Keywords: PGPR traits, phosphate solubilizers, stress tolerance, agroforestry
Abstract: A study on distribution of phosphate solubilizing bacteria and fungi revealed that they are distributed more within the rhizosphere soil at the rate of 104 (PSB) and 103 (PSF) CFU g-1 soil. Phosphate solubilizing abilities were intially screened through agar plate method and later confirmed in broth medium. Efficient isolates were selected and analyzed for additional PGPR traits. Different isolates were found to be positive for indole acetic acid, gibberellic acid, siderophore, glucanase, HCN and ammonia production. Isolates with efficient ' P ' solubilization ability along with more number of PGPR traits were selected and further evaluated for their ability to sustain these characters under different carbon and nitrogen sources. Further their ability to solubilize the inorganic phosphates with increasing salt stress was evaluated. Tolerance to heavy metals and antibiotics was also studied. Two promising isolates of bacteria (PSB-8, PSB-9) and three fungal isolates (PSF-8, PSF-11, PSF-12) were selected for further studies. Bacteria were observed to be more efficient in seed germination and root colonization ability with regard to all four selected plant species. The two bacterial isolates were tentatively identified as Micrococcus luteus (PSB-8) and Pseudomonas aeruginosa (PSB-9). The two fungal isolates were identified as Aspergillus awamori and Penicillium digitatum.

Abstract: Mosquito menace in rural and urban India has reached alarming proportions. Improper urban development has compounded the problem. Extensive use of synthetic insecticides during the last few decades have resulted in environmental hazards and led to the development of physiological resistance in major vector species. Aedes aegypti is seen to transmit Dengue fever. From a selected twelve plant species of Umbelliferae family, extracts of five could induce significant mortality of A. aegypti larvae. Differential larvicidal activity was seen for various solvent extracts and both Hydrocotyle rotundifolia and Eryngium foetidum were found lethal to the larvae, the former was more effective. Synergic effect was observed when the crude extracts of H. rotundifolia and E. foetidum were used together. These two species are potential sources for larvicidal phytochemicals which may be used in mosquito control and eradication of Dengue fever. Crude extracts of three species - Ferula assa, Foetida, E. foetidum and H. rotundifolia exhibited potential larvicidal action. Development of safe biocide in future, may be done by isolation of the active principles from the crude extracts of Umbelliferae family.

Abstract: Tuberculosis, caused by Mycobacterium tuberculosis, is the commonest health problem worldwide. It is conclusively diagnosed on the basis of the presence of Mycobacterium in body fluids. Routine investigations for the detection of the disease are many times falsely negative or positive as Mycoobacterium is not easily detectable. Newer investigations have shown adenosine deaminase enzyme (ADA), a new marker for the disease. Current study was aimed to confirm the correlation between increased ADA levels in pleural fluid of patients who have been diagnosed with tuberculosis. The study was conducted at Narinder Mohan Hospital and Research Centre, Ghaziabad, India. Eighty three patients (57 males and 26 females, from age group 15-78 years) were screened for pleural effusion, out of which 67 were tuberculous and 16 non-tuberculous. The ADA levels of these samples were measured along with ELISA, culture and other routine investigations. In all 67 patients belonging to tuberculous group, the ADA levels were above 40U/L with a mean value of 115.71+35.00, whereas in non-tuberculous group only two cases were above 40 U/L with a mean value of 26.73+10.11. Reference values used for ADA levels in pleural fluid were - Normal: <40 U/L; Suspect: 40-60 U/L and Positive :>60 U/L. The test was found to be significantly specific and sensitive even at higher cut off value. Raised levels of ADA in the pleural fluid are a suggestive marker for Mycobacterium presence in pleural effusion.

Abstract: The environmental challenges posed by oil-based drilling fluids along with legislation associated with their use have necessitated the development of synthetic organic liquids that are designed to improve environmental performance. In this regard, a synthetic -based mud was formulated from palm fruit pulp ("abak" mud) and tested for its rheological properties, as well as density and pH values. The results obtained show that the derived mud ' s rheological properties compare favourably with those of bentonite mud even though its density and pH values were below the acceptable standard for any drilling operation. However, when beneficiated with soda ash (Na2CO3), local starch (cassava), barite (BaSO4) and local charcoal, the formulated mud ' s rheological parameters along with the density and pH values improved appreciably. The yield point and plastic viscosity increased by 111% and 34.62% respectively with the addition of 4.0 g soda ash (Na2CO3), 6.0 g local charcoal and 10 g local starch to the formulated drilling fluid. The pH value increased from 5.80 to 9.18 (about 58.27%) with increased soda ash (Na2CO3) content of 4g to 350mL of "abak" mud and the density increased from 994.56 kg/m3to 1150.33 kg/m3 (about 15.66%) with the addition of 15 g barite (BaSO4) content to 350mLof the formulated drilling mud. These numbers compare favourably with bentonite mud as its density and pH values were determined to be 1054.97 kg/m3 and 9.20 respectively. It can be adduced from these results that, with appropriate and adequate additives, the formulated synthetic-based drilling mud could complete favourably with bentonite as a possible drilling fluid for the oil and gas industry.

