Ilson Whang Purified porcine gastric mucin (PGM) is an alternative biomaterial to native mucin which displays multifunctional properties for exploring a wide range of biomedical applications. The present study evaluated the in vitro (RAW 264.7 macrophage cells) and in vivo (zebrafish embryos and larvae) bioactivities of PGM. The median lethal concentration (LC50) of PGM was 197.9 µg/mL for embryos, while it was non-toxic to RAW 264.7 cells, even at 500 µg/mL. Following PGM exposure (100 µg/mL), a higher embryo hatching rate (59.9%) was observed at 48 h post fertilization, compared to the...

In this study, we evaluated the contributions of three bacteria (Pseudomonas versuta, Shewanella putrefaciens, and Aeromonas sobria) to the proteolysis, biogenic amines formation, volatile organic compounds accumulation, lipid oxidation, nucleotide catabolism, discoloration, and water migration of bream flesh during chilled storage. The results showed that P. versuta exhibited hydrolyzing activity against sarcoplasmic proteins, and all three strains could degrade myofibrillar proteins, specifically actin. The highest producer of putrescine was S. putrefaciens, which reached a maximum level 5.05 mg/kg after 14 days. Co...

Abstract Herein, the effects of grape seed extract (GSE) on the microflora and biochemical changes of container cultured snakehead (Channa argus) fillets during 11 days of chilled storage were investigated. The sensory analysis, the total number of viable colonies, the total amount of volatile basic nitrogen, and k-value analysis revealed that GSE retarded the deterioration of snakehead fillets. The degradation of inosine 5'-monophosphate and the accumulation of inosine and hypoxanthine in the GSE group were slower than these in the control group. Moreover, GSE treatment effectively decreased the accumulation of p...
