Eight mutants of Bacillus subtilis deficient in xylan utilization were isolated and
characterized genetically and biochemically. Each mutant was obtained independently
after nitrosoguanidine mutagenesis. All of the analyzed mutations were
shown to be linked. Reciprocal transformation crosses revealed the existence of
two genes controlling xylan utilization which have been designated xynA and
xynB. Available data have indicated that these two genes code for two xylandegrading
enzymes existing in the wild-type strains, an extracellular P-xylanase
(xynA) and a cell-associated 1-xylosidase (xynB).
