Aims:
The study deals with a number of heterofermentative Lactobacillus strains isolated from pig faeces and their identification.
Methods And Results:
SDS-PAGE of total soluble cell proteins and RAPD-PCR profiles were used to identify the strains isolated from pig faeces. Protein profiles obtained with SDS-PAGE revealed that 15 strains clustered at r >or= 0.78 with Lactobacillus buchneri and nine strains at r >or= 0.77 with two reference strains of Lactobacillus reuteri. The identity of the strains was confirmed with RAPD-PCR.
Conclusions:
Numerical analysis of protein profiles and RAPD-PCR proved valuable in the differentiation of Lactobacillus spp. isolated from pig faeces.
Significance:
This is the first report on the association of Lact. buchneri with pig faeces.
