Isolation, characterization and evaluation of hydrocarbon degrading bacteria from contaminated soils in Kerala
Petroleum refineries around the world have generated solid wastes during refining process and stocking of crude oil. This leads to critical effects in the environment. Thus remediation of these hydrocarbons by natural decontamination is of at most importance. Bioremediation is a non-invasive and cost effective technique for the clean-up of these petroleum hydrocarbons. In this study I have investigated the ability of microorganism present in the soil sample collected from petroleum contaminated area of Kalady, Kerala, to degrade the hydrocarbons. The soil samples collected were initially screened for diesel degraders by culturing isolates in BH media with diesel as carbon and energy source . The diesel oil degraders were identified as bacillus and pseudomonas based on the morphological and biochemical studies The ability of these microorganisms to grow by using diesel as carbon source were analysed by culturing them in BHMS broth and evaluating their growth colourimetrically
Screening of exogenous IAA producing plant growth promoting Rhizobacteria from agriculture soil
Phytohormones (plant hormones) are chemical messengers that affect a plant’s ability to respond to its environment. There are five major classes of plant hormones: auxin, gibberellin, cytokinin, ethylene and abscisic acid. These hormones can work together or independently to influence plant growth. Of these five hormones, auxin is the most important one. The most important member of auxin family is indole-3-acetic acid (IAA), which generates the majority of auxin effects in intact plants, and is the most potent native auxin. The indole acetic acid (IAA) production is a major property of rhizosphere bacteria that stimulate and facilitate plant growth. Plant growth promoting rhizobacteria (P...
A study on the role of micro finance institutions in economic empowerment with special reference to Changanacherry Taluk, Kerala
India is a home to the largest population of poor in the world and out of its total population there are nearly 75 million poor house-holds in India, thus it has become the prime obligation of the regulators to provide some definite solution for poverty alleviation. Microfinance has several other developmental objectives like mobilization of savings. It has also been used as inducers in different community development activities as an entry point in the community organizing program and as an ingredient in a larger education or training exercise. For this study, population consist of clients of micro financing institutions in Changanacherry Taluk. In this study for the purpose of primary data...
A study on the importance of micro finance on Kudumbasree members with special reference to Purapuzha Panchayath, Kerala
The most widely published feature of Kudumbasree is the setting up of micro enterprises using local resources as well as skills. Micro enterprise development is viewed as an opportunity for providing gainful employment to the people below poverty line and thereby improving their income and living standards. Micro finance in India started in the early 1980s with small efforts or forming informal SHG to provide access to much needed saving and credit services to the marginal population more importantly in rural areas. National bodies like the Small Industrial development Bank of India (SIBI) and NABARD are devoting significant time and financial resource to micro finance sector. The main objec...
RAPD, Antimicrobial and Anticancer Activity of Musa Varieties in Kerala
Banana is one of the most important food crops all over the world. There are around 365 varieties of bananas available throughout the world. Banana is a traditional medicine for diabetes, cancer, diarrhoea and also highly nutritional food crop. In this study, commonly used varieties of banana are taken for characterization by morphology and genotype which is based on International Plant Genetic Resources Institute and RAPD analysis. Five varieties were morphologically similar in parameters such as leaf habit, pseudo stem appearance and peel color. RAPD analysis proved that these varieties of banana are closely related which coincides with the morphological characterization. Also, this study ...
Service Quality and Customer Satisfaction in Private and Public Sector Banks in Kerala: A Comparative Study
Quality and satisfaction are the key indicators of corporate competitiveness. Measurement of customer satisfaction based on the service quality is to be done independently and objectively to establish baseline for improvements in service delivery. Assessing customer satisfaction periodically allows bank management and policy makers to identify customers’ needs, expectations, perception and the perception- expectation gaps. The current study covers a comparative analysis of service quality and customer satisfaction among the customers of public and private sector commercial banks in Kerala. The research questions that are addressed in this study are on expectations and perceptions of retail...
Green synthesis of copper and zinc nanoparticles from plant extracts and evaluation of their antifungal activity against Fusarium oxysporum cubense: an overview
Soil borne diseases which are caused to various plants include a wide variety of soil microbes like fungi and bacteria, among which Fusarium wilt is one such disease caused by Fusarium oxysporum cubense in banana plants. Wilt disease or the panama disease of plant is among the most destructive disease of banana in the tropics and even the control methods like field sanitation, soil treatments and crop rotations have not been a long term control for this disease. An alternative method of treating Fusarium oxysporum was adopted by using various natural plant leaves of Chromolaena odorata, Justicia adhatoda, Glycosmis pentaphylla, Azadirachta indica, Gliricidia sepium, Piper nigrum, Ocimum tenu...
Morphological characterization and nutritional analysis (leaf and pseudostem) of selected banana varieties in Kerala: an overview
Banana is an important fruit grown and consumed in tropics and sub tropic regions. It is the edible fruit usually seedless which can be grown in any climatic condition. It is rich in carbohydrates, fat, proteins, vitamins, minerals and water. A comparative study between 10 different Musa sp. in Kerala was conducted to study the various morphological characteristics. Each of the banana plant differ from each other on the basics of its height, length, colour, pseudostem, leaf, flower bud and fruit. The nutritional components such as moisture, crude protein, crude fibre, ether extract and total ash of pseudostem and leaf of selected varieties of Musa were analysed. For this pseudostem and leaf of 4 different varieties were selected and tested. The test was based on the AOAC method. The result shows that the crude fibre content of pseudostem and leaf is high with certain nutritive value.
Evaluation of anti-microbial and anti-oxidant and phytochemical activity of Eupatorium triplinerve Vahl against wound infections
Medicinal plants have bioactive compounds which are used for various human disease and also an important role in wound healing. The present study is to investigate about the Antimicrobial, phytochemical and antioxidant activity of Eupatorium triplinerve Vahl. The extracts are studied against human wound and burn pathogenic bacterial stains. E. coli, Klebsiella species, Pseudomonas species, Staphylococcus aureus, Enterobacter species. From the phytochemical study is shows the presence of steroids, glycosides, tannins, phenols, saponins and flavonoids. Plant extracts compounds were separated by thin layer chromatography and identification based on Rf values. The presence of vitamin C play and important role of antioxidants.
Green synthesis of copper and zinc nanoparticles using different varieties of banana starch, latex and sap and evaluation of their antifungal activity against Fusarium oxysporum cubense
Soil borne diseases which are caused to various plants include a wide variety of soil microbes like fungi and bacteria, among which Fusarium wilt is one such disease caused by Fusarium oxysporum cubense in banana plants. Wilt disease or the panama disease of plant is among the most destructive disease of banana in the tropics and even the control methods like field sanitation, soil treatments and crop rotations have not been a long term control for this disease. An alternative method of treating Fusarium oxysporum was adopted by using various banana parts mainly its peel, pulp sap and its latex of varieties such as Robusta (B1) Musa acuminate Colla (AAA), Etha (B2) Musa x paradisiaca (AAB), ...
