Isopropanol-butanol production from sugarcane and sugarcane-sweet sorghum juices by Clostridium beijerinckii DSM 6423

Phenotypic and genomic analysis of isopropanol and 1,3-propanediol producer Clostridium diolis DSM 15410

“…Secondly, ability to utilize glycerol and produce 1,3-propanediol and isopropanol in glucose medium was again confirmed for C. diolis DSM 15410, which was not observed for the two tested C. beijerinckii strains. Nevertheless, these abilities were observed for other C. beijerinckii strains, such as, 1,3-propanediol production by type strain C. beijerinckii DSM 791 [65] or isopropanol production by C. beijerinckii DSM 6423 or C. beijerinckii BGS1 [48,66]. Observable growth of two C. beijerinckii strains was surprisingly detected in RCM medium containing glycerol.…”

Lowering whole cost for sugarcane‐based ethanol production by engineered Zymomonas mobilis

“…Sugars (sucrose, glucose, and fructose) of SCJ were analyzed by high-performance liquid chromatography (HPLC, see Section 2.5.2). For convenience, total sugar was presented with glucose equivalents (total sugar = glucose + fructose + 1.05 × sucrose; Rochon et al, 2019). Besides, the content of mineral elements in SCJ was determined by inductively coupled plasma (ICP, PlasmaQuant 9000).…”

Bioprocess intensification for isopropanol, butanol and ethanol (IBE) production by fermentation from sugarcane and sweet sorghum juices through a gas stripping-pervaporation recovery process

“…Isopropanol is an important commodity chemical with a variety of applications and the solvent mixture produced by fermentation (IBE) can be used as a fuel [4][5][6]. The microorganism best known as natural IBE producer is Clostridium beijerinckii DSM 6423 [3,4,7,8].…”

“…Major challenges in biobutanol production are the cost of the raw material and the intensive energy consumption in product recovery stages of the entirely IBE production process [9][10][11]. Sugarcane and sweet sorghum are crops whose juices contain high amounts of soluble fermentable sugars, and many essential nutrients for microbial growth [8,12]. Both, mainly sugarcane, are currently used for fuel bioethanol production in Uruguay.…”
