Optogenetic regulation of artificial microRNA improves H2 production in green alga Chlamydomonas reinhardtii.
Abstract:
Chlamydomonas reinhardtii is an ideal model organism not only for the study of basic metabolic processes in both plants and animals but also the production of biofuels including hydrogen. Transgenic analysis of C. reinhardtii is now well established and very convenient, but inducible exogenous gene expression systems remain under-studied. The most commonly used heat shock-inducible system has serious effects on algal cell growth and is difficult and costly to control in large-scale culture. Previous studies of hydrogen photoproduction in Chlamydomonas also use this heat-inducible system to activate target gene transcription and hydrogen synthesis.
