The results revealed that the moisture, carbohydrate, lipid, protein and crude ash content of the fish species was 75.27, 1.2, 2.42, 17.56 and 1.15 , respectively. This present study shows that the muscle of flesh of Mugil cephalus contains important w-3 and w-6 fatty acids and it is best suitable for consumption. In this present study ten essential amino acids like phenylalanine, valine, tryptophan, threonine, isoleucine, methionine, histidine, arginine, leucine and lysine were detected and all are required daily by human for healthy living. Among the eight nutrient elements investigated the most abundant was K followed by Na and Ca. The rest of the other elements Fe,Zn,Mn,Mg and Se.

The investigation suggests that aggregates of small spherical particles, with an average size of 8 nm and well defined morphology were obtained at 80 °C and the particle size appears to increase with a decrease in synthesis temperature.

Reefs are ecologically and structurally important and they are also important resources, both economically and in terms of biodiversity. Understanding of the diversity of reef ecosystem is an important basic need. Coral reefs fishes embed the concepts of beauty, diversity and complexity. In the coral reef ecosystem finfishes contribute considerably to the biomass and species diversity. Present study aims to provide basic information on reef fishes inhabiting the Cuddalore coastal waters. The present preliminary observation may stimulate better investigation in future for the reef formation and reef ichthyofauna along the Cuddalore coast.

Hence, our study focuses on production of citric acid by optimizing the conditions. Aspergillus niger was isolated from the spoiled coconut and it was studied for citric acid production. The citric acid production was optimized by screening different fermentation parameters which gives high yield. pH 3.5 gives higher production of citric acid (82.65 g l-1) and the temperature 30 °C showed maximum yield 80.68 g l-1. However, inoculum size and time course playing main role by producing maximum amount of citric acid at 5% inoculum (83.24 g l-1) and 192 hrs (85.18 g l-1) of incubation respectively. Our study reveals the optimum conditions for citric acid production are pH - 3.5, temperature 30 °C, inoculum level - 5% and the time course - 192 hrs.

In the present study cyanobacterial isolates were picked up from the contaminated water and purified, identified by morphological and cultural characteristics. Each isolate was determined by the dilution method, Ni2+, Cd2+, Fe2+, Pb2+ and Zn2+ were used in varying concentrations (10 to 1000μgL-1). Anabaena sp., Trichodesmium sp., Oscillatoria sp., Cylindrospermopsis sp. and Nostoc sp. were showed minimum inhibitory concentration (MICs) to heavy metals. From this Nostoc sp. showed high resistant so this strain use for further studies. One ml were collected each Three days interval for analyze the growth, pH and adsorbed heavy metals analyzed by ICP-OES. During this experiment 95.4% of Cd, 97.7% of Fe, 99.6% of Pb, 88.23% of Ni and 75.3% of Zn was removed by the Nostoc sp. From this experiment Nostoc sp. showed high efficiency to remove the heavy metals and this experiment may be helpful to...

Regarding enzyme status, alkaline phosphate and acid phosphatase enzyme showed very good promise in the experimental rat treated with Cyanobacteria diet. The heamatological study carried on the blood control, tobacco pasted and cyanobacteria treated rat, display no remarkable change except for slight rise in WBC, RBC, platelet, albumin, glucose, protein and haemoglobin. The present investigation confirmed that marine blue green algae can easily be digested and assimilated and therefore can serve as a source of diet for an albino rat and good remedy for affected tissues.

The present investigation aimed to study the growth regulating effect of these compounds on sweet potato (Ipomoea batatas L.). Each plant was treated with one litre of aqueous solutions containing 15mg L-1 triadimefon and 10mg L-1 hexaconazole on 40 and 70 days after planting (DAP) by soil drenching. The growth parameters of the plants were estimated on 45, 60, 75, 90 and 105 DAP. Among the triazole, hexaconazole inhibited the number of leaves, total leaf area, stem length, internodal length, leaf and stem dry weight, relative shoot growth rate significantly when compared to triadimefon. Triazole (chiefly available and plant control and yield production) treatments increase the root length, root and tuber dry weight, relative tuber growth rate, net assimilation rate root/shoot ratio, leaf dry weight per unit area, chlorophyll and carotenoid content.

The bacterial strain was isolated from municipal sewage and it was culture with different nutritional composition. The maximum lipase activity was obtained with maltose as the sole carbon source 6.5 Uml -1 , followed by lactose 4.6Uml -1 . The various salts used the best results were observed with calcium chloride 4.6 Uml -1 as and sodium chloride an inorganic source. Among the various commercial grade oil highest activity was observed with coconut oil 8.1 Uml -1 and gingili oil 6.8 Uml -1 . Amino acids are also play a significant role for the lipase production. The maximum lipase activity was observed with glycine 5.1Uml -1 followed by tryptophan 4.6Uml -1 as a supplement. The organism grows optimally in the temperature of 40 o C and pH 8. The strain isolated from the municipal sewage is industrially important from in terms of ability. These findings will be helpful in prospect for increase the production of industrial enzyme.

Production of~-and 6-hemolysins were detected in 12 out of 50 strains studied. The association between N-acetyl-~-D-glucosamini dase (NAGase) activity, plasmin activity (PL) and trypsin inhibitory capacity (TIC), known as inflammatory indicators for mastitis, and hemolytic activity were also studied. Mastitic milk decreased directly the lytic effect of both~-and 6-hemo-Iysins of S. aureus on hemolytical blood agar plates. S. aureus in healthy milk samples produced more~-hemolysin (3 times) and 6-hemolysin (2 times) when compared to S. aureus supernatants in milk from infected quarters. Furthermore,~-and 6-hemolysis correlated negatively with TIC and NAGase and PL activities. Addition of reduced glutathione (GSH) or~ mercaptoethanol into the artificial medium enhanced hemo-Iysins activity.

The most affected regions were the state of Tamil nadu and the Andaman and Nicobar archipelago. The present research analysis the impact of tsunami on finfish eggs and larvae and its distribution patterns. It deals how the tsunami impinges directly on ichthyoplankton ecology. After the tsunami effect, the eggs and larvae samples were collected and compared with previous year data of the same month (January 2004 and January 2005). We selected five stations, 0.5 1,3,5 and 10 km distance from the shoreline. During the present study a total of 1067 eggs and 285 larvae belonging to 29 families and 57 species were sorted and identified. The pre and post tsunami collection shows the significant variation on eggs and larvae distribution. During pre tsunami and zooplankton biomass was highly correlated with ichtyoplankton density with all the five station significant at 1 % level (p-value <0.01) but there is no correlation observed in the post tsunami samples.

Biosurfactant production was carried out in 3L fermentor using waste motor lubricant oil and peanut oil cake. Maximum biomass (11.6 mg/ml) and biosurfactant production (8.6 mg/ml) occurred with peanut oil cake at 120 and 132 h respectively. Characterization of the biosurfactant revealed that, it is a lipopeptide with chemical composition of protein (50.2%) and lipid (49.8%). The biosurfactant (1 mg/ml) was able to emulsify waste motor lubricant oil, crude oil, peanut oil, kerosene, diesel, xylene, naphthalene and anthracene, comparatively the emulsification activity was higher than the activity found with Triton X-100 (1 mg/ml). Results obtained in the present study showed the possibility of biosurfactant production using renewable, relatively inexpensive and easily available resources. Emulsification activity found with the biosurfactant against different hydrocarbons showed its possible application in bioremediation of environments polluted with various hydrocarbons.
