Microflora and invert sugars in juice from healthy tissue of stored sugarbeets.
Bacterial populations increased in juice of healthy tissue of sugarbeet roots stored at 5 C. Average counts showed a sixfold increase after 150 days of storage. Invert sugar levels increased over threefold in "American 4 Hybrid A" and remained fairly constant in "Mono-Hy D-2." The former cultivar also had significantly higher bacterial colony counts than the latter before 90 days of storage. Of 36 isolates identified, 16 were Pseudomonas spp. including P. chlororaphis; 6 Bacillus spp. including B. subtilis; 5 Arthrobacter spp. including A. globiformis; 4 yeasts; 2 Erwinia spp; 2 Flavobacterium spp. including F. aquatile; and Streptomyces longisporus. Isolates of all genera except S. longisporus were able to hydrolyze sucrose in vitro.
