by Jim Lane (Biofuels Digest) Compared to prior generations, CodeXyme 4 and CodeXyme 4X significantly reduce the cost of cellulosic sugar production for biofuels and bio‐based chemicals.

…Codexis’ latest generation of advanced cellulase enzymes, CodeXyme 4 for dilute acid pretreatments and CodeXyme 4X for hydrothermal pretreatments, exhibits excellent performance, converting up to 85% of available fermentable sugars at high biomass and low enzyme loads. Combined with high strain productivity using the CodeXporter® enzyme production system, this allows for a cost‐in‐use that the company believes will be among the lowest available once in full‐scale commercial production.

…During the past several months, CodeXyme cellulase has been tested on a variety of feedstocks and pre‐treatments, including corn stover, corn cobs, sugarcane bagasse, cane straw, wheat straw and rice straw. In all cases, CodeXyme 4 and 4X have been found to convert 75 – 85% of glucan and xylan into C6 and C5 sugars, at 10 – 15g enzyme per kg of glucan. With consistently high sugar conversion, customers are able to convert more sugar into high‐value biofuels and bio‐based chemicals. READ MORE and MORE (Ethanol Producer Magazine)
