This study aimed to isolate lactic acid bacteria from monkey faeces and evaluate their safety and probiotic properties through a combination of in vitro assays and complete genomic sequencing. The results revealed that two Limosilactobacillus reuteri strains (LDHa and LSHe) exhibited promising probiotic attributes: no hemolytic activity, remarkable antibacterial activity against intestinal pathogens, high bile salt tolerance (77.46% survival rate for LDHa at 0.3% bile salt concentration), excellent gastrointestinal resistance (survival rate > 40%), and favorable surface characteristics (63.92-66.00% auto-aggregation; 91.33-93.80% hydrophobicity). The whole genome sequencing results revealed that strain LDHa has a total length of 2,031,794 bp with a GC content of 39.02% and contains (Strompfová et al. 2014) coding genes. The LSHe strain has a total length of 2,031,507 bp with a GC content of 39.02% and contains 1954 coding genes. Genomic analysis revealed that both strains possess four CRISPR sequences and one secondary metabolic gene cluster, with functional annotations from the EGGNOG, KEGG, and CAZy databases demonstrating genome stability; the absence of horizontally transferable antibiotic resistance genes; the enrichment of metabolic pathway-related genes, and probiotic-associated functional potential including antimicrobial, anti-inflammatory, immunomodulatory, and antitumor activities. This study demonstrated that L. reuteri LDHa and LSHe exhibit favorable safety profiles and probiotic potential at both physiological and genomic levels, positioning them as promising candidates for probiotic formulations in captive primate populations.202540852645

Of these CDSs, 99.13% (2,758 proteins) were assigned to functional categories in the Clusters of Orthologous Group (COGs) classification system, while 49 proteins remained uncharacterized. Our genome analysis identified no antibiotic resistance (ABR) or antimicrobial resistance (AMR) genes, indicating that L. rhamnosus B3421 is a safe probiotic bacterium with minimal risk of contributing to the horizontal transfer of antibiotic resistance within the gut microbiome. Additionally, the genome contains genes associated with the ggmotif (PF10439), Enterocin X chain beta, and Carnocin CP52, as identified through BAGEL4 analysis, along with 24 other genes related to reductase or peroxidase activities. These genes may confer competitive advantages against pathogenic bacteria and oxidative stress. Our findings highlight the probiotic potential of L. rhamnosus B3421 and its prospective applications in promoting human and animal health.202540877785
613660.9901Complete genome sequences of Lacticaseibacillus paracasei INIA P272 (CECT 8315) and Lacticaseibacillus rhamnosus INIA P344 (CECT 8316) isolated from breast-fed infants reveal probiotic determinants. Lacticaseibacillus paracasei INIA P272 and Lacticaseibacillus rhamnosus INIA P344, isolated from breast-fed infants, are two promising bacterial strains for their use in functional foods according to their demonstrated probiotic and technological characteristics. To better understand their probiotic characteristics and evaluate their safety, here we report the draft genome sequences of both strains as well as the analysis of their genetical content. The draft genomes of L. paracasei INIA P272 and L. rhamnosus INIA P344 comprise 3.01 and 3.26 Mb, a total of 2994 and 3166 genes and a GC content of 46.27 % and 46.56 %, respectively. Genomic safety was assessed following the EFSA guidelines: the identification of both strains was confirmed through Average Nucleotide Identity, and the absence of virulence, pathogenic and antibiotic resistance genes was demonstrated. The genome stability analysis revealed the presence of plasmids and phage regions in both genomes, however, CRISPR sequences and other mechanisms to fight against phage infections were encoded. The probiotic abilities of both strains were supported by the presence of genes for the synthesis of SCFA, genes involved in resistance to acid and bile salts or a thiamine production cluster. Moreover, the encoded exopolysaccharide biosynthesis genes could provide additional protection against the deleterious gastrointestinal conditions, besides which, playing a key role in adherence and coaggregation of pathogenic bacteria together with the high number of adhesion proteins and domains encoded by both genomes. Additionally, the bacteriocin cluster genes found in both strains, could provide an advantageous ability to compete against pathogenic bacteria. This genomic study supports the probiotic characteristics described previously for these two strains and satisfies the safety requirements to be used in food products.202235868412

6138110.9898Draft genome of five Cupriavidus plantarum strains: agave, maize and sorghum plant-associated bacteria with resistance to metals. Five strains of Cupriavidus plantarum, a metal-resistant, plant-associated bacterium, were selected for genome sequencing through the Genomic Encyclopedia of Bacteria and Archaea (GEBA) Phase IV project at the Joint Genome Institute (JGI) of the U.S. Department of Energy (DOE). The genome of the strains was in the size range of 6.2-6.4 Mbp and encoded 5605-5834 proteins; 16.9-23.7% of these genes could not be assigned to a COG-associated functional category. The G + C content was 65.83-65.99%, and the genomes encoded 59-67 stable RNAs. The strains were resistant in vitro to arsenite, arsenate, cobalt, chromium, copper, nickel and zinc, and their genomes possessed the resistance genes for these metals. The genomes also encoded the biosynthesis of potential antimicrobial compounds, such as terpenes, phosphonates, bacteriocins, betalactones, nonribosomal peptides, phenazine and siderophores, as well as the biosynthesis of cellulose and enzymes such as chitinase and trehalase. The average nucleotide identity (ANI) and DNA-DNA in silico hybridization of the genomes confirmed that C. plantarum is a single species. Moreover, the strains cluster within a single group upon multilocus sequence analyses with eight genes and a phylogenomic analyses. Noteworthy, the ability of the species to tolerate high concentrations of different metals might prove useful for bioremediation of naturally contaminated environments.202032405446
5184120.9898In silico evaluation of genomic characteristics of Streptococcus infantarius subsp. infantarius for application in fermentations. This study aims to evaluate the in silico genomic characteristics of Streptococcus infantarius subsp. infantarius, isolated from Coalho cheese from Paraíba, Brazil, with a view to application in lactic fermentations. rRNA sequences from the 16S ribosomal region were used as input to GenBank, in the search for patterns that could reveal a non-pathogenic behavior of S. infantarius subsp. infantarius, comparing mobile genetic elements, antibiotic resistance genes, pan-genome analysis and multi-genome alignment among related species. S. infantarius subsp. infantarius CJ18 was the only complete genome reported by BLAST/NCBI with high similarity and after comparative genetics with complete genomes of Streptococcus agalactiae (SAG153, NJ1606) and Streptococcus thermophilus (ST106, CS18, IDCC2201, APC151) revealed that CJ18 showed a low number of transposases and integrases, infection by phage bacteria of the Streptococcus genus, absence of antibiotic resistance genes and presence of bacteriocin, folate and riboflavin producing genes. The genome alignment revealed that the collinear blocks of S. thermophilus ST106 and S. agalactiae SAG153 have inverted blocks when compared to the CJ18 genome due to gene positioning, insertions and deletions. Therefore, the strains of S. infantarius subsp. infantarius isolated from Coalho cheese from Paraíba showed genomic similarity with CJ18 and the mobility of genes analyzed in silico showed absence of pathogenicity throughout the genome of CJ18, indicating the potential of these strains for the dairy industry.202236417612
