This study used molasses and tuna condensate as low-cost carbon and nitrogen sources in the medium (MLFC) for fungal chitin production. Through screening, <em>Trichoderma asperellum</em> was selected as the test strain. MLFC yielded biomass (10.40 g/L), and acid-insoluble material (AAIM) (3.96 g/L) comparable to those from a glucose basal medium (GBM), while it gave acid-soluble material (AASM) 2.52-fold more than GBM. MLFC also provided industrially useful enzymes such as xylanase and protease. FTIR and XRD analyses showed that AAIM samples from MLFC (T-AAIM-MLFC) and GBM (T-AAIM-GBM) had similar structural properties, but these were slightly different from commercial chitin. Component analysis of acid hydrolysate indicated tentatively that they were chitin-glucan complex. T-AAIM-MLFC displayed degree of acetylation of 67.43 % with crystallinity index of 50.42 %. Interestingly, the AASM from MLFC (T-AASM-MLFC) showed FTIR and XRD spectral patterns distinct from those of chitosan and GBM-derived AASM (T-AASM-GBM). FESEM-EDX revealed that it presented a granule structure with high P and Ca contents unlike the T-AASM-GBM that had a smooth surface of nanofibers with some porosity. Further, T-AASM-MLFC showed FTIR and XRD spectral patterns closely similar to hydroxyapatite.

However, current recovery methods from soybean oil deodorizer distillate (SODD) remain limited, as conventional techniques often rely on solvents, exhibit low selectivity, or require long processing times. Studies specifically addressing membrane-based valorization of SODD are still scarce. This study proposes an integrated and cleaner production approach for squalane recovery from SODD, a byproduct rich in unsaponifiable compounds. The methodology combines a saponification pretreatment with intermediate centrifugation and membrane microfiltration to enhance selectivity and mitigate membrane fouling. The results demonstrated that increasing the potassium hydroxide concentration to 20% during saponification significantly improved membrane selectivity. The integration of centrifugation before microfiltration further enhanced squalane recovery, yielding a squalane concentration in the permeate of 174.03 ± 2.43 mg 100 g sample<sup>−1</sup>, which was approximately thirteen times higher compared to the retentate. This value represents the recovery yield achieved by the developed process. Therefore, the time required for squalane recovery in this study is about six times shorter, representing a significant advantage, even though the final concentration is lower. Overall, this membrane-based strategy proved to be an efficient, rapid, and solvent-free alternative for squalane recovery from SODD, promoting industrial byproduct valorization and aligning with circular economy principles and Sustainable Development Goal 12 on responsible production and consumption.</div></div>","PeriodicalId":8947,"journal":{"name":"Bioresource Technology Reports","volume":"33 ","pages":"Article 102610"},"PeriodicalIF":0.0,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146073574","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}
