam institute for home science and higher education, Coimbatore, 2019-12-18) Jeeva Dharshni S; Kanchana MPlastics are natural or synthetic represent the class of polymeric substances. A stable increase in the use of plastic products has accelerated the pollution. Several attempts have been made to control the problem at large by resorting to both chemical and biological methods. Eradication of pollution by chemical methods leads to many side effects such as, release of toxic chemicals and gases into the atmosphere. Therefore an alternative method must be identified and it should be eco-friendly manner. Hence a current study is focused on identify the biological method for the degradation of plastics without any side effects. Low density polyethylene polymer can be degraded by microorganisms or enzymes by means of cutting down the molecular chains. A low density polyethylene (LDPE) is one of the hazardous polymers used for the present study and makes it degrade fully in a rapid manner. There are two fungal strains Aspergillus sp. and Xylaria sp. were identified for their high degradable activity. After 30 days of incubation the efficacy of fungal isolates for their polymer degradation was determined through various parameters such as pH variation, Optical Density of the culture and estimation of CO2 during degradation process.Item FLORISTIC DIVERSITY AND ETHNOMEDICINAL ANALYSIS OF ANGIOSPERMIC PLANTS IN KUMARANKUNDRU HILL, ANNUR, COIMBATORE(St.Xavier’s College, 2019-11-28) Preethi Jenifer S; Lekha K; Kanchana MTaxonomy is the study to gather acquaintance of various kinds of plants in earth and its systematic grouping, the main aim of taxonomist to deal with the identification, nomenclature and classification of plants in scientific manner.
