Abstract: A clinicomycological study of superficial mycoses and in vitro sensitivity of fluconazole, griseofulvin and clotrimazole was conducted against the clinical isolates of superficial mycosis during 4 month study period in Jabalpur central India. Direct microscopy by KOH mount and culture was undertaken to isolate the fungal pathogen in each case. Dermatophytosis was the commonest fungal infection in (70%) of positive cases followed by candidiasis (10%), P. versicolor (5%) and nondermatophyte infection (15%). The species of dermatophytes isolated were Trichophyton verrucosum, Microsporum persicolor, Microsporum audouinii Trichophyton mentagrophytes, T. terrestre, T. rubrum and Malassezia ovalis. The commonest dermatophytosis were Tinea pedis (35.7%), Tinea unguium (28.57%), Tinea corporis (14.28%), Tinea capitis (14.28%), Tinea manuum (7.1%). The commonest Nondermatophyte molds isolated were Aspergillus flavus (5%), Penicillium chrysogenum (5%) and Alternaria alternata (5%). In vitro antifungal activity of fluconazole, griesofulvin and clotrimazole were tested against the clinical isolates of superficial mycosis and all the three drugs have shown good susceptibility pattern against the genus Trichophyton and Microsporum.

Abstract: The growing need for energy independence and proposed renewable fuels has led recently to a majore expansion of fuel ethanol production especially from inedible biomass. In the process of bioethanol production pretreatment is an important process for utilization of lignocellulosic materials to obtain high degree of fermentable sugars. In this study the green coconut fiber was selected as a lignocellulosic biomass. The selected raw material was treated with alkaline sodium hydroxide (pretreatment I) and alkaline hydrogen peroxide (Pretreatment II) respectively and was subjected to microwave radiation for 10 minutes at 250 watts. Pretreated solids were enzymatically hydrolyzed and were examined in a Simultaneous Saccharification and Fermentation (SSF) process. The results showed that the raw materials subjected to pretreatment II gave a high reducing sugar yield of 35. 98 mg/g along with high ethanol yield of 1.16 g/g.

Keywords: Atrazine, biosorption, biosorbent, herbicide, fungus
Abstract: Because of due to its low vapor pressure, longer half life (180 to 360 days) and apparently low biodegradability, atrazine has contaminated the terrestrial ecosystems and has been detected in ground and surface waters inmany countries beyond permissible limits. Several fungi, bacteria and algae have been already reproted as effective biosorbents for removal of dyes, metals and even pesticides due to its low cost, non-toxic approach, regeneration capability and high efficiency for pollutant uptake. This study aims to develop a bacterial biomass which can be used as adsorbent to remove the atrazine from wastewater.

Keywords: Siaoladenectomy, submandibular gland, sublingual gland
Abstract: The mouse submandibular gland is a rich source of various biologically active polypeptides. The polypeptides are also found in sublingual gland in smaller amount (Barka, 1980 and Sporn et.al, 1982). To elucidate the functional significance of sublingual gland in absence of submandibular gland we have sialoadenectomised (removal of submandibular gland) the female mcie of 20 days old and maintained under normal conditions in the departmental animal house upto the age of three months. There after protein content, amylase activity and histological study was carried out from sublingual gland of both sialoadenectomised and normal mice. The protein content and amylase activity was increased significantly in sublingual gland of sialoadenectomised mice as compared to the sublingual gland of normal mice. While hitological study showed increase in secretory granules and length of secretory ducts in sublingual gland of sialoadenectomised mice as compared to normal mice. In sialoadenectomised mice sublingual gland shows rich glycoproteins in acini when stained with AB pH 2.5, while the acini show less reactivity with AB pH 1 as compared to normal. Therefore the present data suggest that sublingual gland tries to compensate the functions of submandibular glands related to growth factors in absence of submandibular gland.

Abstract: The present research work was carried out to study the geochemical processes controlling water composition and variations in concentration of major ions in the study area of river Damodar. The analytical findings were plotted in geochemical ternary diagrams to find out the variability in water quality over this hydro-geographic condition. The concentration of different parameters of Damodar river water range between pH (7.5-8.7), EC (160-640 ?s/cm), calcium (0.745 - 2.004 meql-1), magnesium (0.829 - 3.573 meql-1), bicarbonate (1.311 - 3.174 meql-1), ammonia (0.0-0.946 meql-1), sulphate (0.195 - 1.488 meql-1), phosphate (0.0-0.036meql-1), nitrate (0.0-0.024 meql-1), sodium (0.141-1.060 meql-1), potassium (0.059 - 0.248 meql-1), fluoride (0.019 - 0.052 meql-1). Chemical data of water samples of the study area point towards a rock-dominance zone, according to the variations in the ratios of Na+ : (Na+ + Ca2+ ) as a function of TDS in the water chemistry diagrams. Anion diagram study relating to Ca, Mg and (Na + K) reveals Ca2+ and Mg2+ are the major anion in the study area. Ternary diagram relating to HCO3, SO4 and Cl reveals HCO3- is the major anion of Damodar river water. Weathering of rock-forming minerals and anthropogenic activities and coal-based industries are the major controlling factors for water chemistry in the study area.

Abstract: The functional requirements, design, testing of food products, and finally the evaluation of products to check for overall efficiency, cost, reliability, and most importantly, safety are specified by food engineers. Food safety must be considered foremost as the overall engineering problem encountered in the food supply chain is dependent on it, and must be solved from a food safety engineering prespective. The multi-disciplinary approach will involve certain engineering components related to advanced systems for re-contamination control. This paper emphasizes the need of food safety engineering perspective in order to produce high quality food products (minimally processed) that are both safe and secure.

Abstract: Catalase is the antioxidant heme containing redox enzyme present in all mammalian cells. It catalyses the decomposition of hydrogen peroxide (H2O2) to water and oxygen. Catalase protects the cells from toxic compounds such as super oxide radical O2-. Catalase activity was studied under different days, different photoperiod within a day, under in vitro condition on Murashige and Skoog (MS) medium, under different stress conditions such as UV, water, salt and pesticide. The result suggests that stress induces the catalase activity upon to a certain limit after which it decreases. This decreased activity is due to intolerance of plant in stress condition. Peroxisomes were isolated from the plant sample and their activity was determiend. SDS-PAGE technique was used in which a single band was formed indicating that the peroxisomes might be the catalase protein.

Keywords: Reverse osmosis membranes, biofouling, water purification
Abstract: Reverse osmosis membranes appiled in produced water purification or brackish water desalination suffer from biofouling, caused by formation of a biofilm on the membrane surface. Sudden outbreaks of biofilm growht will cause a severe loss of membrane performance (decreased flux and rejection), the need for more frequent cleaning and ultimately shorter membrane lifetime. Although biological fouling has always been an issue for water quality data collection, longer deployment times are now more common due to advances in electronics and equipment design. Considering this, manufacturers are actively pursuing anti-fouling methods to reduce the impact of biofouling on the quality of collected data. Membrane fouling occurs by the irreversible deposition of retained particles, colloids, macromolecules, salts, etc, on the membrane surface and/or inside the membrane. This fouling is ubiquitous and is one of the most challenging problems to be solved before the full potential of industrial membrane filtration can be realized in a significant decline of the permeate flux.
