Summary: There is an urgent need worldwide to develop novel therapeutics to combat antibiotic-resistant superbugs. Enzymes in the branched-chain amino acid (BCAA) biosynthesis pathway are attractive targets for the development of new antimicrobial drugs. Recent research has focused on dihydroxy-acid dehydratase (DHAD), the third enzyme in the BCAA biosynthesis pathway, which has shown catalytic activity in cell-free enzyme cascades. In this study, researchers characterized DHADs from two bacterial human pathogens and identified potential inhibitors that could be used as starting points for the development of new antimicrobial chemotherapeutics.

Summary: Facing increasing mobility, energy demand, and the need to mitigate climate change, developing sustainable and eco-friendly alternatives to fossil fuels is a crucial task for humanity. Biofuels and synthetic fuels show great potential as they can be integrated into existing processes, with synthetic fuels from CO2 and renewable energies being considered the next big step towards a sustainable and ecological future. In our study, we focus on the sustainable production of ethanol and isobutanol, two common biofuels, using methanol and xylose derived from CO2 and lignocellulosic waste streams. Through enzyme and reaction optimization, we successfully produced ethanol or isobutanol from xylose and methanol. Our research opens up the possibility of hybrid production of biofuels and chemicals from CO2 and lignocellulosic waste streams, providing an alternative to conventional routes that rely solely on CO2 or sugars.

Summary: In the vision of achieving a circular economy that is carbon neutral or even negative, cell-free bioconversion of sustainable and renewable resources has emerged as a promising strategy. In vitro systems have enormous potential, offering technological, ecological, and ethical advantages. Innovative concepts have been developed in cell-free enzymatic conversions to reduce waste production, preserve fossil resources, and recycle industrial pollutants. However, the major challenge in the future will be the transition from concept to industrial application, which requires considerations of productivity, scalability, and cost-effectiveness. In this review, we briefly summarize the latest proof-of-concept cascades focusing on efficient recycling of greenhouse gases using carbon dioxide and other C1 or lignocellulose-derived chemicals, as well as cutting-edge technologies for advancing these concepts to industrial pilot plants.

Summary: The integration of redox enzymes on electrode surfaces enables the use of renewable energy for highly specific bioelectrochemical synthesis. In this study, the oxidation of glucose to gluconic acid was investigated on a bioanode, combining electrochemical and enzymatic components. The optimized redox film showed a faradaic efficiency of up to 96% for gluconate, and an oxygen-free setup exhibited quantitative electrosynthesis with a gluconate concentration of 6.4±0.25 mmol L-1. Furthermore, the catalase-free anaerobic system showed no production of H2O2 within 24 h, resulting in a highly stable and efficient enzyme performance.

Summary: The electrochemical production of hydrogen peroxide (H2O2) via 2-electron water oxidation reaction (WOR) has attracted considerable attention. Carbon materials, particularly boron-doped diamond (BDD) electrodes, exhibit high activity for anodic H2O2 generation. However, the high cost of BDD has limited its widespread use. This study explores the use of bipolar plates (BPP) as a low-cost alternative for stable anodic H2O2 generation.

Summary: In this study, the researchers successfully produced 1,2,4-butanetriol (BTO) from renewable resources, which has versatile applications in pharmaceuticals and plasticizers. By selecting appropriate enzymes and optimizing reaction conditions, they achieved a high titer of 1.2 M (125 g/L) (S)-BTO from D-xylose. Through the addition of an intermediate, they reduced the use of redox cofactors while maintaining a high space-time yield (STY). They also proposed strategies to further increase the titer and yield of BTO.

Summary: Currently, amino acid production is mainly used for livestock feed and food additives. The production relies on sugar fermentation, and it is estimated that the amino acid market will reach ten million tons with a market value over $13 billion USD by 2022. To make amino acid production more sustainable and environmentally friendly, alternative resources and waste streams need to be considered. This study presents a synthetic methanol alanine pathway (MAP) that produces L-alanine from methanol with a maximum theoretical yield of 90% through a cell-free enzymatic cascade. With the increasing possibility of sustainably producing methanol from CO2, this research paves the way for amino acid synthesis based on C1 building blocks and reduces environmental burden.
