Abstract:
Sensory, chemical, microbiological quality and bacterial flora on fresh Pseudosciaena crocea were qualitatively and quantitatively investigated. The results showed that total viable counts and total volatile basic nitrogen reached 5. 51?0. 25Log10cfu/g, 7. 84?2. 25mg/100g respectively. 279 strains of bacteria were isolated and 84.2% of them were gram negative bacteria, a small percentages of gram positive bacteria were detected (6. 1% ) . The predominant bacterial floras were composed of Enterobacteriaceae (14. 7% ), Aeromonas spp. (12. 5% ), Acinetobacter spp. (11. 5% ) and Moraxella spp. (11. 1% ) . A few percent of Pseudomonas spp. , Stenotrophomonas maltophilia and other bacteria were also found. The high number of Enterobacteriaceae showed that bacterial contamination on Pseudosciaena crocea, was mainly from cultural water field and polluted seriously by non-borne bacteria, and it should be paid attention to.
