However, the use of FM in aquafeed formulation is facing difficulties due to concerns regarding availability, price, overfishing, and sustainability. Thus, there is a growing interest in seeking alternative protein sources from plant and animal by-products to partially or fully replace FM in aquafeed. Challenges such as lower nutrient bioavailability, high antinutritional factors, indigestible materials, microbial contaminants, and lower palatability issues have limited the incorporation of these protein sources into aquafeed. The application of solid-state fermentation (SSF) strategy represents a sustainable method to address these problems by improving aquafeed quality and introducing health-promoting beneficial microbes. Moreover, numerous studies have shown that SSF enhances growth, feed utilization, health status, immune system, and disease resistance in aquaculture species. At present, molecular approaches such as transcriptomics and proteomics techniques are widely used tools for evaluating the impacts of SSF on fish and shrimp. They provide valuable insights into the mRNA transcripts and proteomes related gene expressions associated with growth, immunity, and stress response. In this article, we outline the requirements for SSF and discussed its role in ameliorating growth, health, immunity, and disease resistance in farmed species.

Thus, there is a need to find multidisciplinary, cost-effective, and potential treatment options. In parallel, the role of skin and gut microbiota has been highlighted, influencing the progression of DFU. Probiotics, when used in sufficient amounts, confer a health benefit to the host and are found to have a promising treatment potential for DFU. Probiotics exert beneficial effects that help to improve the management and healing of DFU, following various mechanisms like controlling hyperglycemia, enhancing immune function, modulating the microbiota, and maintaining glucose homeostasis, all of which contribute to improved management and healing of DFU. Despite the potential of probiotics in DFU treatment, their precise mechanisms, optimal strains, dosages, and experimental validation remain underexplored. To fully explore the probiotic potential for DFU, extensive animal studies and clinical trials are needed.

Among these, biosurfactants (BSs) and bioemulsifiers (BEs) are notable multifaceted molecules, distinguished by their unique structural, molecular, and functional properties. Marine yeasts and fungi produce BSs/BEs with distinctive properties in terms of stability under extreme conditions. It is important to mention here that in comparison to marine bacteria, yeast and fungi of the same habitat have been explored only intermittently. Some of the BSs/BEs producing bacteria may prove to have some pathogenic or cytotoxic traits or components, while most yeasts are mainly classified as Generally Recognized As Safe (GRAS) (by the Food and Drug Administration-FDA, USA), making their BSs/BEs products more amenable for a wide range of applications. The diverse and unique potential of surface-active agents is further enhanced by the endosymbiotic associations often found in marine yeasts and fungi. These microorganisms are acknowledged to produce glycolipidic (rhamnolipids, sophorolipids, and mannosylerythritol lipids) or glycolipoproteins. The SL have been reported well for their strong antimicrobial activity, including effectiveness against drug-resistant pathogens, making them promising candidates for controlling foodborne pathogens in the food industry. Furthermore, these microorganisms can utilize a broad range of carbon sources from simple substrates, like glucose and glycerol, to complex feedstocks such as food, oil, agricultural waste, and wastewater, which not only support their growth but also promote the production of substantial yields of these BSs/BEs. In this review, we endeavor to explore BSs/BEs from marine yeasts and fungi, including the screening, characterization, identification, production, and importance.</p>","PeriodicalId":46108,"journal":{"name":"AIMS Microbiology","volume":"11 3","pages":"542-573"},"PeriodicalIF":4.1,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12511957/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145281285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
