Porteresia coarctata (= Oryza coarctata) is a perennial halophytic wild grass, relative of rice and member of the family Poaceae. It acts as a pioneer species in the succession process of mangrove formation along the estuaries of India. The sequestering carbon, fertilizer in aquaculture and salt tolerant property of this mangrove associate has been dealt with by a number of workers earlier. But, the present study was conducted to evaluate the antibacterial property of aqueous, acetone, ethanol and methanol extracts of Porteresia coarctata collected from the Matla river of Indian Sunderban delta. Collected sea weeds were screened for their antibacterial studies against gram positive bacteria including Staphylococcus aureus, Streptococcus fecalis and Bacillus subtilis and gram-negative bacteria including Escherichia coli, Pseudomonas aeruginosa, Salmonella typhi, Klebsiella pneumonia and Proteus vulgaris using disc diffusion method. Present study shows that ethanol extracts of Porteresia coarctata has maximum antibacterial activity against E.coli (1.2±0.01 mm) and Streptococcus fecalis (1.4±0.01 mm) at an MIC of 700 μg/mL and 500 μg/mL, respectively. Along with the antimicrobial activities, seaweeds also showed anti-diabetic activity and but have no anti-inflammatory activity. Therefore, the results suggested that these sea weeds could be exploited in the management of various infectious diseases and can be used as for pharmaceutical purpose.

Total bacterial count (TBC), total coliform (TC), total faecal coliform (TFC), E. coli and Bifidobacterium sp. in the flesh of edible oyster (Saccostrea cucullata), in three collecting stations of Sundarban, varied during different seasons of a year. The bacterial load was maximum in monsoon and minimum in pre monsoon. Heavy metal content in the flesh showed following sequence: Zn>Cu>Pb, with maximum values during monsoon and minimum values during pre-monsoon. Further, maximum antioxidant enzyme (Catalase and Superoxide dismutase) activities in the oyster were recorded during pre-monsoon which decreased in monsoon, while the level of lipid peroxidation (free radical) was minimum in pre-monsoon. It appears, therefore, that the antioxidant activity in oyster was inversely proportional to the heavy metal concentration in the flesh. Hence, monitoring of heavy metal content in the water of Sundarban estuary is considered vital towards the survivability of the oysters.Keywords
