Previous studies indicate that the cartilage contains bioactive compounds, glucosamine, and chondroitin, but the extracted product is unstable (easily melted during storage) and smelly ammonia. This study aims to obtain a stable extract product without the smell of ammonia by adding different absorbers. The experiment used a Complete Randomized Design on applying absorbers, HPMC, Cab-Osil, and Avicel PH 101. The parameters measured were the yield and the organoleptic of the shark’s extract product. The microstructural observations used a Scanning Electron Microscope (SEM), while the chondroitin sulfate content analyses used high-performance liquid chromatography(HPLC). Results showed that adding different absorbers significantly influenced the yield and organoleptic of the shark’s cartilage extract. The use of Avicel PH 101 (90%), Cab-Osil (9%), and Hydroxy Propyl Methyl Cellulose (HPMC) (1%) gave the highest amount of extract, as much as 5.02 g (16.73%). The organoleptic was without smelling salts, whitish beige color, and dry structure (stable). The microstructure of the shark’s cartilage extract product at this treatment had a dense structure with a soft surface. In contrast, the extract without an absorber addition had a sharp, needle-like microstructure. The chondroitin sulfate content of the shark’s cartilage extract product was the highest at this treatment.","PeriodicalId":21935,"journal":{"name":"Squalen Bulletin of Marine and Fisheries Postharvest and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136036180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Disease outbreaks could occur in catfish farming activities caused by pathogenic bacteria. Several species of pathogenic bacteria can cause disease in catfish, resulting in mass death. This can lead to decrease in the food quality of freshwater fishery products, especially catfish. In cultured system, aquaculture occurrence of diseases can cause severe financial losses. Catfish samples were obtained from catfish farming with clinical symptoms of reddish spots on the outside of the body. Bacteria were isolated from the kidney and liver under aseptic conditions. These bacteria isolates were identified through their colony morphology, Gram staining, biochemical tests, molecular test, and antibacterial test of Bacillus spp. using spot and disc diffusion test.

The antibacterial test results of APD10 isolates of Bacillus velenzensis species inhibited GL2 pathogenic bacteria with an inhibition zone of 22.15 mm in the very strong inhibition zone and HL2 pathogenic bacteria with an inhibition zone of 8.5 mm in the moderate inhibition zone.

Our study aimed to evaluate the potential of marine yeast Aureobasidium melanogenum MTGK.31 as a fermenting agent for G. verrucosa and characterize the seaweed metabolite profile and antioxidant activity after fermentation. The seaweed was fermented using A. melanogenum MTGK.31 in a medium consisting of yeast extract, peptone, and glucose. The fermentation was done for 24, 48, and 72 hours. Total plate count and pH were measured after each fermentation period. The primary and secondary metabolites of G. verrucosa in each fermentation were observed. Antioxidant assay using the 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) method was conducted, followed by total phenolic content using the Folin-Ciocalteu method. It was highlighted that yeast colony increased during the fermentation, while the pH level was decreasing. We found that the fermentation not only boosted some elements in primary metabolites, but also increased G. verrucosa bioactive groups. After 72 hours of fermentation, the G. verrucosa percent radical scavenging activity (%RSA) increased more than two times compared to the fresh G. verrucosa with a %RSA value of 16.09±6.57. Nevertheless, the highest total phenolic content of 5.62±0.00028 mg GAE/g extract was shown by G. verrucosa after 48 hours of fermentation.","PeriodicalId":21935,"journal":{"name":"Squalen Bulletin of Marine and Fisheries Postharvest and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76688870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
