RESUMO
Lactic acid bacteria are known to exhibit probiotic properties through various mechanisms including production of antimicrobial substances and bile salts tolerance. Here, we report a draft genome sequence of Lacticaseibacillus rhamnosus ISO20, a lactic acid bacterium isolated from raw goat's milk to provide genomic insight into its strategies as probiotic strain.
RESUMO
Here, we present the genome assembly of E. coli strain HMVC1 isolated from rectal fecal samples of healthy cattle in South Africa. The genome size of HMVC1 consisted of 5,043,843 bp, with G + C content of 50.5%. The strain harbors marA, mdtM, acrF, acrD, and other antimicrobial resistance genes.
RESUMO
We present draft genome sequences of 12 Enterobacter hormaechei strains from feces isolated from cow rectums in the North West province, South Africa. The genome sizes ranged from 4.43 to 5.02Mb, with G + C contents of 55.5-56%, and contained 16-262 contigs. These data will contribute to our knowledge of the ecology and diversity of this species in South Africa.
RESUMO
Pediococcus acidilactici is a beneficial lactic acid bacterium frequently studied for its probiotic potential. Here, we present a 2.32-Mb draft genome sequence of strain ISO17, with a G+C content of 42%. The genome was predicted to harbor 4 rRNA genes, 47 tRNA genes, and 2,297 protein-coding sequences.
RESUMO
Lactiplantibacillus plantarum strain ISO1, a potential probiotic with wide food and biotechnological applications, was isolated from the raw milk of South African Saanen goats. Here, we report the draft genome sequence of this bacterium. Sequencing yielded a 3.23-Mb genome and 2,967 protein-coding sequences.
RESUMO
This study aimed to evaluate lactic acid bacteria isolates from Saanen goats' milk for probiotic attributes, thereby determining their potential as direct-fed microbials for goats. Isolates were identified using API 50CH system, 16S rDNA sequencing and matrix-assisted laser desorption ionization-time of flight mass spectrometry. All 17 isolates obtained were identified as Lactobacillus plantarum except one identified as Pediococcus acidilactici. Four isolates identified as L. plantarum (Accession numbers KJ026587.1, KM207826.1, KC83663.1 and KJ958428.1) by at least two of the techniques used and isolate 17 differently identified by all the methods used were selected as representatives and then screened for probiotic properties. These isolates displayed phenotypic probiotic attributes including tolerance to acid and bile salts, ability to adhere to intestines and possession of antagonistic activities against Proteus vulgaris, Staphylococcus aureus, Salmonella typhimurium, Pseudomonas aeruginosa and Escherichia coli. The lactic acid bacteria isolated from Saanen goats' milk showed potential to be used as sustainable probiotics in goats' industry. Successful use of probiotics in animals depends upon availability of appropriate isolates originating from the specific host animal. This study is a positive contribution towards identification of isolates with potential for formulation as direct-fed microbials for South African Saanen goats.
