Bacterial Predators of Micrococcus luteus in Soil [PDF]

Applied and Environmental Microbiology, 1980
Micrococcus luteus cells died relatively rapidly when they were added to natural soil. Microscopic observation showed that the cells were being physically destroyed by bacterial predators in the soil. Two of these predators were responsible for the initial, main attack, and they were isolated.

A 3D calcium-deficient hydroxyapatite-based scaffold with gold nanoparticles effective against Micrococcus luteus as an artificial bone substitute

Materials & Design, 2022
During implant surgery, microbial contamination of implants is a major issue that must be addressed to avoid acute and chronic post-surgery infection that may result in acute inflammation, a lengthy healing period, and surgical failure.

Reclassification of Micrococcus aloeverae and Micrococcus yunnanensis as later heterotypic synonyms of Micrococcus luteus

International Journal of Systematic and Evolutionary Microbiology, 2019
Micrococcus aloeverae,Micrococcus endophyticus, Micrococcus luteus and Micrococcus yunnanensis are phenotypically and genotypically closely related, and together comprise the M. luteus group. In this study, the taxonomic relationships among Micrococcus aloeverae, M. luteus and M. yunnanensis were re-evaluated by using polyphasic approaches.

Transcription termination factor Rho is essential for Micrococcus luteus [PDF]

Journal of Bacteriology, 1997
The growth of Micrococcus luteus, a soil microorganism that belongs to the high-G+C gram-positive phylogenetic group, is prevented by bicyclomycin, an antibiotic that inhibits the activity of the M. luteus transcription termination factor Rho. A mutant that can grow in 0.3 mM bicyclomycin has a Rho that is insensitive to bicyclomycin and has the single

Negative Correlation between Lipid Content and Antibiotic Activity in Streptomyces: General Rule and Exceptions

Antibiotics, 2020
Streptomycetes are well known antibiotic producers and are among the rare prokaryotes able to store carbon as lipids. Previous comparative studies of the weak antibiotic producer Streptomyces lividans with its ppk mutant and with Streptomyces coelicolor,

Heterogeneity of Intratumoral Microbiota Within the Tumor Microenvironment and Relationship to Tumor Development

Med Research, EarlyView.
Mutual shaping of tumor microbiota and TME. Intratumoral microbiota—comprising diverse bacteria, fungi, viruses, and intracellular organisms—play critical and dynamic roles in shaping the tumor microenvironment (TME). Their spatial and compositional diversity contributes to both intratumoral and intertumoral heterogeneity, influencing immune modulation

Novel High‐Throughput Electrochemical Detection of Staphylococcus Aureus, Bacillus Cereus, or Micrococcus Luteus Using AuNPs@Ti3C2Tz Functionalized with Sandwich Peptides

Small, EarlyView.
This study develops an electrochemical biosensor platform using 16‐channel gold disk electrodes (16‐GDEs) and an AuNPs@Ti3C2Tz for detecting gram‐positive bacteria like Staphylococcus aureus, Bacillus cereus, and Micrococcus luteus. The platform enables a sensitive, high‐throughput method in environmental samples, with no cross‐reactivity. It serves as
