Yi X, Han J, Xu X, Wang Y, Zhang M, Zhu J, He Y. Taurine-mediated gene transcription and cell membrane permeability reinforced co-production of bioethanol and Monascus azaphilone pigments for a newly isolated Monascus purpureus. BIOTECHNOLOGY FOR BIOFUELS AND BIOPRODUCTS 2024; 17:59. [PMID: 38702823 PMCID: PMC11069175 DOI: 10.1186/s13068-024-02511-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/09/2024] [Accepted: 04/26/2024] [Indexed: 05/06/2024]
Abstract
BACKGROUND Taurine, a semi-essential micronutrient, could be utilized as a sulfur source for some bacteria; however, little is known about its effect on the accumulation of fermentation products. Here, it investigated the effect of taurine on co-production of bioethanol and Monascus azaphilone pigments (MonAzPs) for a fungus. RESULTS A newly isolated fungus of 98.92% identity with Monascus purpureus co-produced 23.43 g/L bioethanol and 66.12, 78.01 and 62.37 U/mL red, yellow and orange MonAzPs for 3 d in synthetic medium (SM). Taurine enhanced bioethanol titer, ethanol productivity and ethanol yield at the maximum by 1.56, 1.58 and 1.60 times than those of the control in corn stover hydrolysates (CSH), and red, yellow and orange MonAzPs were raised by 1.24, 1.26 and 1.29 times, respectively. Taurine was consumed extremely small quantities for M. purpureus and its promotional effect was not universal for the other two biorefinery fermenting strains. Taurine intensified the gene transcription of glycolysis (glucokinase, phosphoglycerate mutase, enolase and alcohol dehydrogenase) and MonAzPs biosynthesis (serine hydrolases, C-11-ketoreductase, FAD-dependent monooxygenase, 4-O-acyltransferase, deacetylase, NAD(P)H-dependent oxidoredutase, FAD-dependent oxidoredutase, enoyl reductase and fatty acid synthase) through de novo RNA-Seq assays. Furthermore, taurine improved cell membrane permeability through changing cell membrane structure by microscopic imaging assays. CONCLUSIONS Taurine reinforced co-production of bioethanol and MonAzPs by increasing gene transcription level and cell membrane permeability for M. purpureus. This work would offer an innovative, efficient and taurine-based co-production system for mass accumulation of the value-added biofuels and biochemicals from lignocellulosic biomass.

Abstract
Diabetic ketoacidosis (DKA) is regarded to be a communal complication of both type 1 and type 2 diabetes mellitus in children and adolescents. Successful therapy of DKA in children requires prompt diagnosis, strict monitoring of medical indicators, and prompt action. Thymoquinone (Tq) from black cumin loaded chitosan nanoparticles (ChNPs) intend to assess an effective agent to overcome this problem. XRD, FTIR, SEM, and TEM were used in the physicochemical analysis. Enzymatic activity of α-amylase and α-glucosidase was used in in vitro tests of anti-diabetic efficacy. Protecting insulin against enzyme breakdown is a crucial part of the insulin delivery mechanism. In the STZ-induced diabetes RIN-5F cell line, the anti-apoptotic capability of Tq-ChNPs was demonstrated through the NF-κB mediated apoptotic pathway. The combination of thymoquinone and chitosan NPs demonstrated that a wide variety of incredibly effective substances to elevate their curative effects, thus contributing to the growth of clinical and pharmaceutical fields.

Abstract
Microbial pigments have many structures and functions with excellent characteristics, such as being biodegradable, non-toxic, and ecologically friendly, constituting an important source of pigments. Industrial production presents a bottleneck in production cost that restricts large-scale commercialization. However, microbial pigments are progressively gaining popularity because of their health advantages. The development of metabolic engineering and cost reduction of the bioprocess using industry by-products opened possibilities for cost and quality improvements in all production phases. We are thus addressing several points related to microbial pigments, including the major classes and structures found, the advantages of use, the biotechnological applications in different industrial sectors, their characteristics, and their impacts on the environment and society.
