According to an article in Applied & Environmental Microbiology 59(2):
607-609 (1993); "Development and Use of a Selective Medium for Isolates of
Leuconostoc spp. from Vegetables and Dairy Products" lactobacilli is
resistant to vancomycin.
What is lactobacilli's sensitivity to vancomycin ?
I have used MRS agar with 100 microgram vancomycin/ml to for differential
count of leuconostoc and pediococci. The pH of the agar was 6,2+/-0,2. Is it
possible that heterofermentative lactobacilli can grow on this agar type ?
