However, the microorganisms and chemical changes involved during this fermentation process are unknown. The objectives of this research were to identify the cultivable and non-cultivable microorganisms involved during this fermentation using PCR, PCR-DGGE, and the sequencing of the 16S and 18S ribosomal genes, and to determine the chemical changes that occur throughout the fermentation process. Results showed the presence of 28 microorganisms during the sotol (Dasylirion durangensis) production which corresponded to Bacillus, Lactobacillus, Kluyveromyces and Pichia genera, with the major-species richness, occurring in the dry fermentation stage. On the 7th day of fermentation, 80% of total sugar was consumed. While, on the 10th day of fermentation, the highest (96%) consumption of total sugar and the highest (9.5% v/v) ethanol concentration were observed. During this stage of fermentation, most of the microorganisms isolated belonged to Lactobacillus, Bacillus, and Kluyveromyces genera. Like in the production of mescal and tequila, on the 10th day of fermentation, the presence of organic compounds such as isoamyl acetate, isoamyl alcohol, limonene, and 2-phenylethanol was confirmed. The knowledge gathered about the microorganisms and chemical changes involved during sotol production could help to standardize the process for obtaining a beverage with organoleptic characteristics desirable to consumers.","PeriodicalId":12347,"journal":{"name":"Food Biotechnology","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2021-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/08905436.2020.1869981","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42757515","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}

This review summarizes the current trend in the biotechnologically-derived vanillin bioconversion from agricultural byproducts rich in eugenol, ferulic acid, isoeugenol, lignin, and de novo synthesis by bacteria, fungi, and recombinant microbial cells. This review also outlines the enzymes involved in vanillin synthesis. The subsequent section deals with the cultural conditions needed for the enhanced production of vanillin. This review offers broad knowledge about the downstream processes such as isolation, characterization, purification, and recovery.

Diamine oxidase (DAO) has found important utility in food and allied industries for protection of food freshness and safety. In this study, an activated PVC strip was developed, covalently immobilized to purified DAO from pea seedlings. A comparative investigation was done on the parameters affecting catalytic activity of the free and immobilized enzyme, such as pH, temperature, and enzyme concentration. The immobilization preserved 81% of the initial enzyme activity against the substrate, putrescine dihydrochloride. The optimal pH levels of free and immobilized DAO were 7.0 and 6.5, respectively. The highest activity of the immobilized DAO was observed at 40°C while 34°C for the free enzyme. Moreover, the immobilized DAO retained about 52% of its initial activity after 10 repetitive uses and the activity was maintained after 30 days at 4°C. Therefore, this strategy may provide an excellent support for enzyme immobilization having better catalytic ability and operational stability than its free counterpart. Eventually, the results observed can be used further for various applications such as in food industry, to evaluate the freshness of real samples, and in biotechnological field to fabricate specific biosensors to detect biogenic amines content for evaluating food hygienic quality. Thus, the prepared enzyme catalyst presents a new approach for successful industrial applications.","PeriodicalId":12347,"journal":{"name":"Food Biotechnology","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/08905436.2020.1833912","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43908760","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}

Many hydrolysates from G. lucidum exhibit various biological functions. Using LC-MS/MS, the peptide sequence was predicted based on the de novo sequencing algorithm and P1-peptide (VDLPTCKGF) was identified. The peptide was modified by shortening C-terminal residue one at a time until three residues remained, and chemically synthesized all modified peptides by SPPS. Seven-synthetic peptides were purified and molecularly evaluated by HPLC and LC-MS. The antioxidant capacity of these peptides was evaluated, while also the intracellular-ROS was detected to validate the antioxidant activity. This study showed that 3 of 7 synthetic peptides had in vitro antioxidant activity and suppressed intracellular-ROS. Among all modified peptides, VDLPTC exhibited the highest antioxidant capacity and revealed intracellular-ROS suppression. This evidence reflects their radical-scavenging activities and provides the rationale for the development of novel functional food ingredients.","PeriodicalId":12347,"journal":{"name":"Food Biotechnology","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/08905436.2020.1844228","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49549143","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}

The impact of fermentation of multi-grain-based food on proximate composition, antinutrients, and antioxidants was evaluated. Fermented product showed significant increments (P <.05) in protein (13.6%) and fiber (1.8%) content. Moreover, the rapidly digestible starch (27.5%) and resistant starch (15.0%) levels were found to increase significantly (P <.05) while the slowly digestible starch level decreased (87.7%) in the fermented food sample. After 4 days of fermentation, total phenolic and total flavonoid contents increased by 83.0% and 69.8%, respectively, with a greater antioxidant potential of 85.9%. The fermented food sample showed a significant reduction in the phytate (64.5%) and trypsin inhibitor activity (19.9%) (P <.05) with a substantial increase in phytase level (P <.05). Fourier transform infrared spectroscopy clearly revealed the alteration of physico-chemical properties during fermentation with S. cerevisiae AKP1. Gas chromatography–mass spectrometry analysis detected the presence of 38 volatile compounds in the fermented food material with the prevalence of fatty acids such as palmitic acid, linoleic acid, among others; alcohols such as isoamyl alcohol, 2,3-butanediol, among others; and esters such as ethyl-2-methylbutanoate.

YH exhibited strong ACE inhibitory activity, with IC50 value of 26.13 μg/mL, while antihypertensive properties were found on spontaneously hypertensive rats (SHRs) in short- and long-term administrations.

Endophytic bacteria were isolated from the coconut fruit endosperm – both, from liquid and flesh sources. Morphological and biochemical characterization was carried out for the isolates and were screened for antibacterial activity. Further, the effective isolate was mass multiplied, the metabolites synthesized by the isolate were extracted and the presence of compounds such as stigmasterol, oleic acid, and palmitic acid (2-Phenyl-1,3-Dioxolan-4-yl) methyl ester were identified by Gas chromatography–mass spectrometry analysis and were confirmed with Fourier-transform infrared spectroscopy. Scanning electron microscope images revealed the presence of microbial cells in the endoderm flesh. The isolate VITKUJ4 was identified to be the closest neighbor of Staphylococcus cohnii upon 16S rRNA gene sequencing and phylogenetic analysis.
