Biotech route for rubber: Natural rubber trumps synthetic, petroleum-derived rubber in useful qualities such as elasticity and abrasion resistance. But rubber trees are quite susceptible to disease, leading scientists to search for other sources of natural rubber and to understand the specifics of its biosynthesis. Lettuce plants are a source of natural rubber, and now Qu et al. identify a scaffold protein called CPTL2 that keeps rubber-synthesizing enzymes from bouncing around the cell. Tethered to the cell’s endoplasmic reticulum, CPTL2 anchors a protein important for rubber polymerization in place. Plants with reduced expression of CPTL2 could not synthesize rubber, revealing its essential role.  From the Journal of Biological Chemistry, 2014

Three research articles published recently relevant to Industrial Microbiology.   Simultaneous consumption of Cellobiose, Xylose and Acetate. Uniqueness in the cellobiose paper published in ACS synthetic biology: co-consumption of cellobiose, xylose and acetate; evolutionary engineering for increased cellobiose consumption; sequencing revealed increased copy numbers of a particular gene than mutations; co-fermentation had higher ethanol yields and lower by-product formation. Producing a natural product using a consortium … Continue reading Research News – 5
