A–C. Strain with disruption of cphy3367 (AT02-1) had similar growth rates as wild type on glucose (A), cellobiose (B) and hemicellulose xylan (C). Growth curves are means of triplicate cultures. Error bars show one standard deviation and are smaller than the symbols where not apparent. D. Disruption of cphy3367 results in inability to degrade filter paper cellulose. Cellulose degradation was measured as dry mass of cellulose remaining in culture. E. After 4 weeks, cellulose strips in wild-type (wt) tubes had broken down while strips in AT02-1 cultures appeared unchanged.
