- ... Pisciculture by using composite effluent of Kolkata city is a common indigenous practice in East Calcutta Wetlands (ECW), a Ramsar site in India. Apprehension over the consequences of heavy metal pollution through this practice led to the present study to examine metal accumulation related histological changes in gill and liver tissues of Tilapia (Oreochromis niloticus) cultivated in the wastewate ...

- ... Bacillus anthracis makes highly stable, heat-resistant spores which remain viable for decades. Effect of various stress conditions on sporulation in B. anthracis was studied in nutrient-deprived and sporulation medium adjusted to various pH and temperatures. The results revealed that sporulation efficiency was dependent on conditions prevailing during sporulation. Sporulation occurred earlier in c ...
