“…Orla-Jensen (19) observed that the members of the species L. casei could be divided into two groups on the basis of rhamnose fermentation and the ability to grow at 45 C. Orland (18) demonstrated that the two groups possessed different surface antigens. More recently, L. casei was divided into three subspecies by Rogosa et al (24) after an extensive survey of the phenotypic characteristics of a large number of isolates.…”

Representatives of both Streptococcus faecalis and Lactobacillus casei produce isofunctional malic enzymes. All 10 strains of S. faecalis tested could be induced to synthesize malic enzyme and readily adapted to growth on malate. Although 17 of 21 L. casei strains could be induced to produce malic enzyme, only 9 of 14 strains tested grew at the expense of malate. A comparison of catalytic and regulatory properties suggested that the malic enzymes from S. faecalis and L. casei were very similar. Immunological analyses showed that the numerous similarities in function actually reflected partial protein homologies; however, two distinct forms of the malic enzyme were detected among different strains of L. casei by immunochemical and serological procedures. The division of L. casei into two subgroups based on the immunological type of malic enzyme synthesized corresponds to two subspecies currently recognized by microbial taxonomists.An inducible nicotinamide adenine dinucleotide (NAD)-specific malic enzyme from Streptococcus faecalis was shown to be a regulatory protein capable of interacting with three negative effectors which are intermediate products of glucose dissimilation, namely, fructose-1,6-diphosphate (FDP), 3-phosphoglycerate (3PGA), and 6phosphogluconate (6PG; reference 13). A survey of several strains of Lactobacillus casei revealed that at least one of these organisms could also be induced to synthesize an NAD-specific malic enzyme and subsequently grow at the expense of malate. The L. casei malic enzyme bore a striking resemblance to the streptococcal enzyme (London, Meyer, and Kulczyk, Biochim. Biophys. Acta, in press). In addition to similarities in catalytic properties, the Lactobacillus malic enzyme was also inhibited by FDP and 3PGA.A comparison of the physical, catalytic, and regulatory properties of a number of S. faecalis glucose was used to maintain and cultivate the strains of L. casei. Both species were grown as follows. One-126 on July 16, 2020 by guest

“…rharnnosus, a variety which can be distinguished from L, casei biochemically (Rogosa et aE. 1953) and also serologically by the possession of a particular type antigen (Orland, 1950;Sharpe, 1955a). Within subgroup 2, C6, P l , and P11 were all of the same serological type and could not be differentiated separately on the basis of their spectral features.…”

SUMMARY:The infra-red absorption spectra of 76 strains of lactobacilli representing 11 different species were examined. With only a few exceptions, the spectra could be grouped into 5 distinct spectral types, each corresponding to a Lactobacillus species or a group of related species. Fkom a study of acetic acid extracts, it has been found possible to relate spectral differences to the relative concentrations of nucleic acids and carboxylate groups in the different organisms.

“…Previously Orla-Jensen (1919) observed 2 varieties, one of which fermented rhamnose and grew at 45 C, and suggested that they might well be regarded as separate species. Orland (1950) has shown that these 2 varieties possess dissimilar antigenic components.…”

“…The group 2 strains are identical with strains designated as Lactobacillus arabinosus by Fred, Peterson, and Anderson (1921) and also studied by Tittsler, Geib, and Rogosa (1947). Orland (1950) has discovered a new major antigen (G) in L. arabinosus. In the judgment of the present authors L. arabinosus Fied et al is a distinct species.…”
