    ESTIMATION OF PROTEIN AND CARBOHYDRATES IN DIFFERENT PULSES
    (PSGR Krishnammal College for Women, 2016-01-05) Ashiba A; Jeeva Lavanya S; Menachi A; Shifana Asmi M; Soundarya S; Vadivukkarasi K; Sumathi R
    Pulses are essential for growth and metabolism of all living organisms. Leguminous crops are rich in protein and carbohydrates. The samples are soaked entire seed, seed coat, pulp, soaked water and also in boiled entire seed, seed coat, pulp and boiled water of black channa, white channa, fresh bean, dry bean, fresh pea and dry pea. The protein content was estimated by Bradford method and carbohydrate content was estimated by Anthrone method. The protein and carbohydrates are rich in boiled seeds than soaked seeds. The result shows the consumption of the boiled pulses is recommended and it is good for health.

    EXTRACTION OF AMPELOCISSUS LATIFOLIA AS A SOURCE OF ANTIBIOTIC
    (Muthayammal College of Arts & Science, Rasipuram, 2015-01-09) Sumathi R; Renuka Devi R
    The Antifungal activity of different solvent extract of leaf and root powder of Amplelocissus latifolia was evaluated against Aspergillus niger and Penicillium candidum. The methanol, ethanol, hexane and acetone extract showed no zone of inhibition against both the organisms. The presence of protein was identified in phosphate buffer extract using Nin hydrin test and ELISA. The leaf and root extract contains 7.6ug/ul and 7.7ug/ul of protein respectively. The phytochemical studies showed the presence of Alkaloids, glycosides, carbohydrates, tannins and phenols in the leaf extract. The root extract contains only flavonoids . The FTIR analysis of root and leaf powder of Amplelocissus latifolia showed the presence of amines, amides alcohols carboxylic acids, nitric acids and phenols

    OPTIMIZATION OF PROCESS PARAMETERS FOR LIPASE PRODUCTION BY ASPERGILLUS TERREUS USING COTTON SEED OIL AS SUBSTRATE
    (SNMV College of Arts and Science, Coimbatore, 2009-01-28) Sumathi R; Meerabai R S
    Fungi isolated from soil where screened for exogenous lipolytic activity. 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.

    BIO-DIESEL – AN ALTERNATIVE FUEL
    (PSGR Krishnammal College for Women, Coimbatore, 2005-12-07) Sumathi R; Meerabai R S
    India 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 improve
