		While spore bearing lactobacilli are facultative anaerobes, the rest are strictly anaerobic.
		The ability of lactobacilli to convert lactose to lactic acid is used in the successful treatment of lactose intolerance.
		The inhibitory activity of lactobacilli towards putrefactive organisms is thought to be partially due to the production of bacteriocins.

		The assessment of the lactobacilli, proportional to the total in vivo microbial population of the intestinal tract of humans, is difficult, and modern concepts of colonization and population ratios are largely based on data obtained from monogastric animals.
		Lactobacilli are indigenous to the stomach of rodents and pigs and to the crop of chickens, thickly colonizing the surface of stratified squamous epithelium in the oesophagus, crop, or stomach of these neonatal and young animals (Savage, 1977; Tannock et al., 1982, 1987).
		Lactobacilli are the dominant group in the grains and in addition leuconostocs and lactococci were also identified (Kunath, 1983).

	Lactobacilli - Oral Health
		Lactobacilli that are most frequently associated with active caries lesions in dentine were isolated and identified as part of a research project which aims to determine the role of the predominant species of these organisms in the carious process.
		Furthermore, the occurrence of mutans streptococci and lactobacilli was determined in samples taken from the tongue of the children, and the buffer capacity of the saliva was measured.
		The roles of lactobacilli and S. aureus in the induction of dental caries under the hyposalivated condition were discussed and it was suggested that lactobacilli may play some significant role in the induction of dental caries in hyposalivated rats.

	In situ delivery of passive immunity by lactobacilli producing single-chain antibodies - Nature Biotechnology
		Lactobacilli were eluted from a cotton swab from the oral cavity and nontransformed bacteria colonized more effectively (approximately 10,000 colonies per swab) than transformants (approximately 1,000 colonies per swab).
		The long persistence of the transformed lactobacilli in the oral cavity and their therapeutic efficacy suggests that this may be a viable approach for future therapy either prophylactically or therapeutically.
		Lactobacilli expressing monovalent scFv on their surfaces, however, would be anticipated to work effectively as "biological beads" because of the multivalent binding, resulting in high avidity.

		On the bad side, lactobacilli are responsible for acrolein and lactic acid, leading to typical ‘off-notes’ when present in large enough concentrations.
		Lactobacilli on the other hand are much more a part of the local micro-climate, so could they play a role in the taste variation among whiskies from different distilleries?
		The result of this cluster analysis is that distilleries that are similar in their community of lactobacilli are grouped together in the resulting ‘tree’, whereas distilleries that differ very much come out widely separated.

	Bacteria
		Lactobacilli are one of the most important types of friendly bacteria found in the digestive tract.
		The "father" of lactobacilli could well be Elie Metchnikoff, who, in 1908, noted that people in Bulgaria lived longer than those in other countries, despite the fact that Bulgaria was considered "underdeveloped." His investigation of this led him to diet, yogurt, and lactobacilli.
		Lactobacilli are able to "balance" unfriendly bacteria because when they produce lactic acid, they alter the intestinal environment, making it unsuitable for unfriendly bacteria.

	Lactobacilli in the Gastrointestinal Tract
		Lactobacilli in the Gastrointestinal Tract: The majority of studies on intestinal lactobacilli, especially in the last two decades, have been focused on the behaviour of lactobacilli introduced into the gastrointestinal tract as probiotics and their in vitro characterization.
		Research on the ecology of lactobacilli naturally present within the complex gastrointestinal microbiota of humans and animals has received much less attention but is a crucial aspect of probiotic research and development.
		Animal models in combination with biochemical and genetic approaches have been used to reveal the influence of lactobacilli on the host, on microbiota-associated characteristics and on other members of the gut microbiota as well as to identify some bacterial factors that contribute to the ecological performance of lactobacilli in the gut.

		Despite the existence of several varieties of yeast and lactobacilli they showed that the dominant yeast was a non spore forming variety of Saccharomyces exigus called Torulopsis holmii and now reclassified as Candida milleri sp.
		Thus maltose is freely available to the lactobacilli which have an absolute requirement for this sugar and they cannot utilise other sugars present in dough.
		The lactobacilli also secrete an antibiotic cycloheximide which "sterilises" the dough since it kills many organisms but of course Candida milleri is resistant to cycloheximide.

		Some strains of L. acidophilus have been shown to increase the total fecal lactobacilli content when administered orally in fermented milks, but administration of some other strains in gelatine capsules did not result in colonization of small intestine or any increase in total fecal Lactobacillus counts.
		The colonization of human intestinal mucosa with lactic-acid bacteria was demonstrated in vivo by a Swedish group.[2] In this work, a cocktail of 19 Lactobacillus strains was administered in oatmeal soup to healthy volunteers, and biopsy samples were taken from the upper jejunal and rectal mucosa before the administration and 1 and 11 days thereafter.
		An increase in the lactobacilli counts on the jejunal and rectal mucosa was noticed, but the increase was significant only in the jejunum.

		Lactobacilli and Bifidobacteria also show anti-cancer activity, by two mechanisms: they inhibit the growth or activity of cancer-promoting bacteria and some strains actually produce chemicals which inhibit tumor growth.
		The most reliable way to supplement your diet with Lactobacilli is to make your own yogurt or sauerkraut, or to buy nutritional supplements which have been tested by an independent outside laboratory and which list the concentration of viable bacteria found on culture.
		Lactobacilli not only colonize the intestinal tract but grow well in the vagina and the urethra, where they prevent growth of pathogenic bacteria.
