Population selection strategies in the wedge clam, Donax incarnatus (Gmelin) from Panambur beach, Mangalore

The wedge clams, of genus Donax. form a dominant component in the infauna of sandy beaches of Indian coasts. Though not commercially very important, these clams support small fisheries along certain regions of the east and west coasts of India. Some aspects of the population biology of Donax spp have been reported by earlier werker

Seasonal variability in the condition of the Wedge clam, Donax incarnatus (Gmelin)

Variations in the condition of Donax incarnatus (Gmelin) inhabiting Panambur beach sand were followed for one year. The highest condition indices were in March (9.4) and September (8.~) and the lowest in January (3.5). Seasonal fluctuations in condition were probably related to cycles of gonadal growth and spawning. Based on the data, the best period for commercial exploitation appears to be during March and September

Allometry in the wedge clam, Donax incarnatus (Gmelin) from Panambur beach, Mangalore

In allometric relationships,only 2 parameters are compared at anyone time. Moreover, inferences about the proximate or mechanistic causes will result in differences in the intercept and slope of the allometry, hence comparisons among taxa are risky because many factors influence morphological and physiological trait

EVALUATION OF ANTICONVULSANT ACTIVITY OF MIMOSA PUDICA ROOT LINN IN SWISS ALBINO MICE

Objective: To evaluate the anticonvulsant activity of ethanolic extract of Mimosa pudica root (EMPR) in experimental mice models.Methods: Ethanolic extract of root parts of Mimosa pudica (EMPR) was prepared by a continuous method using soxhlet apparatus. EMPR in doses of 1000, 2000 mg/kg body wt along with valproate were administrated to albino mice by oral route and anti-epileptic activity was assessed by maximal electroshock (MES) and pentylenetetrazole (PTZ) induced seizure models. Abolition of tonic hind limb extension phase and an increase in seizure latency period, when compared to control group, were taken as a measure of protection in MES and PTZ induced convulsion models respectively.Results: EMPR in the dose of 1000 and 2000 mg/kg body wt of mice showed significant anti-epileptic property in both MES and PTZ induced seizure models. There was a significant abolition of tonic hind limb extension phase in MES model. There was also a significant increase in seizure latency period in PTZ induced seizure model.Conclusion: Results suggest that ethanolic extract of Mimosa pudica roots possess significant anti-epileptic activity. Further investigations are required to determine its active constituents and also its antiepileptic mechanism of action

Acid and enzyme hydrolysis to convert pretreated areca nut (areca catechu l.) husk into glucose for bioethanol production by yeasts and Zymomonas mobilis NCIM 2915

Production of renewable fuels, especially bio-ethanol from lignocellulosic biomass, holds remarkable potential to meet the current energy demand as well as to mitigate greenhouse gas emissions for a sustainable environment. Determining optimal pretreatment techniques for fermentation is essential for the success of lignocellulosic energy production process. The study involved the acid pretreatment and use of laccase enzyme to degrade the complex lignocellulosic biomass to simple sugars. Sugars so formed in turn are converted to ethanol by employing suitable yeast strains and bacterium Zymomonas mobilis. Different fermentation process like separate hydrolysis and fermentation process (SHF) and simultaneous saccharification and fermentation process (SSF) have been evaluated for the biethanol production. In separate hydrolysis and fermentation process, the higher ethanol production was in Zymomonas mobilis (44.97±3.21 g/L) and Schizosaccharomyces pombe (42.60±3.0 g/L), average ethanol production in Saccharomyces cerevisiae (33.13±1.96 g/L) and very low ethanol production in Candida shehatae (25.24±2.30 g/L). In simultaneous saccharification and fermentation process, the higher ethanol production was in Zymomonas mobilis (47.34±3.22 g/L) and Saccharomyces uvarum (44.18±2.67 g/L), average ethanol production in Pichia stipitis (34.71±1.89 g/L), and very low ethanol production in Saccharomyces cerevisiae (26.82±2.63 g/L) was monitored after the fermentation process. Structural changes of areca nut husk before and after acid pretreatment were further investigated through Scanning electron microscopy (SEM) and Fourier transformed infrared spectroscopy (FTIR). Hence, acid and enzymatic pre-treatment is more effective for ethanol production. Areca nut husk was revealed as a suitable substrate for ethanol production.Â

Role of Nanoparticles on the Alleviation of Abiotic Stress Tolerance: A Review

Nanotechnology has become a dynamically demand driven developing industry with a multiple applications in material manufacturing, computer chips, medical diagnosis, energy and health care, cancer therapy, targeted drug delivery, electronics, cosmetic industry, biosensors and crop improvement. It was estimated that by year 2014, more than 15% of all products in the global market will have some kind of nanotechnology incorporated into their manufacturing process. Nanoparticles penetrate into specific cellular locations because of their extreme small size and acquired some peculiar properties play significant role in the protection of plants against various abiotic stresses. The application of nanoparticles increased germination and seedling growth, physiological activities including photosynthesis and nitrogen metabolism, leaf activities of CAT, POX and APX, chlorophyll contents, protein, carbohydrate contents and yield, and also positive changes in gene expression indicating their potential use in crop improvement. Nanoparticles enhances the water stress tolerance via enhancing root hydraulic conductance and water uptake in plants and showing differential abundance of proteins involved in oxidation-reduction, ROS detoxification, stress signalling, and hormonal pathways. Proteomic techniques have contributed substantially in understanding the molecular mechanisms of plant responses against various stresses by providing a link between gene expression and cell metabolism. As the coding regions of genome are responsible for plant adaptation to adverse conditions, protein signatures provide insights into the nanoparticles at proteome level. The recent contributions of plant proteomic research to elaborate the complex molecular pathways and the mobility of the nanoparticles is very high, which leads to rapid transport of the nutrient to all parts of the cultivated plants with the use of nano preparations in stressful conditions

Assessment of Chemical Compounds for in vitro and in vivo Activity against Bacterial Black Spot of Mango

Bacterial black spot of mango caused by Xanthomonas campestris pv. mangiferaeindicae (Xcm) produces considerable economic losses in many parts in india. The extent to which bactericides control this disease effectively is low. In this study the bactericidal effect of different products was assessed in vitro and in vivo in mango plants under greenhouse conditions. Thirteen antibacterial substances, one commercial formulate and also combinations were tested. In vitro analysis showed that minimal inhibitory concentration (MIC) of antibacterial substances was between 2–8 µgml-1, except for copper sulphate with a MIC value of 100 µgml-1and Vancomycin, Amoxycillin which was not active at 1000 µgml-1. MIC values of commercial formulate bactrinashak  ranged between 5 and 30 µgml-1, and combinations of ciprofloxacin + copper sulphate; ciprofloxacin + bactrinashak; ciprofloxacin + copper oxychloride, ciprofloxacin + tetracycline and tetracycline + bactrinashak, showed a great effect at sub-inhibitory concentrations. Treatments including copper sulphate and copper oxychloride significantly reduced disease symptoms on plants, whereas bacitracin was less effective, where as fluconozole and penicillin does not show any inhibition. In two different field trials, the percentage of leaves symptoms was lower, after treatment with copper sulphate combinations than in inoculated controls. These combinations of different antibacterial substances results were better than copper sulphate alone. We conclude that the combination of copper sulphate with ciproflaxacin may be useful in controlling symptoms of this disease in greenhouses
