W.YR 1965 T1 Extracellular Polysaccharide Synthesis by Members of the Genus Lactobacillus: Conditions for Formation and Accumulation JF Microbiology, VO 40 IS 3 SP 297 OP 308 DO https://doi.org/10.1099/00221287-40-3-297 PB Microbiology Society, SN 1465-2080, AB SUMMARY Members of the genus Lactobacillus were examined for their ability to synthesize extracellular polysaccharide from sucrose. Strains physiologically similar to L. pastorianus synthesized a glucan. Other strains liberated a complex polysaccharide which contained mannose and glucose. Variants of the glucan-producing strains occurred spontaneously and these lacked the capacity to synthesize glucan ; however, extracts of these bacilli contained glucansucrase and invertase. Manometric studies indicated that the latter enzyme functioned in the sucrose metabolism of these non-glucan producing variants., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-40-3-297
