Abstract: Pathogenic potential of races in Sphaerotheca fuliginea on cucurbits were analysed in Eastern part of Uttar Pradesh (India). The study showed the occurrence of three races in S. fuliginea in this area. Race-3 was most wide spread and infected most of the cultivated cucurbits. Race-2 was restricted to green melon, Citrullus vulgaris var. fistulosus and Race-1 to sponge gourd, Luffa cylindrical. In addition Race-1 infected a few other cucurbits. L. cylendrica, C. vulgaris var. fistulous and C. sativus are proposed as differential hosts for identification of the three races in S. fuliginea isolates from cucurbits.

Keywords: Physicochemical, Microbiological characteristics, Dump Site, University of Port Harcourt, Niger Delta, Nigeria.
Abstract: The study was carried on the dump site at the University of Port Harcourt main gate and the characterization was done on microbial and physicochemical properties of the dump. The result of the analysis revealed that the site has pH range of 8.0 to 9.5 and a temperature range of 36 ? C to 42 ? C with a mean annual rainfall of 677.12 mm. The conductivity of the refuse samples (5.5 to 190.5 uscm1) was high due to the presence of ions. The concentration of Cadmium and Lead (1.74 to 2.91 mg/kg and 3.91 to 5.82 mg/kg respectively) were high compared to (0.36 to 0.89 mg/kg) Mercury and this may be attributed to the volatile nature of Mercury. The high values of Biochemical Oxygen Demand and Chemical Oxygen Demand is responsible for the high level of aerobic activities at the site. Further chemical analysis revealed the presence of Hydrocarbon (2.87 to 4.26 mg/kg). The total heterotrophic bacteria count ranged from 2.9 x107 to 9.2 x 107 cfu/ml and 3.0x 109 cfu/g; while total fungal count is 2.7 x 103 to 5.6 x 106 cfu/ml and 1.4 x 105 to 2.6 x 105 cfu/g. Aerobic microorganisms such as Shigella, Samonella, Pseudomonas, Bacillus, Micrococcus, Staphylococcus, Escherichia, Torulopsis, Candida, Saccharomyces, Rhizopus, Aspergillus, Fusarium and Mucor were isolated and characterized from the samples. The presence of heavy metals and pathogenic microorganisms poses danger to public health and as such, requires checks.

Abstract: Biodesulfurization is an environmentally friendly technology to reduce organic sulfur in coal by utilizing bacterial metabolism. Isolation and identification of bacteria from coal-mixed soil from South Sumatra has been conducted in order to obtain bacteria which desulfurize organic sulfur in local coal. Three viable isolates, i.e CSK2, CSK3, and CSK4, were obtained by using a mineral medium containing glucose as carbon source and dibenzothiophene as sole sulfur source. Molecular identification of 16 SrRNA gene sequences showed that the isolates had 99% similarity to genus Bacillus, which CSK2 was related to B. megaterium, while the isolates CSK3 and CSK4 were related to B. subtilis. Growth examination of the isolates within 48 hours in the dibenzothiophene in the period of incubation was 37.4, 16.7, and 25.9 percent of the initial 0.1 mM dibenzothiophene, by B. megaterium CSK2, B. subtilis CSK3, and B. subtilis CSK4 respectively. The results showed that the isolates derived from coal-mixed soil have potential to be developed in desulfurization of organic sulfur in coal.

Abstract: Our study dealt with the phenol bioremediation potential of Earthworms which were collected from a vermicomposting unit in Vellore, Tamil Nadu and maintained under proper growth conditions. Different concentrations of phenol ranging from 10 ppm to 50 ppm wee taken for the assays. All the bioremediation assays were done in the soil with phenol dispersed in water and remediation rates were observed for 24 hours, 48 hours, 72 hours, 96 hours and 120 hours. The initial concentration of phenol was increased eventually and the rate of bioremediation was estimated using 4-amino anti pyrine method. The phenol degradation activity of the gut microflora of the earthworm along with the soil microflora was also observed on a formulated media. The amount of phenol bioremediated was found higher in case of earthworm and not the microflora solely. It was found to be 30 ppm in 48 hours when the initial concentration was 50 ppm.

Abstract: Comprising over 70 % of earth ' s surface, water and its adjacent areas is undoubtedly the most precious natural resources that exist on our planet. Areas surrounded by the coast have been highly utilized since ancient times. Several National and International authorities have mandated to develop coastal structures as part of infrastructure development. The various potential problems associated with these Marine soils include land slippage, slope instability, poor foundation support and poor drainage. Problems often arise when roads or other structures are to be constructed on soft ground. In the case of Flexible Pavements, unless the subgrade is appropriately treated at the construction stage, the transportation cost will increase substantially due to deteriorated pavement performance. There are many methods of stabilization of subgrade marine clay. Treating the soil with lime, cement and lime-cement combination is a unique technique to improve the engineering properties of the marine clay. The main objective of this work is to study the effectiveness of additives at different percentages on the engineering properties of marine clay.

