Keywords: Nematoctonus, CMA, PDA, pH.
Abstract: The plant parasitic nematodes infect the root tissues of the plant causing root galls that lead to reduced water and mineral uptake in the plant root system. Nematophagous fungus are used as biocontrol for the nematodes. Among those Nematoctonus are one of the species used as bioagent. Nematoctonus species produces an extensive mycelium and capture many nematodes with hour glass shaped adhesive knobs on the hyphae. Nematodes become attached to these adhesive knobs and the cuticle of nematode is penetrated by the infective hyphae. The growth and sporulation of N.robustus growing on PDA and CMA at different pH showed their ability to grow in a wide range of condition from acidic to alkaline. This can be considered as their ability for better performance in soil with wide range of soil pH.

Abstract: Plant growth promoting Rhizobacteria (PGPR) are beneficial bacteria that associate plant roots and enhance the plant growth by various mechanisms. Several bacteria thrive on abundant nutrients in the rhizosphere and some of these possess antagonistic action which safeguard the plant from pathogens and stimulate growth. In this context, it is important to investigate the natural presence of these microorganisms in the legumes viz., Groundnut and Red gram rhizosphere soils and propose a selective screening to find promising PGP strains. In this study, rhizosphere soils were obtained from different areas of Groundnut and Red gram crops in Rangareddy district. Fifteen bacteria were successfully characterized and identified as fluorescent Pseudomonas, based on their cultural, morphological and biochemical characteristics. The study was further preceded for in vitro screening of Plant growth promoting traits of the bacterial isolates viz. production of Indole Acetic acid (IAA), Ammonium, Hydrogen cyanide, Siderophores and Phosphate solubilization. All the isolates produced Ammonia and majority of the isolates showed positive results for the production of IAA, Siderophores and phosphorus solubilization. Few of the isolates displayed HCN (40%) production. The PGPR strains were also tested for in vitro antagonism against Rhizoctonia solani, Sclerotium rolfsii and Fusarium solani. Results revealed that all the Pseudomonas isolates inhibited Fusarium solani and 80 % of the isolates controlled the mycelium growth of Rhizoctonia solani and Sclerotium rolfsii.

Abstract: In the present study, the quality of drinking water in the water distribution network has been investigated at three different locations in Vellore city, India, by analyzing water samples for its various physicochemical and biological characteristics, and a survey has been conducted to relate the quality of drinking water and the health of the residents. The obtained results were compared with the permissible limits prescribed by World health organizaton (WHO) and Bureau of Indian standards (BIS). The obtained results reveal that total dissolved solids, turbidity and microbial concentrations are above the permissible limits in few cases and above the desirable limit in most cases. It was also observed that the contamination in drinking water increased along the water distribution system. Furthermore, the survey conducted among the residents in the study area indicate that at 95 % confidence level the occurrence of diarrhea, typhoid an cholera by drinking water were significant. Based on the investigation results, it is evident that the drinking water from water distribution system affects public health.

Keywords: Chervonogradska coal mine, Waste pile, Coal, Heavy metals, The Solokiya.
Abstract: Chervonogradska mine of Lviv-Volyn coal basin (Ukraine) has been producing humic coal from four beds of Namurian carbon formation since 1971. The waste pile (2.9 mln m3 of the rock) has been formed as a result of the mine activity. The authors of this article state that the waste pile rocks contain argillite (83.8 %), aleurolite (8.4 %), sandstone (4.8 %) and coal. The ash content of the rocks ranges from 47 to 98 % and on average makes up 67.9 %. The waste pile rocks have been compared with Clark in siltage (clay, argillite) enriched with Cobalt (Cc 5.4), Lead (Cc 2.1), Manganese (Cc 1.9), Yttrium (Cc 1.7), Copper (Cc 1.2), Terbium and Beryllium (Cc 1.1). The waste pile rocks have Titanium (Cc 1.0), Vanadium (Cc 0.9), Zirconium (Cc 0.8) in quantities close to Clark for sedimentary rocks. On the basis of middle, median content of chemical element, the distribution area of the chemical elements are Lead, Manganese, Cobalt and Copper. It has been substantiated that Lead, Manganese, Copper and Cobalt can get into the rocks of aeration zone adjacent to the waste pile and into the water of the Solokiya river in excessively high background quantities. To prevent possible pollution of rocks adjacent to waste pile and the water of the Solokiya, the Western Buh, and the Visla with the above mentioned chemical elements we have proposed to create geochemical artificial barriers along the perimeter of the waste pile.

Keywords: Poultry manure wastewater, Full factorial design, Biogas production.
Abstract: In this study, the best treatment condition of poultry manure wastewater (PMW) was determined for the purpose of improving biogas production by using two-level full factorial design. Five factors were chosen for factorial screening namely: agitation, reaction time, type of soil, soil to water ratio and PMW to soil water (SW) ratio. Based on main effect analysis, agitation gave highest contribution at 38.36 %. In term of interaction, agitation and reaction time gave the highest contribution at 3.33 % contribution. The best treatment condition suggested by Design Expert software was using poultry soil as source of soil at soil to water ratio 1:6, and mixed with PMW at 1:4 ratio without agitation for 5 hours reaction time. Application of this best condition showed improvement in biogas yield by 82 % where biogas yield was up to 0.0248 L/g COD by using treated PMW compared to only 0.0045 L/g COD by using untreated PMW.

