| use of viscera extract from hybrid catfish (clarias macrocephalus × clarias gariepinus) for the production of protein hydrolysate from toothed ponyfish (gazza minuta) muscle. | proteolytic activity of viscera extract from hybrid catfish (clarias macrocephalus × clarias gariepinus) was studied. the optimal ph and temperature were 9.0 and 50°c, respectively, when toothed ponyfish (gazza minuta) muscle was used as a substrate. when viscera extract from hybrid catfish was used for the production of protein hydrolysate from toothed ponyfish muscle, extract concentration, reaction time, and fish muscle/buffer ratio affected the hydrolysis and nitrogen recovery (nr) (p<0.05). ... | 2013 | 23122156 |
| total and methyl mercury in the water, sediment, and fishes of vembanad, a tropical backwater system in india. | mercury contamination in the water bodies of developing countries is a serious concern due to its toxicity, persistence, and bioaccumulation. vembanad, a tropical backwater lake situated at the southwest coast of india, is the largest ramsar site in southern india. the lake supports thousands of people directly and indirectly through its resources and ecosystem services. it is highly polluted with toxic pollutants such as heavy metals, as it receives effluent discharges from kerala's major indus ... | 2017 | 28243932 |
