The classical propionibacteria are aerotolerant or microaerophilic, although some strains may prefer aerobic conditions. Rodlike cells (Fig. 1.1) of these bacteria tend to be pleiomorphic. Rudimental branching is observed in dairy propionibacteria under aerobic conditions or anaerobically at low pH values. Colonies are usually wet, round or granular, bright and oily, although we (Vorobjeva et al., 1990) described strains forming dry leathery colonies, difficult to pick from the surface of solid medium. In liquid medium these strains (apparently P. shermanii) form heavy viscous sediment. Colonies can be creamy, orange, red, or brown. [Pg.9]

Recently, it has been shown (Roland et al., 1998) that dairy propionibacteria, especially P. acidipropionici (Pal and Pa3) and P. freudenreichii (Pfl through Pf7), can produce and liberate NO by reducing nitrate or nitrite. Nitric oxide is accumulated in the culture tubes without being further reduced by the bacteria. The authors have selected NO-producing strains (Propiovitum ) particularly resistant in vitro to the digestive stresses (acidity and bile). In humans, nitric oxide is produced from arginine and has fundamental roles in many vital functions, such as neurotransmission, vasodilation and intestinal motility. [Pg.222]

Numerous bacteriocins are produced by lactic acid bacteria (Klaenhammer, 1988), but only a few bacteriocins have been found in propionibacteria (Lyon and Glatz, 1991, 1993 Giinstead and Barefoot, 1992). Recently, 14 dairy propionibacteria were screened for catalase-insentitive, protease-sensitive inhibition of Gram-positive and Gramnegative bacteria (Ratnam et al., 1998). Bacteriocin production was identified in 57% of these cultures. [Pg.235]

Some dairy propionibacteria also may find application in medicine, besides being a source of vitamin B12 for industry (see Section 7.2.1). P. shermanii is a useful model for studying die regulation of ribonucleotide reductase (RNR) activity, which has a direct role in die control of cell division. On the basis of RNR inhibitors tested in P. shermanii antitumor preparations were developed (Elford et al., 1979a, b). [Pg.243]

The taxonomy of propionibacteria was given special consideration at the 1st International Symposium Dairy propionibacteria held in Rennes, France, in May 1995. [Pg.245]
