ISOLATION AND SCREENING OF PROTEOLYTIC BACTERIA FROM FRESH WATER FISH PUNTIUS TICTO

Posted on by

Abstract
Protease have a characteristic of biotechnological interest and have become industrial enzyme. The present study was undertaken to isolate and characterize the protease producing Bascillus subtilis bacteria from gut of fresh water fish Puntius ticto. Gelatin was used as the substrate in nutrient agar medium for screening and showed the maximum zone of activity (21mm) after overnight incubation and addition of the indicator in .The bacterial isolate were identified on the basis of characterized by morphological and biochemical studies. The extracellular protease production was enhanced by optimizing the culture condition. The effect of different production parameter such as temperature of 30̊ C, pH -8.0, incubation time 36 hrs, 1% starch and 1% yeast extract were optimized for maximum yield of protease enzyme.

Bioaccumulation of Heavy Metals on Fin-Fish Mugil cephalus from Nagapattinam, Karaikal and Tharangambadi Costal, East Coast of India

Posted on by

Abstract
There has been a widespread world-wide use of flathead mullet, Mugil cephalus, in fish bio monitor studies within the coastal zone. In the present study accumulation of heavy metal Zn, Cd, Hg and Pb in muscle sample of fish Mugil cephalus was estimated in southeast coastal region of Nagapattinam, Karaikal and Tharangambadi, East coast of India. The results revealed that there is elevated level in the metals in muscle of the Mullet and it was found to be Zn> Cd> Hg> Pb. Among the study areas Karaikal costal showed higher accumulation of metals then the Nagapattinam and Tharangambadi. Current investigation concluded that there is heavy metal pollution. Also Fin fish Mugil cephalus can be consider as a good indicator species.

Studies on the Role of Marine Algae Gracillaria, Sargassum and Enteromorpha on Growth Performance and Biomass Production of Penaeous Monodan (Tiger Shrimp) in the Kanyakumari Coastal of Tamil Nadu, India.

Posted on by

Abstract
The present study was carried out to evaluate the growth performance and productivity of three different seaweeds such as (Gracillaria, Sargassum, Enteromorpha) and growth and survival of Peneaus monodon. These three species of seaweeds were cultured in a tiger shrimp pond at density of 2 kg/m3. Density of tiger shrimp was 20 juvenile /m3. This experiment needs conducted in 28 days. Growth parameters were observed after 28 days of the experiments. The shrimp productivity was evaluated from the rate of shrimp survival, final individual size, growth and biomass production. Seaweeds biomass production was also observed. Collected data was analyzed using one way ANOVA, Results obtained from the present study indicates that seaweeds tend to increase shrimp productivity, it was observed by higher survival, individual size, and growth rate and shrimp biomass production. Gracillaria in increasing shrimp Gracillaria showed more productivity compared to Sargassum and Enteromorpha. It is recommended to use Gracillaria modal in integrated with tiger shrimp.

COMPARATIVE STUDY ON PERFORMANCE AND EMISSION IN FOUR STROKE DIESEL ENGINE USING DIFFERENT BLENDED FUEL

Posted on by

Abstract
In today’s relevance, the application of diesel engine holds an important role. Though the economic and environmental aspects do not support the use of diesel nowadays, it is impossible to accomplish the habitual livelihood without diesel engine. Therefore it is mandatory to devise the use of diesel in an economic and environmentally benevolent manner. In the present scenario, the combustion efficiency of compression ignition engine is very low. The improper combustion leads to poor efficiency and the emission of incomplete combustion by-products. Hence it was planned to increase the combustion efficiency and thereby to increase the performance and to reduce the exhaust emission. The combustion efficiency of diesel can be further improved by reducing the ignition delay period. The present work was aimed at to improve the performance and to reduce the emission by using different chemical compounds at a definite proportion by volume with diesel, also to compare the performance and emission of the engine while using different blended fuel. For experimentation, different blended fuels in which various chemical additives blended with diesel were used as fuel. The observations were analyzed and the results were compared with the performance and emission characteristics of the engine while using diesel without any additives as fuel. The performance characteristic curves revealed that the addition of additives enhances the combustion efficiency of diesel; the outcome of the emission test concluded that there was an appreciable reduction in emission of combustion by-products.

A survey on the traditional use of fertility inducing plants used by herbal practitioners in Tamil Nadu, India.

Posted on by

Abstract
Herbs and herbal products have been used traditionally to cure almost all ailments of human as well as animals. In the Ayurveda, Siddha, and Unani, are detail description of use of plants as medicine has been found. The South-Eastern Region of India is one of the richest biodiversity hotspots, with more than 500 species of medicinal plants used by different tribal population groups as contraceptives and treating reproductive anomalies. It has been observed that more than 70% of the people living in some tribal dominated areas of Tamil Nadu even today depend largely on traditional Medicinal system. In the present study, well-experienced traditional herbal medicine practitioners were interviewed about the uses of herbs to cure infertility and to induce fertility in three districts of Tamil Nadu, India. The preliminary survey clearly indicated that an Ethno-medicinal plants species have been still in the use for treatment of sterility or enhancing fertility or for vitality by some rural people in the Tamil Nadu.

EFFICACY OF SUGARMILL EFFLUENT ON MORPHOLIGICAL GROWTH OF BLACKGRAM [Vigna mungo(L.) Hepper]

Posted on by

Abstract
Sugar mills plays a major role in polluting the water bodies and land by discharging a large amount of wastewater as effluent. The present investigation deals with the utilization of different concentrations (control, 10, 25, 50, 75 & 100 %) of sugar mill effluent on growth and biochemical contents of black gram (Vigna mungo, var.ADT-3 ). The sugar mill effluents are having higher amount of suspend solids, dissolved solids, BOD, COD, chloride sulphate, nitrates, calcium and magnesium. It also considerable quantity of nutrients also present. The results shows that the lower concentration 10 per cent were increased the growth. The above mentioned parameters were decreased with the increase of effluent concentrations. However, the lower concentration promote the crops plants.
