Identification of main bacteria and fungi found during beet sugar extraction in Spanish factories [Full subscriber]

A total of 758 strains (659 bacteria and 99 fungi) isolated from samples taken at different steps during beet sugar extraction in four Spanish factories were identified. From the lactic acid bacteria (LAB) found (54% of bacteria), gum forming bacteria (Leuconostoc spp.) were clearly dominant (76.1% of LAB), coming from diverse sources (mainly beets, cossettes, water and diffusion juice). Other LAB found were Lactobacillus, Enterococcus, Pediococcus and Lactococcus. Among no lactic acid bacteria, 65 strains of Bacillus (9.8% of bacteria) were found, being isolated mainly from diffusion juice, water and masses. The main species were B. licheniformis, Geobacillus stearothermophilus and…
