“…Biocatalysis is considered as a cornerstone of a sustainable bioeconomy. , However, it is not widely applied in the fine chemical industry, yet, because the success of biocatalysis is limited by the speed of development and implementation of bioprocesses . In order to accelerate development, novel concepts and integrated approaches to process design have been successfully explored, such as synthetic biology, retrobiosynthesis, , and biofoundries. , They all take advantage of decreasing sequencing costs, which reduced by 6 orders of magnitude in the last 20 years (), high throughput experimental techniques, such as liquid handling and microfluidics techniques for screening of enzyme libraries, − substrate libraries, or reaction conditions, − and automated robotic platforms for screening and design. − As a consequence, a rapidly increasing stream of data is generated, which feeds data-driven modeling methods that depend on large volumes of data. Machine learning is applied to guide directed evolution of enzymes and to efficiently explore reaction space .…”
