Patent number: 8586339Abstract: A two-stage heat treatment process is provided to improve the processability of recombinant microbial biomass comprising an enzyme having perhydrolytic activity. More specifically, a process is provided to treat the recombinant microbial biomass comprising a Thermotoga sp. acetyl xylan esterase having perhydrolytic activity such that microfiltration may be used to partially-purify and/or concentrate protein preparations. The acetyl xylan esterase may be used to produce peroxycarboxylic acids suitable for use in a variety of applications such as cleaning, disinfecting, sanitizing, bleaching, wood pulp processing, and paper pulp processing applications.Type: GrantFiled: March 23, 2011Date of Patent: November 19, 2013Assignee: E.

Patent number: 8003356Abstract: Methods for the microbial production of para-hydroxycinnamic acid (pHCA) and cinnamic acid (CA) are provided. Microbes producing either tyrosine or phenylalanine are grown in the presence of either tyrosine ammonium lyase or phenylalanine ammonium lyase respectively where some part of the fermentation is accomplished at alkaline pH. The process results in greater yields and higher rates of para-hydroxycinnamic acid (pHCA) and cinnamic acid (CA) production as compared with fermentation exclusively at physiological pH.Type: GrantFiled: April 13, 2005Date of Patent: August 23, 2011Assignee: E.
