By evaluating and selecting appropriate media and substrates, the production of bacterial cellulose can be more efficient: enabling sustainable systems and supply chains where less energy and materials are lost, and the output production is increased. The purpose of this paper is to analyze the current landscape of bacterial cellulose alternative media and substrates (ingredients). Through a systematic review of 198 papers, this review identifies 299 alternative substrates from 12 industries and 101 bacterial cellulose-producing strains, which were systematically compared. This review also finds that there are methodological gaps in this field such as data variability, papers mislabelling the HS media or not using a comparison media, and a lack of strain names. This alternative substrate analysis for bacterial cellulose production demonstrates that overall, for some applications alternative substrates can be taken into consideration that are not only cheaper, but also produce higher yields than HS media.</div></div>","PeriodicalId":52344,"journal":{"name":"Journal of Bioresources and Bioproducts","volume":"9 4","pages":"Pages 379-409"},"PeriodicalIF":20.2,"publicationDate":"2024-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142530107","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}

In this study, the laws and mechanism of mechanical properties of MFP with ambient temperature, humidity and MC were studied. The results showed that the direct effect of temperature (20−70 °C) on mechanical properties of MFP was insignificant, and the mechanical properties of MFP were mainly changed by MC. The MC was related to ambient temperature and humidity, and the relationship between the three could be described by the modified Guggenheim-Anderson-de Boer (GAB) model (20−70 °C and 30 %–90 % relative humidity). With the increase of MC, the elastic modulus and fracture strain was increased and decreased linearly, the yield strength and failure strength were presented GaussAmp laws, and the failure strain was presented asymptotic regressed distribution law. Two fracture modes of MFP, brittle fracture and ductile fracture, were revealed by the scanning electron microscopy of the mesoscopic fiber structure of sugarcane bagasse molded fiber products.

Bacterial load as well as laccase and manganese peroxidase enzyme activity profile assay during the retting duration were analyzed. Fourier transform infrared (FT-IR) and X-day diffraction (XRD) analyses were also examined for both pre-treated and untreated extracted fibers. The results shows that six out of the eight bacterial isolates had the ability to degrade lignin.

In addition, the increased roughness of chitosan pore walls by embedded silk microfibers significantly promoted cell adhesion and proliferation.
