Creating a multifunctional degrader for co-mineralization of p-nitrophenol and 1,2-dichloroethane and its application in wastewater bioremediation.

Because the interactions among contaminants may lead to enhanced toxicity, combined pollution caused by the co-presence of multiple contaminants has increasingly gained public concern. p-Nitrophenol (PNP) and 1,2-dichloroethane (1,2-DCA) are frequently co-detected in groundwater. To completely eliminate PNP, 1,2-DCA and intermediates from polluted sites, in this study, a novel degrader KTU-PDG was created by functional assembly of PNP and 1,2-DCA biodegradation pathways in a robust chassis Pseudomonas putida KT2440.

Promoting Photosynthetic Production of Dammarenediol-II in via Gene Loading and Culture Optimization.

Ginsenosides are major bioactive compounds found in that exhibit various pharmaceutical properties. Dammarenediol-II, the nucleus of dammarane-type ginsenosides, is a promising candidate for pharmacologically active triterpenes. Dammarenediol-II synthase (DDS) cyclizes 2,3-oxidosqualene to produce dammarenediol-II.
