Thirty four arsenic resistant bacterial strains were isolated from the soil samples of Khulna Shipyard. They by growing them on nutrient broth medium containing 5 mgl-1 arsenic. From them, five finally selected, and studied their morphological, biochemical ecological characters in details. identified as Bacillus lichenifomis, polymyxa, Listeria murrayi, Moraxella urethralis Planococcus citreus....

Yolk-sac fry of Goldfish (Carassius auratus gibelio) were exposed to various concentrations of Al and pH for 3, 7 and 10 days. In this study number of dead fish, total length of larvae, yolk sac length, swimming activity, the number of gill cover movements and the number of heart beat was measured. The lowest and highest number of gill cover movements belong to the waters containing 50 mg L-1 o...

BACKGROUND Glycemic variability (GV) has recently been associated with mortality in critically ill patients. The impact of diabetes or its absence on GV as a risk factor for mortality is unknown. METHODS A total of 4084 adult intensive care unit (ICU) patients admitted between October 15, 1999, and June 30, 2009, with at least three central laboratory measurements of venous glucose samples du...

in the present study, an efficient protocol has been developed for callus induction and production of ra in callus culture of satureja khuzistanica for the first time. in vitro callus induction was achieved from young shoot tip explants cultured on ms and b5 media supplemented with different concentrations of iba (0.1, 1.0, 2.0 and 5.0 mgl-1) solely or in combination with cytokinins bap and kin...

Compost tea has a lot of potential for sustainable agriculture. The suppressive effect compost on damping-off disease in beans (Phaseolus vulgaris), caused by Rhizoctonia solani, was investigated. physicochemical properties the tested showed presence dissolved solids (7070 mgL-1), organic matter (1280 nitrate (3840 and ammonium (90.0 mgL-1). concentrations phosphorus, potassium, calcium, magnes...

Wood vinegar is a substance, derived from cooling black carbon fire, which could be used instead of chemical materials in the agriculture industry as an organic compound. In order to study the effectiveness of pine wood vinegar on physiological and photosynthesis traits of cucumber, two experiments were conducted based on a completely randomized design with six treatments including 0, 1250, 200...

l-Methionine γ-lyase (MGL), a pyridoxal 5'-phosphate-dependent enzyme, possesses anti-tumor activity. However, the low activity of MGL blocks the anti-tumor effect. This study describes an efficient production process for the recombinant MGL (rMGL) from Idiomarina constructed using the overexpression plasmid in Escherichia coli BL21 (DE3), purification, and large-scale production. The enzyme pr...
