Upcycling imperfect broccoli and carrots into healthy snacks using an innovative 3D food printing approach.

Vegetables are healthy foods with nutritional benefits; however, nearly one-third of the world's vegetables are lost each year, and some of the losses happen due to the imperfect shape of the vegetables. In this study, imperfect vegetables (i.e.

Recombinant DNA techniques for bioremediation and environmentally-friendly synthesis.

A number of new recombinant DNA techniques have been developed for genetically engineered microorganisms for biodegradation of environmental contaminants or for the synthesis of small molecules. These techniques include new expression vectors to carry the heterologous genes into the host organism, new mechanisms to control gene expression, containment mechanisms to control persistence of genetically-engineered microorganisms, application of site-directed and random mutagenesis to increase the substrate range or activity of biodegradative enzymes, and methods to track genetically-engineered microorganisms.
