Supply of 0.01 to 1.0 mM lead acetate to greening pea(Pisum sativum L.) leaf segments either in the absence or in the presence of inorganic nitrogen lowered total chlorophyll (Chl) content. During a time course study, there was not any appreciable effect of Pb2+ upto 4 h but thereafter Pb inhibited Chl synthesis. While supply of succinate, cysteine(More)
Nutrient regulation of alkaline phosphatase (phosphomonoesterase - PMEase) was studied in some diazotrophic cyanobacterial strains like Anabaena variabilis, Anabaena torulosa, Calothrix brevissima, Scytonema javanicum and Hapalosiphon intricatus, in response to the macronutrients (Phosphate, Calcium and Magnesium) and the micronutrients (Zinc, Copper, Iron(More)
Alkaline phosphatase (phosphomonoesterase i.e. PMEase) activity in heterocystous cyanobacteria Anabaena flos-aquae, Nostoc calcicola, Calothrix brevissima, Scytonema javanicum and Hapalosiphon intricatus is known to be temperature and pH dependent. Maximum level of enzyme activity was recorded at either 35 degrees C or 37.5 degrees C. Also, the cell bound(More)
