The growth of facultatively heterofermentative lactobacilli (FHL)
on cell suspensions of the homofermentative Lactobacillus helveticus was investigated. Osmotic lysis of L. helveticus led to a significant increase of ribose. It decreased
steadily in parallel with the growth of FHL, strongly suggesting that
the bacteria used ribose as a growth substrate.
