Halophilic micro-organisms often synthesize and produce extracellular polysaccharides (EPS), whose physical, chemical properties and material properties vary greatly from each other. The extracellular polysaccharide (EPS) development of Halomonas sp. MN795630 strain type halophilic bacterium (NASH) was investigated and whether biotechnological applications were feasible. After 168 hours of incubation, 4 g/L of EPS was produced and all elements from the medium were completely used during the growth. Sucrose has been identified as the most favorable carbon source for production of EPS and maximum production (6 g/l). Beef extract level was shown to be the best for EPS production among different nitrogen sources. Optimum production of EPS (10 g/L) were achieved by supplementing the medium with 4M NaCl, pH adjusted at 9 and the medium was inoculated with 7% initial inoculum. The purified EPS were characterized chemically. Fourier transform infrared (FTIR) spectrophotometer was observed in several functional groups. EPS also demonstrated an significant inhibitor of Candida albicans ATCC 10231 and Pseudomonas aeruginosa ATCC 9027 (20.4 and 14.7 mm), respectively. EPS show satisfactory results when applied as anti-oxidant, anti-inflammatory and emulsifier.

In this study, Hydrolysate from angelwing clam (Pholas orientalis) was produced at 0, 1, 2 and 3 hrs and E/S ratio of0.5 and 3%using alcalase where the pH and temperature were kept constant at pH 8.5 and 60°C, respectively. The hydrolysates were analysed for antioxidant and functional properties such as solubility, emulsifying properties and water and oil holding capacity. Degree of hydrolysis (DH), yield, functional and antioxidant properties were influenced by the hydrolysis time and E/S ratio. Higher enzyme concentration (E/S 3%) and longer hydrolysis time increased the DH. Yield was higher at E/S 3% but reduced with hydrolysis time. Longer hydrolysis time produced more soluble hydrolysate and higher metal chelating activity but lower in emulsifying properties and DPPH activity. Higher enzyme concentration resulted in increase only in solubility and metal chelating activity. This study revealed that enzymatic hydrolysis using alcalase should be performed at shorter hydrolysis time using intermediate concentration of enzyme (E/S between 0.5 to 3%) in order to produce angelwing clam hydrolysate with collectively good functional and antioxidant properties.
