Marrone starts production at Michigan plant
The US biopesticide company, Marrone Bio Innovations (Davis, California), has begun producing the first batch of its bioinsecticide, Grandevo (Chromobacterium subtsugae strain PRAA4-1T), at its manufacturing facility in Bangor, Michigan. The company acquired the former biodiesel and glycerine production plant in August 2012 and started converting it into a fermentation facility (Agrow No 646, p 2). Installation of the first three fermentation tanks marks the first phase of a conversion and expansion programme that will cost around $32 million. Future phases will include production of the biofungicide, Regalia (Reynoutria sachalinensis extract), and installing larger fermenters that will allow the manufacture of multiple products at higher volumes, the company points out.
