Phosphorus is one of the key elements for growth and development of plants. Soils may contain a number of hundred pounds of phosphate in organic and inorganic forms per acre. Still its availability is limited to the plants due to its poor solubility and precipitation. The uses of phosphate solubilizing microbes (PSM) as fertilizer have added advantage over chemical fertilizer in terms of cost and pollutions. Therefore in present studies we are reporting isolation screening and characterization of novel PSM from its natural habitat and its concurrent effect on agricultural crop and environment. The bacteria isolated from the field of capsicum has shown highest P-solubilisation as well as P-fertilizer potential and was further characterized as Bacillus megaterium by 16s rRNA sequencing technique. © EM International Printed in India.

A novel heteronuclear bis-ligand namely 5-[4-(2-carboxyphenyl carbonyl amino)-phenyl-4-carbonyl methyl amino)-8-hydroxyquinoline was synthesized and characterized. This Bis-ligand was designated as CPHQ. Co-ordination polymers of this CPHQ bis-ligand were prepared with Cu+2, Co+2, Ni+2, Mn+2 and Zn+2 metal ions. All of these Co-ordination polymers and the CPHQ ligand were characterized by elemental analysis, IR, NMR spectral studies, thermogravimetry, electronic reflectance spectral studies and magnetic susceptibility measurement. The synthesized novel Bis-ligand and their Co-ordination polymers were screened for their antimicrobial activity. Source

The extracellular enzyme production capacity of Pleurotus ostreatus MTCC 142 was investigated for decolorization of crystal violet under solid and submerged conditions. Laccases are the major extracellular lignocellulolytic enzymes produced by fungus. Pleurotus ostreatus provided an effective decolorization of dye at 20 mg/L concentration up to 92%. Mycelial growth was observed maximum on plate for a dye concentration 20 mg/L while lowest on 200 mg/L on day 12, respectively. At all concentrations of dye studied, maximum laccase activity was observed on day 8. For 20 mg/L of dye laccase activity was 133 U/L. The decolorization was attributed to microbial action and without role of pH change; less than 0.4 pH change was observed. Manganese dependent peroxidase activity was 106 U/L, maximum on day 8 incubated with 20 mg/L dye concentration. The present study suggested that the high efficiency decolorization of crystal violet by P. ostreatus was assisted by laccase and manganese-dependent peroxidase activity and can be exploited as a promising in biological treatment of waste water containing crystal violet.
