Culture-independent analysis of DNA extracted from the fish flesh showed that fresh (F1) and traditional sun-dried (D2) Bombay duck exhibited little different bacterial diversity (Shannon alpha diversity 9.03 for F1 and 9.62 for D2), although the sample were collected from separate markets. <i>Rhodobacter</i> (136 OTU) and <i>Pseudomonas</i> (125 OTU) were the dominant bacteria. In contrast to fresh Bombay duck, the absence of phylum Chrysiogenetes and Caldithrix in a dry Bombay duck suggests that these gram-negative bacteria are sensitive to sun drying temperature. The co-occurrence of members of the Campylobacterales and Helicobacteraceae, as well as species of <i>Clostridium,</i><i> Arcobacter, Staphylococcus, and Streptococcus</i>, indicates the possibility of cross-contamination. Our work has led us to conclude that the association of bacteria of public health significance with densely populated urban markets makes people vulnerable to microbial threats. The study recommends an effective quality assurance program for the production of safe dry fish for domestic consumption as well as for export. </p></div>","PeriodicalId":717,"journal":{"name":"National Academy Science Letters","volume":"47 3","pages":"309 - 312"},"PeriodicalIF":1.2,"publicationDate":"2023-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134960654","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, to lessen seepage flow that travels more toward the downward side of the dam, cutoffs might be constructed. An earth dam’s footing, pore pressures in the cross–sectional area, and phreatic line, the exit gradient at the dam’s downstream face, and the potential volume of seepage flow may all be calculated using seepage analysis. In recent years, it has been normal practice to employ numerical techniques, analytical techniques, and other modeling techniques to handle the pressure of pore water and dam’s groundwater flow problems.
