Homo- and heterofermentative species of Lactobacillus have been isolated from sugary kefir grains. Most of the homofermentative strains fermented tagatose and aldonitol and presented 48-54% of homology with Lactobacillus paracasei ssp. paracasei NCDO 151 (ex Lactobacillus casei). The two variants of a hetero-fermentative species, although fermenting arabinose, were related to Lactobacillus hilgardii NCDO 264 (type strain) with 88% of homology. One of them produced polysaccharide from sucrose at pH 4.8 and 30 degrees C; the best glucose conversion into polysaccharide was obtained from 3% of sucrose (81.8%), and the maximum production occurred about 35 hours after the end of the log phase of growth, in MRS sucrose broth. Polysaccharide formation did not occur above 40 degrees C, a temperature at which no growth was observed. The two variants were forming minicells by abnormal divisions.
