Current advances in microbial production of 1,3‐propanediol

Abstract: 1,3‐Propanediol (1,3‐PDO), an important chemical raw material, has attracted much attention due to its wide use as a monomer of biodegradable polyester materials. Production of 1,3‐PDO from renewable resources, through microbial fermentation, has the advantage of requiring only mild conditions. The process also demonstrates industrial safety and is environmentally friendly. In this review, we have summarized and commented on current progress in screening and breeding strains for 1,3‐PDO production, especially … Show more

“…Even though the average titer is reduced (85.0 g/L), it benefits the up-scale fermentation by reducing time of seed cultivation and improving stability of 1,3-PDO production. The yield of 1,3-PDO production from fed-batch fermentation of glycerol reported to our knowledge mostly ranges from 0.45 to 0.58 g 1,3-PDO /g Gly , indicating the favorable mode of operation for up-scale production [135,140,141].…”

“…The open mixed culture (MMC) technology is also receiving attention due to the advantage in non-sterile fermentation, which is favorable for the up-scale production, as it could reduce costs related to sterilization and pure feedstock requirements and enhance tolerance to feedstock and by-product (e.g., organic acid) toxicity [141]. Varrone et al reported the potential continuous anaerobic fermentation of crude glycerol to 1,3-PDO by enriched anaerobic sludge at pH 5.5 and with a retention time of 12 h. Crude glycerol concentration could be increased to almost 90 g/L, but the maximum substrate conversion rate (94%) was observed at a concentration around 50-60 g/L, using an animal fat-derived crude glycerol.…”

“…Além disso, o 1,3-PDO é utilizado na fabricação de poli tereftalato de etileno (PET), um plástico biodegradável, cuja produção apresenta perspectivas de expansão. Atualmente, o 1,3-PDO é majoritariamente produzido quimicamente (ZHU et al, 2021) por hidratação de acroleína, hidroformilação de óxido de etileno e transformação enzimática do glicerol (LEE et al, 2015). No entanto, a biossíntese do glicerol foi sugerida pela primeira vez há 140 anos como um método de produção de 1,3-PDO (FREUND, 1881).…”

“…No entanto, a biossíntese do glicerol foi sugerida pela primeira vez há 140 anos como um método de produção de 1,3-PDO (FREUND, 1881). Além da fermentação ser um método de obtenção de produtos mais sustentável do que a fabricação química, no contexto atual, a produção de 1,3-PDO a partir do glicerol está associada ao aumento da valorização do biodiesel (SUN et al, 2018;ZHU et al, 2021), uma vez que, estima-se que os preços anuais do 1,3-PDO aumentem em até 14,2% ao ano até 2027 (ZHU et al, 2021).…”
