Abstract
Clostridium fermentations have been developed for producing butanol and other value-added chemicals, but their development is constrained by some limitations, such as relatively high substrate cost and the need to maintain an anaerobic condition. Recently, co-culture is emerging as a popular way to address these limitations by introducing a partner strain with Clostridium. Generally speaking, the co-culture strategy enables the use of a cheaper substrate, maintains the growth of Clostridium without any anaerobic treatment, improves product yields, and/or widens the product spectrum. Herein, we review recent developments of co-culture strategies involving Clostridium species according to their partner stains' functions with representative examples. We also discuss research challenges that need to be addressed for the future development of Clostridium co-cultures.

Abstract Microbial fermentation of synthesis gas (syngas) is becoming more attractive for sustainable production of commodity chemicals. To date, syngas fermentation focuses mainly on the use of Clostridium species for the production of small organic molecules such as ethanol and acetate. The co-cultivation of syngas-fermenting microorganisms with chain-elongating bacteria can expand the range of possible products, allowing, for instance, the production of medium-chain fatty acids (MCFA) and alc...

Synthetic microbial consortia could efficiently produce biofuels from lignocellulose through labor division between different species. However, the incompatible growth conditions between lignocellulose degraders and biofuel producers might limit the overall conversion efficiency. We discuss recent examples of biofuel production using microbial consortia and suggest steps toward realistic implementation.

Metal halide perovskites have emerged as promising candidates for solution-processed blue light-emitting diodes (LEDs). However, halide phase segregation – and the resultant spectral shift – at LED operating voltages hinders their application. Here we report true-blue LEDs employing quasi-two-dimensional cesium lead bromide with a narrow size distribution of quantum wells, achieved through the incorporation of a chelating additive. Ultrafast transient absorption spectroscopy measurements reveal ...

: Production of esters from the acetone-butanol-ethanol (ABE) fermentation by Clostridium often focuses on butyl butyrate, leaving acetone as an undesired product. Addition of butyrate is also often needed because ABE fermentation does not produce enough butyrate. Here we addressed the problems using Clostridium beijerinckii BGS1 that preferred to produce isopropanol instead of acetone, and co-culturing it with Clostridium tyrobutyricum ATCC 25,755 that produced butyrate. Unlike acetone, isoprop...

Abstract An engineered B. subtilis 1A1 strain (BsADH2) expressing a secondary alcohol dehydrogenase (CpSADH) was co-cultured with C. beijerinckii G117 under an aerobic condition. During the fermentation on glucose, B. subtilis BsADH2 depleted oxygen in culture media completely and created an anaerobic environment for C. beijerinckii G117, an obligate anaerobe, to grow. Meanwhile, lactate produced by B. subtilis BsADH2 was re-assimilated by C. beijerinckii G117. In return, acetone produced by C. ...

Abstract Butanol production from lignocelluloses is desirable. Unfortunately, the known wild-types of butanol fermenting Clostridium bacteria are not capable of delignification and saccharification. Here we analyzed butanol production from cellulosic material using anaerobic co-culture of C. saccharoperbutylacetonicum with the white-rot fungus Phlebia sp. MG-60-P2. In consolidated bioprocessing, the co-culture synergistically produced butanol and enhanced saccharification. Knockout of the pyruva...

Synthetic microbial communities have become a focus of biotechnological research since they can overcome several of the limitations of single-specie cultures. A paradigmatic example is Clostridium cellulovorans DSM 743B, which can decompose lignocellulose but cannot produce butanol. C. beijerinckii NCIMB 8052 however, is unable to use lignocellulose but can produce high amounts of butanol from simple sugars. In our previous studies, both organisms were co-cultured to produce butanol by consolida...

Most mono- and co-culture bioprocess applications rely on large-scale suspension fermentation technologies that are not easily portable, reusable, or suitable for on-demand production. Here, we describe a hydrogel system for harnessing the bioactivity of embedded microbes for on-demand small molecule and peptide production in microbial mono-culture and consortia. This platform bypasses the challenges of engineering a multi-organism consortia by utilizing a temperature-responsive, shear-thinning ...

Clostridium acetobutylicum is widely used for the microbial production of butanol in a process known as acetone-butanol-ethanol (ABE) fermentation. However, this process suffers from several disadvantages including high oxygen sensitivity of the bacterium which makes the process complicated and necessitate oxygen elimination in the culture medium. Nesterenkonia sp. strain F has attracted interests as the only known non-Clostridia microorganism with inherent capability of butanol production even ...

Bio-catalytic processes for sustainable production of chemicals and fuels receive increased attention within the concept of circular economy. Strategies to improve these production processes include genetic engineering of bio-catalysts or process technological optimization. Alternatively, synthetic microbial co-cultures can be used to enhance production of chemicals of interest. It remains often unclear however how microbe to microbe interactions affect the overall production process and how thi...

Abstract null null In times of global warming and upcoming fossil fuel shortages, the demand for the replacement of current fossil fuel-based chemical production via the development of alternative technologies and sustainable resources has increased. As a possible solution, an approach that produces chemicals from C1 gases derived from industrial waste gas or syngas has been suggested, but inefficient costs and syngas contaminant-sensitive processes of chemical catalysts have limited C1 gas util...
