The genome sequences of 43 Lactobacillus strains from the species L. curvatus, L. fermentum, L. paracasei, L. plantarum, L. rhamnosus, and L. sakei were determined using Illumina MiSeq.
We describe the first case of continuous ambulatory peritoneal dialysis (CAPD)-related peritonitis due to Lactobacillus paracasei. It occurred in a 65-year-old patient with recurrent episodes of peritonitis while he was receiving a prolonged course of intraperitoneal vancomycin. L. paracasei should be considered in the differential diagnosis of pathogens in CAPD-related peritonitis, especially ...
Lactobacillus paracasei N1115 is a new strain with probiotic properties isolated from traditional homemade dairy products in Inner Mongolia, China. Here, we report the complete genome sequence of L. paracasei N1115, which shows high similarity to the well-studied probiotic Lactobacillus rhamnosus GG, and 3 structures turned out to be inversions, according to the colinearity analysis of the BLAS...
BACKGROUND Quenching in cold buffered methanol at -40 °C has long been the preferred method for sub-second inactivation of cell metabolism during metabolic fingerprinting. However, methanol is known to cause intracellular metabolite leakage of microbial cells, making the distinction between intra- and extracellular metabolites in microbial systems challenging. In this paper, we tested three que...
Hydrophilic and electrostatic cell surface properties of eight Lactobacillus strains were characterized by using the microbial adhesion to solvents method and microelectrophoresis, respectively. All strains appeared relatively hydrophilic. The strong microbial adhesion to chloroform, an acidic solvent, in comparison with microbial adhesion to hexadecane, an apolar n-alkane, demonstrated the par...
Benzoic acid is occasionally used as a raw material supplement in food products and is sometimes generated during the fermentation process. In this study, the production of naturally occurring yogurt preservatives was investigated for various starter cultures and incubation temperatures, and considered food regulations. Streptococcus thermophilus, Lactobacillus acidophilus, Lactobacillus delbru...
We determined the maximum pH that allows growth (pHmax) for 34 strains of lactobacilli. High alkali tolerance was exhibited by strains of Lactobacillus casei, L. paracasei subsp. tolerans, L. paracasei subsp. paracasei, L. curvatus, L. pentosus, and L. plantarum that originated from plant material, with pHmax values between 8.5 and 8.9. Among these, L. casei NRIC 1917 and L. paracasei subsp. to...
Competition of commensal and probiotic bacteria with pathogens for adhesion and colonization is one of the important protective mechanisms of gastrointestinal tract. In this study, we examined the ability of Lactobacillus paracasei to inhibit the adhesion of pathogenic Salmonella enterica to human colon adenocarcinoma Caco-2 cells. Caco-2 cells were grown for 6 or 21 days to obtain nondifferent...
The concentrations of gamma-aminobutyric acid (GABA) in 22 Italian cheese varieties that differ in several technological traits markedly varied from 0.26 to 391 mg kg(-1). Presumptive lactic acid bacteria were isolated from each cheese variety (total of 440 isolates) and screened for the capacity to synthesize GABA. Only 61 isolates showed this activity and were identified by partial sequencing...
A series of expression cassettes which mediate secretion or surface display of antibody fragments was stably integrated in the chromosome of Lactobacillus paracasei. L. paracasei producing surface-anchored variable domain of llama heavy chain (VHH) (ARP1) directed against rotavirus showed efficient binding to rotavirus and protection in the mouse model of rotavirus infection.
