Abstract: The present study was carried out to evaluate the effect of vesicular arbuscular mycorrhizae (VAM), phosphate solubilizing bacteria (PSB) and azotobacter (Azo) either as single or mixed inoculants on biochemical aspects of Stevia rebaudiana (Bert). The study revealed that the combined application of microbial inoculants increased the contents of total chlorophyll, reducing sugars, non-reducing sugars, shoot and root protein. The steviol glycoside which is the active principle of Stevia rebaudiana (Bert.) was found synthesized maximum in triple inoculated plants (VAM + PSB + Azo) than dual inoculated and control plants.

Abstract: Total elemental mercury (Hg) levels in the surface sediments along the Straits of Malacca were analysed by using a Hg Analyzer Model MA-1S. Based on four sampling cruises conducted between 1998-2000, the Hg levels is more than 95% of the sampling sites were lower than 100 ?g/kg dry weight while the Hg range was between 9.86-202 ?g/kg dry weight with the northern part of the Strait recorded higher concentration of Hg when compared to central and southern parts. In comparison to other regional results and established sediment quality guidelines for Hg, Hg contamination in the Straits is not serious but regular monitoring of this hazardous element is necessary.

Abstract: Different uropathogenic isolates are responsible for urinary tract infection of human being particularly in women. Gram negative bacteria Escherichia coli is most common bacteria for this infection, the rest is by Staphylococcus aureus and Klebsiella pneumoniae.The asymptomatic patients also showed bacterial infection in their urinary tract. Among different antibiotics highest sensitivity was found for Amikacin, followed by Gatifloxacin, Doxycycline and Moxifloxacin. Due to continuous change in antibiotic spectrum the updated information of antibiogram is important for proper treatment and to avoid the damage of kidney function resulting in renal failure.

Abstract: This work reports an attempt to make use of the indigenously developed high resolution IRS-IC satellite imagery to generate a database, including expertize from different organizations involved in floral, soil, microbial, hydro, socio-economic and geological fields. In the absence of large scale topographic maps, high resolution precision geocoded PAN + LISS -III imageries at 1:12,500 were used. This final database was subsequently integrated in the geographic information system environment and was used to address queries of the user organization pertaining to area statistics, location, water potential, soil suitability, agricultural suitability according the prevailing ecological conditions. etc.

Keywords: Biodiversity, Dewalgarh watershed, disturbance gradient, plant diversity
Abstract: This study deals with the plant diversity and effects of disturbance on two types of forest namely, Anogeissus latifolius mixed forest (700-1200m asl) and Quercus leucotrichophora forest (1500-2200masl) in Dewalgarh watershed in Puri District of Uttarakhand. Undisturbed, moderately disturbed and highly disturbed stands were identified and highly disturbed stands were identified within both types of forest of the watershed on the basis of canopy cover percentage, tree density ha-1and cut stumps analysis. For Q. leucotrichophora forest, the undisturbed forest stand had canopy cover>60%, cut stump index<2 and 2144 trees ha-1, whereas the highly disturbed stand had canopy cover <49%, cut stump index > 7 and 804 trees ha-1. For A. latifolius mixed forest, the undisturbed forest stand had canopy cover>45%, cut stump index <2 and 1275 trees ha-1, whereas the highly disturbed stand had canopy cover <38%, cut stump index >7 and 845 trees ha-1. The moderately disturbed stand occupied the intermediate position with respect to these parameters for both types of the forest. The study showed that the moderately disturbed stand favoured density and species richness in both the forest types. The Margalef index, Shannon diversity index and evenness index exhibited a similar trend, the highest value in moderately disturbed stand and lowest in highly disturbed stand. A sharp decline was recorded in tree density and basal area with increasing disturbance magnitude in both types of forests.

Abstract: The landslide disaster on 8 August 2009 near Kuity village in Pithoragarh district of Uttarakhand State buried two villages and took 43 lives. The landslide, triggered by cloud burst resulted in massive debris flow along a stream channel. The site is still in danger as shown by the presence of huge quantity of debris and ground cracks on the slope. Here we present inferences drawn from the field observations.

Abstract: Water is very essential component for every living organism. In the present study water quality analysis was done of Machna river passing through Betul city (M.P), India. The river Machna originates from Sasawad village near Amla Dist Betul (M.P) and joins Tawa river. The Machna river is life line for the city Betul but due to joining of domestic sewage, industrial effluents and religious activities, the water of river gets polluted. During the present study an attempt is made to assess the water quality of Machna river in Betul city and observed that due to joining of industrial effluents, water quality gets deteriorated. Presence of heavy metals at some stations indicates heavy metal toxicity in water body. Similarly higher values of BOD, COD at the sampling station joining industrial effluent indicate the pollution level.

Abstract: Contamination of the environment with toxic heavy metals is a significant problem. Conventional techniques applied to remove heavy metals from polluted water are ineffective for dilute or low concentration metal ions. For this reason, the examination of effective and innovative method becomes an important need. Biosorption process, using microbial biomass as a biosorbent has gained great attention. After a preliminary screening the most suitable bacteria for an application, which is resistant to copper, zinc and iron was isolated from the metal contaminated soil. Metal tolerance in terms of growth rate and minimum inhibitory concentration (MIC) was investigated. MIC was found to be 100?g/ml for copper, 250?g/ml for zinc and 500 ?g/ml for iron against test bacteria. The ability of bacteria for its biosorption potenial was also investigated. The adsorption isotherms obtained experimentally obeyed the Freundlich Langmuir adsorption isotherm model. Maximum adsorption levels according to the Langmuir adsorption models were 2.94 mg/gm for copper, 1.07 mg/gm for zinc and 1.34 mg/gm for iron. Biosorption was found to be higher at lower metal concentration as compared to higher concentration. The main parameters influencing biosorption namely pH and contact time had been examined. The adsorption kinetic experiments indicated that a contact period of 30 minutes was sufficient to attain equilibrium. The optimum pH for Bacillus pumilus was between pH 4 and 5 for iron, and between 5 and 7 for copper and zinc. The bacteria was able to remove 75% of copper, 76% of iron and 70% of zinc out of the solution under optimum conditions. The results suggested that Bacillus pumilus may find promising application for removal of copper, zinc and iron ions from contaminated aqueous systems.