Abstract: Rice improvement for durable resistance to blast is difficult due to its complexity. Rice blast, caused by fungus Magnaporthegrisea, is a serious disease causing considerable economic damage worldwide. Blast is one of the destructive diseases, which causes maximum yield losses in rice. Best way to overcome the disease is to breed for disease resistant cultivars/parental lines of hybrids. The present study was conducted to analyse blast resistance in rice. Rice genotypes viz., VRPI, VRP2, B95-1 X Tetep, BPT5204 X Tetep, CO39 and CO43 were screened for blast resistance in artificial condition. The study indicated that the genes Pi9 and Pi54 recorded resistance reaction to blast pathogen occurring in Tamil Nadu. The blast resistance gene, Pi9 is present in VRP1 and VRP2 and another blast resistant gene Pi54-MAS were already identified for the genes Pi9 and Pi54 respectively. The present study indicated that the tightly linked markers showed polymorphism between resistance and susceptible rice genotypes indicating the possibility of initiating MAS for blast resistance in rice.

Abstract: The presence of iron was observed in few ground water samples analysed from the tube wells of Wayanad district. It is observed that these tubewells are more than 400 feet in depth. The presence of iron in ground water of tubewells that are 400 feet or above in depth are highly possible. The removal of iron from groundwater by a low cost natural adsorbent was investigated in the present study. The wood charcoal prepared from the hard wood of Emblica officinalis was investigated for the effective removal of iron from water samples. At first the study was conducted with synthetic solution and the efficiency of the adsorbent was confirmed and then it was directly used for the removal of iron from the ground water samples. The influence of pH, contact time, adsorbent dosage and initial concentration on adsorption efficiency was analysed. The adsorption efficiency was found to be influenced by pH, adsorbent dosage, contact time and initial concentration of the metal ion. The most favourable pH was found to be 4 and the removal of the metal gave the best result with a minimum contact time of 60 minutes. The optimum adsorbent dosage was found to be 800-900 mg. The initial concentration of the solution also was found to be influence the % removal of iron from the water samples. The equilibrium adsorption capacity of the adsorbents used for iron was measured and extrapolated using Freundich and Langmuir isotherms. The IR spectrum of the adsorbent was recorded to analysis the presence of functional groups influencing the metal ion adsorption on the plant based adsorbent.

Abstract: High quality DNA extractions are required for genetic studies. Eight commercially important fish species were chosen for molecular studies. Species and population genetic assessment requires a reliable source of biological material. Different tissues may contain varying amount of DNA (e.g scales, muscles tissues) which may not be equally dealt with by different extraction methods. A number of commercial kits for DNA extraction are available. Routine protocols have also been developed for many different tissues in different species. Yet it is often necessary to establish which is the most appropriate DNA extraction method for a certain tissue in a given research context. In the present study, DNA extracted from eight marine fish species were carried by a standard method using CTAB, a rapid phenol chloroform method, and an advanced method for fish DNA extraction. Quantity of DNA was higher in the standard methods, but adequate quantity and quality of DNA obtained when DNA was extracted by the advanced fish DNA extraction method.

Keywords: E. coli, E. coli 0157: H7, Acidic food, Hemorrhagic colitis.
Abstract: Most of the outbreaks of hemorrhagic colitis have been related with the consumption of undercooked ground beef or raw milk. Outbreaks involving acidic foods (apple cider, dry fermented sausage and mayonnaise) due to E. coli 0157:H7 have already been reported. But no attempt has been made to look for its prevalence in different Indian foods having low pH. The study was planned to ascertain the incidence of enterohemorrhagic E.coli in different foods being sold in the market. Samples of foods like mango chatni, lemonade, Imli pani, ladoo etc were taken and processed according to standard methods. Sixteen strains of E. coli were isolated and their serotype profile and ability to grow at an acidic pH was determined. The predetermined E.coli serotype was 02 (18.75 %) followed by 018,050 and 0158 (12.50 %) each. However, no enterohemorrhagic E.coli belonging to serotype 0157: H7 was isolated. Acid tolerance studies on acid adapted and non acid adapted strains of enterohemorrhagic E.coli, enteroaggregative E.coli, faecel E.coli and E.coli isolated from urinary tract was evaluated by growing them in foods like yoghurt, sweet lime juice and mango drink. The results better survival of acid adapted enterohemorrhagic E.coli as compared to other strains of E.coli.

Keywords: Breast Cancer, Diabetes, Risk factor, Insulin-like growth factor (IGF).
Abstract: There is a consensus that diabetes is associated with a spectrum of breast cancers but the underlying mechanisms are largely unknown. On the other hand, there are ongoing debates about the risk association of insulin use with cancer. We have briefly reviewed recent related research on exploration of risk factors for breast cancer and diabetes and also link between them. Epidemiological studies have shown an association between diabetes mellitus and breast cancer: there is a twofold increased risk for breast cancer in women with late onset diabetes. Hyperinsulenemia and hyperglycemia are biomarkers for insulin resistance. Both of these disorders are critical to the initial development and progression of breast cancer. The hyperinsulinaemia seen in late onset diabetes may promote breast cancer because insulin is a growth factor for human breast cancer cells. At least four mechanisms may associate diabetes mellitus and breast cancer: activation of the insulin pathway, activation of the insulin-like growth factor (IGF) pathway, altered regulation of endogenous sex hormones and altered regulation of adipocytokines.
