After cellulase treatment, each by-product was separated into ethanolic extract (EEC) and alcohol insoluble fiber (AIF). Cellulase treatment led to the dissolution of the insoluble fiber in all the by-products. Subsequently, the molecular weight distribution and prebiotic activity of the EEC were determined. All cellulase-treated by-products showed a shift from high to low in molecular weight distribution, with a higher prebiotic activity score. Cellulase treatment also affected the microstructure, crystallinity index, and chemical bonds in AIF as observed through Scanning Electron Microscope, X-ray crystallography analysis, and Fourier-transform Infrared spectra analysis. The structural lattice changes manifested as an improved capacity in binding bile acids. Cellulase treatment is a feasible method to unleash the recalcitrant nature of guava by-products.","PeriodicalId":12347,"journal":{"name":"Food Biotechnology","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2022-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138512417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, 26 lactic acid bacteria (LAB) isolated from laboratory-scale coffee fermentation were screened for their capacity to preferentially consume fructose over glucose and identified by 16S rDNA sequencing. Ten fructose-consuming isolates were identified as Levilactobacillus brevis (n = 8) and Pediococcus pentosaceus (n = 2). The growth characteristics of three Lev. brevis strains (LPBF01, LPBF03 and LPBF06) were classified as “facultatively” fructophilic bacteria, i.e., they grew on glucose without an external electron acceptor (oxygen, fructose, or pyruvate) but grew more rapidly on fructose. Lev. brevis LPBF03 was characterized for producing a high content of flavor-active esters (1-butanol, benzaldehyde, 2-nonenal, and 2-pentanone) and now being targeted as a good candidate to improve fructose consumption and aroma formation during coffee fermentation.","PeriodicalId":12347,"journal":{"name":"Food Biotechnology","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2022-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45147226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, 300 LAB were isolated from different sources and screened for antifungal activity in vitro against 9 spoilage fungi. Moreover, the most active strain Lactiplantibacillus pentosus 22B was utilized in yogurt as a biopreservative against fungal spoilage. Characterization of the antifungal compounds based on fungal response to concentrated extract after enzymatic treatments, GC-MS, and headspace GC-MS showed that L. pentosus 22B potentially produced a variety of active compounds including organic acids, peptidic compounds, fatty acids, volatile compounds, and hydrogen peroxide. The application of cell free-supernatant produced by L. pentosus 22B in yogurt showed its ability to prevent fungal growth during 22 days at 25°C. This LAB strain is a potential candidate for yogurt biopreservation based on the antifungal activity of L. pentosus in yogurt which has been experimentally confirmed for the first time.","PeriodicalId":12347,"journal":{"name":"Food Biotechnology","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2021-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45097395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, flesh of nectarine (Shuguang) was used to determine the difference in transcriptional data before and after chilling injury under storage. In addition, genes responses involved in nectarine acclimation to cold stress were also explored. Results of the current study showed that nectarine was found to be more susceptible to chilling injury during storage at 5°C than at 0°C, and differentially expressed genes (DEGs) were concentrated in the late stage of low-temperature storage where chilling injury symptoms appeared at the end of the experiment. The key genes related to low-temperature response were associated with post-harvest biological processes. DEGs were annotated on the metabolic pathways of cold regulation signal transduction, cold resistance physiological metabolism and cold resistance-related protein synthesis. Moreover, the expression of genes related to cold stress such as plant hormone signal transduction element such as Auxin-responsive protein, transcription factors responding to cold stress such as WRKY transcription factor and genes related to maintaining membrane stability and regulating physiological metabolism such as proline dehydrogenase was more pronounced when nectarine was stored at 5°C than at 0°C. Overall, these findings showed that alteration in chilling temperature has substantial impact on the transcription levels associated with cold resistance pathway during the low-temperature storage of nectarine and thus promotes chilling injury disorders in nectarine.","PeriodicalId":12347,"journal":{"name":"Food Biotechnology","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2021-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43881119","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the risk of antibiotics to food safety, it is banned for use in resistance screening with food-grade expression system. Therefore there merit and value in exploring the use of Aspergillus oryzae food-grade expression system based on auxotrophic markers. In this study uridine/uracil auxotrophic strains A. oryzae RIB40ΔpyrG were generated by ultraviolet mutagenesis of pyrG gene deletion which would then be used as a host for further transformation analysis and applications. Meanwhile, a novel and efficient expression vector pBC-hygro.4 was constructed, which included the pyrG cassette gene, His-Tag, amyB promoter and terminator, and green fluorescent protein GFP marker. pBC-hygro.4 was successfully transferred to A. oryzae RIB40ΔpyrG via the PEG-CaCl2-mediated transformation method, and the stability of pBC-hygro.4 was evaluated by detecting the expression of the GFP reporter gene. Through phenotyping and sequencing verification, a uridine/uracil auxotrophic strains A. oryzae RIB40ΔpyrG were successfully generated. In addition, the developed vectors were fully functional for heterologous expression of the GFP fluorescent proteins in A. oryzae RIB40ΔpyrG and the recombinant A. oryzae RIB40ΔpyrG cultures indicated pronounced green fluorescence in the mycelia. Based on auxotrophic/nutritional markers, this study provides an effective method that can be applied to develop similar fungal transformation systems in other filamentous fungi, which will be beneficial for food-grade applications.","PeriodicalId":12347,"journal":{"name":"Food Biotechnology","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2021-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44333223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
