Bacterial contaminants of micropropagated plant cultures

Abstract

Bacterial contaminants of micropropagated plant cultures were isolated and characterized with standard bacteriological tests and appropriate API strips. Results obtained were analysed by the API identification software. Of 198 bacterial strains isolated from nine plant species, 90% were identified as Bacillus, Enterobacter, Micrococcus, Staphylococcus, Pseudomonas or Lactobacillus species. Possible sources of contamination are discussed.
