“…It is defined as the production of biofuels and biomaterials from biomass based on biotechnology (Yang et al 2015;Ibrahim et al 2018). In particular, a biorefinery, which uses carbon-neutral biomass as raw material and converts it into useful materials, is attracting great attention as an alternative to the existing petroleum-based refining because it is a core technology of a sustainable green industry (Kim et al 2018(Kim et al , 2020.…”

“…Based on the development of genetic engineering, it is possible to bioconvert target bio-products using various organic wastes as feedstock (Kim et al 2020). The utilization of organic wastes such as agricultural residues, crude glycerol, fruits peel, juice processing residues, municipal wastes, spent coffee grounds, waste cooking oils, and waste paper sludge has been reported, and its origins are very diverse: urban, agricultural, food processing, paper industry, and biodiesel production processes (Ibrahim et al 2018;Estrada-Martínez et al 2019;Lee et al 2020a,b).…”

Biorefining, which uses biomass as feedstock and converts it into valuable products, is a core technology for the sustainable green industry and has high potential as an alternative to the current petrochemical-based industry. This article covers the requirements for feedstock that should be met for the economic feasibility of a biorefinery. In particular, organic waste that meets several requirements as the next-generation biomass has high potential. However, the complex and significant differences in composition depending on the origin make it difficult to follow the previous system of classification such as cellulose, hemicellulose, and lignin. In particular, several organic wastes contain high value-added bioactive components. Therefore, a strategy for the effective use of high value-added ingredients contained in trace amounts is required, which is briefly introduced in the third section of this article.

“…For the process of protein hydrolysis to amino acids, some amino acids produce 2-keto acids, which are precursors of isobutanol. Liao's group [65,86] has pioneered the use of proteins as feedstock for higher alcohols production. In E. coli, they used chemical mutagenesis to screen the YH19 strain that can utilize 13 amino acids as a sole carbon source.…”

Environmental issues have prompted the vigorous development of biorefineries that use agricultural waste and other biomass feedstock as raw materials. However, most current biorefinery products are cellulosic ethanol. There is an urgent need for biorefineries to expand into new bioproducts. Isobutanol is an important bulk chemical with properties that are close to gasoline, making it a very promising biofuel. The use of microorganisms to produce isobutanol has been extensively studied, but there is still a considerable gap to achieving the industrial production of isobutanol from biomass. This review summarizes current metabolic engineering strategies that have been applied to biomass isobutanol production and recent advances in the production of isobutanol from different biomass feedstocks.

“…In addition to ammonia recovery, utilizing the carbon skeleton of 2‐keto acids is of great interest. The protein biomass must be pretreated to utilize the 2‐keto acids derivatives directly 11, 12. Protein hydrolysis is required and process optimization studies must be performed 13–16.…”

Amino acids are a valuable bioresource that contains both the acid form of carbon and the amine group of nitrogen. Amino acids not only constitute proteins and the building blocks for living organisms but also provide a key intermediate for controlling the nitrogen balance in cells. The production of amino acids using microorganisms has, along with the development of biotechnology, created a large market for biochemicals. In parallel, there have been various biochemical production methods using pulmonary proteins or direct amino acids as biomass through enzymatic bioconversion or whole‐cell biotransformation. The deamination of amino acids facilitated the applications of 2‐keto and acrylic acids, in particular, for biofuels of bio alcohol, pharmaceuticals, cosmetics, as building blocks for polymers, and other versatile industrial chemicals. In this review, we report on the application of amino acids derived from biochemicals initiated by deamination reactions using deaminase, ammonia‐lyase, and oxidase enzymes for biotechnology applications.
