Lactobacillus reuteri inhibits Staphylococcus aureus growth on Baird-Parker agar. This activity required the presence of tellurite and was not shared with other lactic acid bacteria or an L. reuteri mutant defective in cystine metabolism. Secreted products generated from L. reuteri cystine metabolism and thiols were shown to augment tellurite toxicity.

reuteri) is a well-studied probiotic bacterium that can colonize a large number of mammals. In humans, L. reuteri is found in different body sites, including the gastrointestinal tract, urinary tract, skin and breast milk. The abundance of L. reuteri varies among different individuals. Several beneficial effects of L. reuteri have been noted.
and colony growth, the use of a large number of well characterised strains is necessary. Growth must be com pared on a significant number of different media in well defined conditions. For our investigation we used thirty Lactobacillus-slrams and four strains belonging to other genera, but known as common brewery infectants. Eleven Acrobat 4.0 Import Plug-in for Windows Genetic optimization was continued till the maximum cell mass yield obtained.
[58] The mechanism by which L. reuteri is able to support healthy growth is not entirely understood.
Lactobacillus reuteri has been shown to survive the passage through the ventricle and to colonize the human gastrointestinal tract transiently [9]. Under certain favourable conditions, L. reuteri produces a broad-spectrum antimicrobial substance, reuterin, assumed to inhibit DNA synthesis in pathogens in the surrounding environment [10]. In a

I know lactobacilli are facultative anaerobes that grow best in anaerobic/microaerobic conditions. However, I do not have access to any anaerobic equipment in my lab.
In this study, we first developed an efficient immobilization process involving magnetic cell entrapment for production of reuterin from glycerol by Lactobacillus reuteri. The cell growth condition was optimized by statistical approaches. Lactobacillus reuteri has been shown to survive the passage through the ventricle and to colonize the human gastrointestinal tract transiently [9].
Strains are isolated from dairy and meat products and from animal sources. Lactobacillus reuteri is a probiotic culture and a member of the NSLAB population in several cheese varieties (e.g., Cheddar, Grana Padano, Gruyère, Idiazabal, Parmigiano Reggiano, Roncal, and Toma). The optimal conditions for the growth were (Temp. 30oC, pH 6.5) with an optical density around (1.9297) at 540 nm, while the lowest growth rate was at (Temp. 25oC, pH 3.5) with an optical density around (0.0002) at 540 nm.

III Wall, T., Båth, K., Britton, RA., Jonsson, H., Versalovic, J. & Roos, S. The early response to acid shock in Lactobacillus reuteri involves the ClpA chaperone and cell surface alteration. Lactobacillus reuteri resides in the gastrointestinal tract of humans, swine, poultry and other animals. Resting cells of this species convert glycerol into a potent, broad-spectrum antimicrobial substance termed reuterin. Reuterin is a low molecular weight, neutral, water soluble compound, capable of inhibiting growth of species representing all Lactobacillus reuteri inhibits Staphylococcus aureus growth on Baird-Parker agar.
In addition, L. reuteri could reduce intestinal inflammation via inhibiting TLR4-nuclear factor κB (NF-κB) signaling pathway (Liu et al., 2012).

Lactobacillus reuteri strains used in the study were obtained from the Collection of Micro‐organisms of Institute of Microbiology and Biotechnology University of Latvia. Media and growth conditions. MRS growth medium (De Man et al. 1960) was used for the maintenance and propagation of the cultures.
