A Study on Nutritional Quality and Identification of Biogenic Amine Forming Bacteria in Marine Edible Species Portunus sanguinolentus and Penaeus notialis from Tuticorin, Southeast Coast of India

The aim of the study was the nutritional quality and to identify the biogenic amine forming bacteria in marine edible species Portunus sanguinolentus and Penaeus notialis from Tuticorin, Southeast coast of India. Physico chemical and biochemical analysis were carried out in both the collected samples. Results revealed that the species Portunus sanguinolentus has the high moisture and lipid and Ash value than the species Penaeus notialis. The sample of the species Penaeus notialis has the high pH, protein, and carbohydrate value is high. Biogenic amine forming bacterias isolated from the collected samples of Portunus sanguinolentus and Penaeus notialis were E.coli, Klebsiella pneumonia, Staphylococcus aureus, Proteus mirabilis, Pseudomonas aeruginosa, Salmonella species, Enterobacter aerogens and Shigella dysentria. Both the samples showed the presence of biogenic amine forming bacteria. Maximum microbial load and lowest biochemical composition were observed in samples collected from wholesale market, road side shop and street vendor. The study clearly shows that the spoilage occurs due to the duration, from the time of capturing, sometimes it takes more than two days to reach the landing centre/market from the day one of the captative process. These are the major reasons which cause the contamination in the species.