Abstract: Urbanization and industrialization has brought about introduction of various pollutants that are injurious in to the atmosphere. Therefore the present study was aimed at investigating the effects of air pollution on the morphological a physiological characteristic of Manihot esculenta. Leaf samples were collected from Sites 1 and 2 located in the stone crushing and rice processing industries respectively, while the Presco Campus of Ebonyi State University was chosen as the control (Site 3). Results established a decrease in leaf length, leaf breath, leaf area and petiole length in polluted Sites 1and 2 when compared with the control. Results also showed that there were overall reduction (%) in total chlorophyll, ascorbic acid, pH and percentage increase in the relative water content. Site 1 had APTI value of 12.53, Site 2 APTI value of 13.73, while control had APTI value of 13.53. In the present study, higher APTI in the polluted sites revealed that the Manihot esculenta crop is facing stress fro pollution and as such something should be done to ameliorate the situation in order to increase food production and security as well as increase farmer ' s revenues in the area.

Keywords: Drinking water, Microbial contamination, Saudi Arabia.
Abstract: One of the major sources of drinking water in Al-Ahsa region of Saudi Arabia is the underground water, which is supplied to consumers through water vehicles. With increasing population and geographic nature of the eastern province and increasing industrialization, it is likely that underground water quality has been compromised and it may not meet the international standards set for drinking purpose. Although most coliform bacteria are harmless, the presence of any coliforms in drinking water suggests the possible presence of disease-causing bacteria, parasites, or viruses. According to US Environmental Protection Agency, the Maximum Contaminant Level Goal (MCL) for total coliforms in drinking water is zero, which means water is only considered safe for drinking when it is completely free of coliforms. We sampled 103 sources of drinking (48 samples) and tap water (55 samples) from rural (54) and urban (49) areas of Al-Ahsa region and tested for the presence of Coliforms using Blood Agar and EMB media. Out of 103 samples 59 (57%) showed growth on blood agar plates and 27 (26%) of these were positive for coliforms. Among 26 samples of drinking water samples were positive for Coliform in the urban areas. Our results show that drinking water in Al Hasa rural areas is not suitable for drinking as per standards published by US Environmental Protection Agency.

Abstract: The susceptibility of freshwater organisms to metal has been determined in a laboratory. Acute toxicity tests were performed on eight different freshwater species, namely Macrobrachium landhesteri (prawn), Poecilia reticulate and Rasbora sumatrana (fish), Melanoides tuberculata (snail), Stenocypris major (ostracod), Chironomus javanus (midge larvae), Nais elinguis (annelid) and Duttaphrynus melanostictus (tadpole).The purpose of this study was to determine the susceptibilities of species to metals based on 96-h LC50 values for Cu, Cd, Al, Mn, Fe, Pb, Ni, and Zn. In order to compare the susceptibilities of species to metals, a ' relative tolerance index ' was calculated. Based on the index, annelid N.elinguis was the most susceptible species and the snail M.tuberculata was the most resistant. Lowest 96-h LC50 values of Mn (0.36 mg/L), Fe (0.12 mg/L) and Ni (0.64 mg/L) was to N.elinguis; Cd (0.007 mg/L) to M. lanchesteri; Cu (0.006mg/L) and Zn (0.46 mg/L) to R. sumatrana; and Al(1.43 mg/L) to C.javanus. Results also indicated that among the eight organisms tested there were no extreme resistance organisms.

Roots and rhizosphere soil samples were collected in different seasons (pre-monsoon, monsoon and post monsoon). Percentage of AM colonization in root and number of spores/100gm dry soil were assessed. The result of the investigation reveals that the intensity and percentage of AM colonization varied in different forest tree species in different seasons. Maximum AM colonization and spore population were found in pre-monsoon and minimum were in monsoon season. The intensity colonization was maximum in C.tabularis (74.43 %) in pre-monsoon, A. lebbeck (69.45 %) in monsoon and S. macrophylla (67.8%) in post monsoon seasons and minimum in A. auriculiformis (53.75 %) during pre-monsoon, A.saman (24.4%) in monsoon and A.saman (19.36 %) in post monsoon seasons. The number of AM fungal spores found per 100g dry soil ranged from 164 to 376 during pre-monsoon, 27 to 310 during monsoon and 194 to 299 in post monsoon seasons. Out of six recognized genera of AM fungi, Glomus, Sclerocystis, Entrophospora, Scutellospora, Acaulospora and other unidentified spores were observed.

Abstract: A survey was conducted in the home gardens of Cherpu block in Thrissur district of Kerala state to elucidate the floristic attributes of the shrub species and to document the associated ethnobotanical information. Plant diversity analyses revealed 23 shrub species distributed in 15 families in the homegardens. These were observed to be useful in everyday life of the local inhabitants of village as medicinal, edible, ornamental, fuel wood and other uses. Most of the shrubs recorded, having more than one uses. High shrub diversity of Cherpu block may be due to less interference of monoculture crops and plantation species.

Keywords: Casuarina, Provenance, Variation, South India.
Abstract: Twenty provenances of six species of Casuarina (C. cristata, C. cunninghamiana, C.equisetifolia, C.glauca, C.unghuniana, and C. obese) were field tested for growth, stem straightness, bark, wood and fibre characters in Karunya, Tamil Nadu, India. Results obtained at 12 years age showed that C. junghuhniana was the most adaptable and fastest growing species with 54 % more volume production than the next ranking and widely cultivated species, C. equisetifolia. The SW Soe provenance of C. junghuhniana was the best provenance which recorded around 36 % more volume than the species average and the best provenance of C.equisetifolia. The stem straightness was the best in C. cunninghamiana making it suitable for pole production. Bark thickness, wood density, moisture content and fibre traits varied significantly among species and provenances providing opportunity to select for different end uses like paper and fuel wood production. Since no adverse correlation was found between growth and wood traits, selections can be made independently for different traits. Testing of more provenances of C.cunninghamiana and C.cristata from northern latitudes and hybridization between species to combine desirable traits are proposed for effective utilization o genetic resources to increase plantation productivity.