Keywords: Ewet-Offot clay, Beneficiation, bentonite, Rheological properties, Nigeria
Abstract: In a quest to provide a substitute for foreign bentonite as a drilling fluid in the oil and gas industry in Nigeria, local clay was obtained from Ewet-Offot, Akwa Ibom State, Nigeria. Water-based mud was formulated from the clays after its properties were determined and compared with those of bentonite, the clay of choice for drilling operations. The results obtained show that there was a significant difference in the formulated drilling fluid ' s rheological properties and the pH values when compared to those of bentonite. This is as a result of low concentration of sodium cations (Na++) which hinders its swelling tendency as well as clay - water attraction. When beneficiated with soda ash (Na2CO3) and sweet potato starch at a concentration of 5.0 g and 50 g respectively to 350 mL of the local mud, the mud ' s pH value increased by 70% from an initial value of 5.65 to 9.60 while the apparent viscosity, yield point and plastic viscosity increased by 229%, 200%, and 250% respectively. With the addition of barite (BaSO4) content of 10 g to 350 mL of the formulated drilling fluid, the clay density improved by 7% from an initial value of 8.60lb/gal to 9.20lb/gal. Therefore, at considerable concentration, the Ewet-Offot clay exhibits good rheological properties that would compare favourably with those of bentonite when beneficiated with soda ash (Na2CO3) and sweet potato starch. Meaning, a possible drilling fluid could be formulated from Ewet-Offot clay.

Keywords: Azadirachta indica, electrophoresis, neem, protein profiles, reproduction
Abstract: The protein profiles in neem (A. indica) were studied during the annual reproductive flush from bud formation to seed set. Four different zones of activity observed were designted as PRO-I, PRO-II, PRO-III and PRO-IV in the zymogram. It was proposed that decreased protein expression during early pre-anthesis as well as post-pollination fruit-set was due to general inhibition of quantified protein. Besides, specific banding patterns for the various growth stages also point to a definite affect in modulating active metabolism. Hence, decreased protein activity also delayed morphological expression with faint low intensity bands. High frequency bands following flowering and ovary development were point indicators for active protein metabolism and morphogenesis. This resulted in rapid growth as well as healthy fruit-set. The zymogram pattern during such periods traced high mobility, intense zones of activity. The short regeneration phase in neem leads to pharmaceutically significant product of floral inflorescence to fruit set, therefore, it is suggested that protein profiles may be the key in regulating the reproductive phase resulting in imporved morpho-physiological characteristics.

Abstract: Litterfall added by trees enriches the organic matter and nutrient content of soil under the trees. The influence of tree species was evaluated on soil organic carbon (OC), available macro (N, P and K ) and micronutrient (Zn, Fe, Mn and Cu) concentration of soil and their accumulation in the soil under 8 year old Eucalyptus tereticornis (eucalyptus), Azadirachta indica (neem), Melia azedarach (dek), Dalbergia sissoo (shisham), Albizia lebbeck (siris), Leucaena leucocephala (subabul), Acacia nilotica (kikar) and Tamarix articulata (farmah) spaced at 6 x3 m and adjoining open (control) in arid zone area of Punjab at Regional Research Station of Punjab Agricultural University (PAU) at Bathinda. Siris and eucalyptus attained more diameter at breast height and height than other tree species. The concentration and accumulation of soil OC and available nutrients were higher under trees than control. The soil OC and nutrient concentration decreased with increase in depth. Soil OC increased by 50.3% under siris followed by shisham (43.4%) and kikar (40.6%) over control (3.62 g/kg) in the surface soil layer. The OC sequestration in the 0-120 cm soil depth varied from 37.1 Mg/ha under eucalyptus to 42.2 Mg/ha under shisham. The available N concentration was higher under subabul, shisham, kikar and siris than the other tree species in the surface as well as in 0-120 cm soil depth. Available P and K were higher under kikar and subabul than other tree species. All the micronutrients were higher under the tree species as compared to control. Thus, the tree plantation can sustain the soil health by improving the different soil properties.
