Serratia montpellierensis sp. nov., Isolated from Laboratory-Reared Parasitic Wasps Psyttalia lounsburyii Silvestri and Psyttalia ponerophaga Silvestri (Hymenoptera: Braconidae)
Curr Microbiol. 2024 Apr 18;81(6):146. doi: 10.1007/s00284-024-03666-0.ABSTRACTTwo strains of bacteria, PsyLou2AT and PsyPon4B, were isolated from adult braconid wasps Psyttalia lounsburyii and Psyttalia ponerophaga, respectively. These laboratory-reared wasps were investigated as agents for biological control of the olive fruit fly, Bactrocera oleae. Analysis of 16S rRNA genes of the two isolates demonstrated that they were highly related and belonged to the genus Serratia. Genomic sequencing of these isolates revealed genomes of 5,152,551 bp and 5,154,385 bp for PsyLou2AT and PsyPon4B, respectively, and both genomes had ...

Nitrospirillum viridazoti sp. nov., an Efficient Nitrogen-Fixing Species Isolated from Grasses
Curr Microbiol. 2024 Apr 17;81(6):144. doi: 10.1007/s00284-024-03665-1.ABSTRACTA group of Gram-negative plant-associated diazotrophic bacteria belonging to the genus Nitrospirillum was investigated, including both previously characterized and newly isolated strains from diverse regions and biomes, predominantly in Brazil. Phylogenetic analysis of 16S rRNA and recA genes revealed the formation of a distinct clade consisting of thirteen strains, separate from the formally recognized species N. amazonense (the closest species) and N. iridis. Comprehensive taxonomic analyses using the whole genomes of four strains (BR 11140T =...

Genomic Approach of Listeria monocytogenes Strains Isolated from Deli-Meats in Mexico
Curr Microbiol. 2024 Apr 17;81(6):145. doi: 10.1007/s00284-024-03680-2.ABSTRACTListeria monocytogenes is a foodborne pathogen that causes listeriosis worldwide. In México, L. monocytogenes has been identified as a hazard of deli-meats. However, the genomic analysis that supports the transmission of L. monocytogenes strains via deli-meats and its role as a source for virulence and resistance genes is lacking. Here, we present four high-quality genome drafts of L. monocytogenes strains isolated from deli-meats in Mexico. In silico typing was used to determine the serotype, lineage, clonal complexes (CC), and multilocus sequ...

Optimization of Recombinant Protein Production in Synechococcus elongatus PCC 7942: Utilizing Native Promoters and Magnetic Fields
This study aimed to enhance RP production by integration of native promoters and magnetic field application (MF) in S. elongatus PCC 7942. The psbA2 promoter, which responds to stress conditions, was chosen for the integration of the ZsGreen1 gene. Results indicated successful gene integration, affirming prior studies that showed no growth alterations in transgenic strains. Interestingly, exposure to 30 mT (MF30) demonstrated a increase in ZsGreen1 transcription under the psbA2 promoter, revealing the influence of MF on cyanobacterial photosynthetic machinery. This enhancement is likely attributed to stress-induced shifts ...

Antimicrobial and Probiotic Potential of Lactobacilli Associated with Traditional Fermented Beverages
In this study, we investigated the antimicrobial and probiotic potential of lactobacilli isolated from fermented beverages produced traditionally by ethnic groups in Northeast India. Out of thirty Lactobacilli, fifteen exhibited strong antimicrobial activity against Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter aerogenes with significant anti-biofilm and anti-quorum sensing activity. These isolates also showed characteristics associated with probiotic properties, such as tolerance to low pH and bile salts, survival in the gastric tract,...

Crucifer Lesion-Associated Xanthomonas Strains Show Multi-Resistance to Heavy Metals and Antibiotics
In this study, multi-resistance to heavy metals and antibiotics were evaluated in local Xanthomonas campestris pv. campestris (Xcc) and co-isolated Xanthomonas melonis (Xmel) strains from infected crucifer plants in Trinidad. Resistance to cobalt, cadmium, zinc, copper, and arsenic (V) was observed in both Xanthomonas species up to 25 mM. Heavy metal resistance (HMR) genes were found on a small plasmid-derived locus with ~ 90% similarity to a Stenotrophomonas spp. chromosomal locus and a X. perforans pLH3.1 plasmid. The co-occurrence of mobile elements in these regions implies their organization on a composite transposon-l...
