“…Clostridium beijerinckii is a Gram-positive anaerobic solventogenic bacterium that is well known for its ability to produce acetone, butanol, and ethanol (ABE) or isopropanol, butanol, and ethanol (IBE) ( Qureshi and Blaschek 2001 ; Survase et al 2011 ; dos Santos Vieira et al 2020 ) using low-cost carbon sources, such as different straw hydrolysates ( Bellido et al 2014 ; Dalal et al 2019 ), lignocellulosic hydrolysate ( Reddy et al 2020 ), and molasses ( Li et al 2013 ; Fonseca et al 2020 ). In addition, it has been used to produce hydrogen with great success ( Seelert et al 2015 ).…”

Clostridium beijerinckii is a well-known anaerobic solventogenic bacterium which inhabits a wide range of different niches. Previously, we isolated five butyrate-producing C. beijerinckii strains from pit mud (PM) of strong-flavor baijiu (SFB) ecosystems. Genome annotation of the five strains showed that they could assimilate various carbon sources as well as ammonium to produce acetate, butyrate, lactate, hydrogen, and esters but did not produce the undesirable flavours isopropanol and acetone, making them useful for further exploration in SFB production. Our analysis of the genomes of an additional 233 C. beijerinckii strains revealed an open pangenome based on current sampling and will likely change with additional genomes. The core genome, accessory genome, and strain-specific genes comprised 1567, 8851, and 2154 genes, respectively. A total of 298 genes were found only in the five C. beijerinckii strains from PM, among which only 77 genes were assigned to Clusters of Orthologous Genes (COG) categories. In addition, 15 transposase and 12 phage integrase families were found in all five C. beijerinckii strains from PM. Between 18 and 21 genome islands (GIs) were predicted for the five C. beijerinckii genomes. The existence of a large number of MGEs indicated that the genomes of the five C. beijerinckii strains evolved with the loss or insertion of DNA fragments in the PM of SFB ecosystems. This study presents a genomic framework of C. beijerinckii strains from PM that could be used for genetic diversification studies and further exploration of these strains.

“…In moist conditions, the long chains of large molecules which make up polymers are broken down by water molecules, causing the polymers to slowly degrade, which is known as "hydrolysis" [31][32][33]. Hydrocarbon polymers are generally stable to water, and the water content is very low when they reach equilibrium in the aqueous solution.…”

With the flourishment of the polymer industry, many polymers have been produced and used. However, it has been acerbically criticized that most of the polymers, such as polyolefins, polyesters, cannot be naturally degraded or depolymerized, leading to polymer waste, which has exacerbated the growing global contamination. Therefore, it is essential to research and ameliorate depolymerization methods to diminish the polymer waste and recycle them. This article reviews a series of novel depolymerization methods in recent years, including pyrolysis, ionic liquids, hydrolysis, and biological methods, aiming to depolymerize the waste polymer with heteroatom-containing main chain, such as poly (ethylene terephthalate), polyamides, polyesters. The mechanisms and applications of these depolymerization methods are highlighted. Although traditional pyrolysis methods have relatively low yield, selectivity, and harsh conditions, some catalytical pyrolysis methods have better selectivity, energy consumption, etc. Besides, due to the good recyclability of ionic liquids, an excellent yield of monomers, and relatively moderate conditions, ionic liquids have been widely used in depolymerizing the polymers with heteroatom-containing main chain, which are processing a stepwise ionic depolymerization mechanism. Moreover, because water is economical and environmentally friendly, depolymerization via hydrolysis is also worthy of research. Finally, some biological methods are prevailing because of their high selectivity, high efficiency, and mild conditions, although the mechanisms are still obscure that there have been only a few uniform theories, such as oxidizing-degrading mechanism, hydrolysis mechanism.

“…DF is a light-independent process that involves the anaerobic conversion of a complex substrate into a simpler product through the use of facultative and obligate anaerobe fermentation. Microorganisms of the genus Clostridium are primarily used in the dark fermentation of algae to produce hydrogen [ 11 , 26 , 27 , 37 , 38 , 39 , 40 , 41 , 42 ]. Table 2 shows that microorganisms from the genera Enterobacteriaceae, Acinetobacter, Terrisporobacter, Paraclostridium, Anaerostipes, and Caproiciproducens also participate in hydrogen fermentation of algae [12] .…”
