Sustainable biorefinery approach by utilizing xylose fraction of lignocellulosic biomass. Int J Biol Macromol 2024; 266:131290. [PMID: 38569993 DOI: 10.1016/j.ijbiomac.2024.131290] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2023] [Revised: 03/20/2024] [Accepted: 03/29/2024] [Indexed: 04/05/2024]
Abstract
Lignocellulosic biomass (LCB) has been a lucrative feedstock for developing biochemical products due to its rich organic content, low carbon footprint and abundant accessibility. The recalcitrant nature of this feedstock is a foremost bottleneck. It needs suitable pretreatment techniques to achieve a high yield of sugar fractions such as glucose and xylose with low inhibitory components. Cellulosic sugars are commonly used for the bio-manufacturing process, and the xylose sugar, which is predominant in the hemicellulosic fraction, is rejected as most cell factories lack the five‑carbon metabolic pathways. In the present review, more emphasis was placed on the efficient pretreatment techniques developed for disintegrating LCB and enhancing xylose sugars. Further, the transformation of the xylose to value-added products through chemo-catalytic routes was highlighted. In addition, the review also recapitulates the sustainable production of biochemicals by native xylose assimilating microbes and engineering the metabolic pathway to ameliorate biomanufacturing using xylose as the sole carbon source. Overall, this review will give an edge on the bioprocessing of microbial metabolism for the efficient utilization of xylose in the LCB.

Abstract
Microbial cell factories, renowned for their economic and environmental benefits, have emerged as a key trend in academic and industrial areas, particularly in the fermentation of natural compounds. Among these, plant-derived terpenes stand out as a significant class of bioactive natural products. The large-scale production of such terpenes, exemplified by artemisinic acid-a crucial precursor to artemisinin-is now feasible through microbial cell factories. In the fermentation of terpenes, two-phase fermentation technology has been widely applied due to its unique advantages. It facilitates in situ product extraction or adsorption, effectively mitigating the detrimental impact of product accumulation on microbial cells, thereby significantly bolstering the efficiency of microbial production of plant-derived terpenes. This paper reviews the latest developments in two-phase fermentation system applications, focusing on microbial fermentation of plant-derived terpenes. It also discusses the mechanisms influencing microbial biosynthesis of terpenes. Moreover, we introduce some new two-phase fermentation techniques, currently unexplored in terpene fermentation, with the aim of providing more thoughts and explorations on the future applications of two-phase fermentation technology. Lastly, we discuss several challenges in the industrial application of two-phase fermentation systems, especially in downstream processing.

Abstract
Limonene is a volatile monoterpene compound that is widely used in food additives, pharmaceutical products, fragrances, and toiletries. We herein attempted to perform efficient biosynthesis of limonene in Saccharomyces cerevisiae using systematic metabolic engineering strategies. First, we conducted de novo synthesis of limonene in S. cerevisiae and achieved a titer of 46.96 mg/L. Next, by dynamic inhibition of the competitive bypass of key metabolic branches regulated by ERG20 and optimization of the copy number of tLimS, a greater proportion of the metabolic flow was directed toward limonene synthesis, achieving a titer of 640.87 mg/L. Subsequently, we enhanced the acetyl-CoA and NADPH supply, which increased the limonene titer to 1097.43 mg/L. Then, we reconstructed the limonene synthesis pathway in the mitochondria. Dual regulation of cytoplasmic and mitochondrial metabolism further increased the limonene titer to 1586 mg/L. After optimization of the process of fed-batch fermentation, the limonene titer reached 2.63 g/L, the highest ever reported in S. cerevisiae.
