摘要

The insertional inactivation of the dlt operon from Lactobacillus plantarum NCIMB8826 had a strong impact on lipoteichoic acid (LTA) composition, resulting in a major reduction in d-alanyl ester content. Unexpectedly, mutant LTA showed high levels of glucosylation and were threefold longer than wild-type LTA. The dlt mutation resulted in a reduced growth rate and increased cell lysis during the exponential and stationary growth phases. Microscopy analysis revealed increased cell length, damaged dividing cells, and perforations of the envelope in the septal region. The observed defects in the separation process, cell envelope perforation, and autolysis of the dlt mutant could be partially attributed to the L. plantarum Acm2 peptidoglycan hydrolase.
