No pullulanase activity could be detected in maltose-grown cultures of 11 different strains of Escherichia coli. Neither these strains, nor 40 other strains of the same species would grow on pullulan, while all of them grew on maltose and some were shown to grow on maltotriose the exclusive product of pullulanase action on pullulan. These results are in contradiction with those reported last year in this journal by Palmer, Wöber and Whelan. On the other hand pullulanase activity could be detected, as reported by Bender and Wallenfels in 1966, in two strains of Aerobacter aerogenes. [ABSTRACT FROM AUTHOR]
