Being a greenhouse gas, methane is a threat to biodiversity. Hence, the utilization of methane by converting it into a valuable chemical like methanol is one of the most promising reactions. To solve that problem, a large number of studies have been performed on methane-to-methanol conversion (MTM process). Still, to date, the production of methanol from methane on an industry scale is a crucial challenge. After a th Read More

Biocatalysis is an approach to green chemistry. A crucial step in the synthesis of organic compounds is the reduction of aldehydes and ketones to secondary alcohols. The use of a biocatalyst, such as enzymes or entire cells, has not affected this process. It offers great selectivity, high specificity, and an environmentally friendly approach to synthesis. Dried baker's yeast mediates the conversion of optically active alcoho Read More
