Keeping condensates in liquid-like states throughout the biosynthesis process in microbial cell factories remains an ongoing challenge. Here, we present a light-controlled phase regulator, which maintains the liquid-like features of synthetic condensates on demand throughout the biosynthesis process upon light induction, as demonstrated by various live cell-imaging techniques. Specifically, the tobacco etch virus (TEV) protease controlled by light cleaves intrinsically disordered proteins (IDPs) to alter their valency and concentration for controlled phase transition and programmable fluidity of cellular condensates.

L-asparaginase (L-ASNase) can hydrolyze L-asparagine, a precursor to acrylamide, thereby reducing toxic acrylamide formation in fried foods. Currently, commercial L-ASNases are primarily produced by wild-type (WT) filamentous fungi; however, these enzymes often exhibit rapid activity loss during high-temperature processing due to limited thermal stability. In this study, we screened a thermostable L-ASNase gene from thermophile bacteria and expressed it in Aspergillus niger to reduce acrylamide content in French fries.
