MICROBIOLOGY Correction for “Demonstration of the importance for cellulose hydrolysis of CelS, the most abundant cellulosomal cellulase in Chlostridium thermocellum,” by David B. Wilson, which appeared in issue 42, October 19, 2010, of Proc Natl Acad Sci USA (107:17855–17856; first published October 4, 2010; 10.1073/pnas.1012746107).
The author notes that the title of his manuscript appeared incorrectly. The title should appear as “Demonstration of the importance for cellulose hydrolysis of CelS, the most abundant cellulosomal cellulase in Clostridium thermocellum.” Additionally on page 17855, middle column, first paragraph, line four, Chlostridium should instead read Clostridium. The online version has been corrected. This error does not affect the conclusions of the article.
