AbstractErythritol is a four-carbon sugar alcohol naturally produced by microorganisms as an osmoprotectant. As new substitute, erythritol has recently been popular on the ingredient market because of its unique nutritional characteristics. Even though history biosynthesis dates from turn twentieth century, scientific advancement lagged behind other polyols due to relative complexity making it. In recent years, biosynthetic methods for have rapidly developed increase in demand, better understanding metabolic pathways, and rapid development genetic engineering tools. This paper reviews industrial strain focuses underlying mechanism high production strains gained through screening or mutagenesis. Meanwhile, we highlight pathway knowledge summarize research progress critical genes involved different stages synthetic pathway. Lastly, talk about still-contentious issues promising future directions that will help break bottleneck make greener more sustainable.Keywords: Erythritolindustrial biotechnologymetabolic pathwayserythrose reductasetransketolaseYarrowia lipolytica AcknowledgmentsWe also thank PhD student Mingjing Yao her selfless submitting manuscript proofreading formatting.Disclosure statementNo potential conflict interest was reported author(s).Additional informationFundingThe author(s) appreciate financial support Natural Science Foundation Shandong Province (C010303) Major Innovation Pilot Project Integration Science, Education, Industry Qilu University Technology (Shandong Academy Science) (2022JBZ01-08).

d-Allulose, a functional bulk sweetener, has recently attracted increasing attention because of its low-caloric-ness properties and diverse health effects. d-Allulose is industrially produced by the enzymatic epimerization d-fructose, which catalyzed ketose 3-epimerase (KEase). In this study, food-grade expression KEase was studied using Bacillus subtills as host. Clostridium sp. d-allulose (Clsp-DAEase) screened from nine d-allulose-producing KEases, showing better potential for in B. WB600. Promoter-based transcriptional regulation N-terminal coding sequence (NCS)-based translational were to enhance DAEase level. addition, synergistic effect promoter NCS on Clsp-DAEase studied. Finally, strain with combination PHapII gln A-Up selected best Clsp-DAEase-producing strain. It efficiently total activity 333.2 1860.6 U/mL shake-flask fed-batch cultivations, respectively.

Host-microbe interactions underlie the development and fitness of many macroorganisms, including bees. Whereas social bees benefit from vertically transmitted gut bacteria, current data suggests that solitary bees, which comprise vast majority species diversity within lack a highly specialized microbiome. Here, we examine composition abundance bacteria fungi throughout complete life cycle ground-nesting bee Anthophora bomboides standfordiana. In contrast to expectations, immature stages maintain distinct core microbiome consisting Actinobacterial genera (Streptomyces, Nocardiodes) fungus Moniliella spathulata. Dormant (diapausing) larval hosted most abundant distinctive fungi, attaining 33 52 times their initial copy number, respectively. We tested two adaptive hypotheses regarding microbial functions for diapausing First, using isolated found Streptomyces brood cells inhibited growth multiple pathogenic filamentous suggesting role in pathogen protection during overwintering, when face high pressure. Second, sugar alcohol changed tandem with major changes fungal abundance, links cold tolerance or overwintering biology. find A. hosts conserved may provide key advantages through diapause, raises question how this is maintained faithfully between generations. Our results suggest focus on microbiomes mature active insect developmental overlook stage-specific symbionts contributions host dormancy.
