Effect of environmental parameters on lysosomal marker enzymes in the tropical blood clam Anadara granosa

  • S. Patel

The lysosomal marker enzymes, arylsulfatase and acid phosphatase, in a tropical burrowing arcid clam Anadara granosa L. have been found to exhibit seasonal variations. The activity of both enzymes decreased with increase in ambient temperature and fell with increase in salinity. Lysosomal latency for these enzymes, however, was not significantly affected by environmental parameters, including salinity, temperature, nutritional status, breeding season, etc. The physico-chemical characteristics of the habitat were found to induce reversible changes in the lysosomal latency and enzyme activity. Exposure to elevated temperature (ΔT=7° to 8°C), towards the upper limit of its physiological tolerance, was found to labilize the lysosomes. The biochemical methods optimized for the demonstration of lysosomal stability under exposure to environmental stressors could also be extended to quantify the impact of various pollutants, including heavy metals, radionuclides, etc. at the subcellular level.
