The earliest report on the bacteriostatic effect of heparin was made by Stoker (1949) who claimed that Staphylococcus aureus was inhibited by heparin only in the presence of protein (pus or trauma blood). Later Warren and Graham (1950) found, in contradistinction to the results of Stoker (1949), that Bacterium 8tewartii and Micrococcus pyogens var. aureus were not inhibited by heparin when grow...

Campbell, J. N. (American Meat Institute Foundation, Chicago, Ill.), James B. Evans, Jerome J. Perry, and C. F. Niven, Jr. Effect of ammonium ion on growth and metabolism of Micrococcus sodonensis. J. Bacteriol. 82:823-827. 1961.-When Micrococcus sodonensis was grown in a synthetic medium deficient in ammonia, large quantities of alpha-keto acids, chiefly alpha-ketoglutaric, accumulated in the ...

BACKGROUND Micrococcus species may cause intracranial abscesses, meningitis, pneumonia, and septic arthritis in immunosuppressed or immunocompetent hosts. In addition, strains identified as Micrococcus spp. have been reported recently in infections associated with indwelling intravenous lines, continuous ambulatory peritoneal dialysis fluids, ventricular shunts and prosthetic valves. CASE PRE...

The need for safe food products has motivated food scientists and industry to find novel technologies for antimicrobial delivery for improving food safety and quality. Controlled release packaging is a novel technology that uses the package to deliver antimicrobials in a controlled manner and sustain antimicrobial stress on the targeted microorganism over the required shelf life. This work stud...

Gaffkya homari, a micrococcus isolated from septicemic lobsters, has an obligate purine requirement (Aaronson, 1956). Further study shows this requirement to be satisfied by several natural purines as well as by several purine analogues. This broad response suggested that G. homari might be useful for studying purine biosynthesis. We wished especially to know whether G. homari utilized 4-amino-...

We present herein an improved assay for detecting the presence of extracellular proteases from microorganisms on agar plates. Using different substrates (gelatin, BSA, hemoglobin) incorporated into the agar and varying the culture medium composition, we were able to detect proteolytic activities from Pseudomonas aeruginosa, Micrococcus luteus and Serratia marcescens as well as the influence tha...

Fermented succulent shoots of bamboo (Bambusa balcooa and Dendrocalamus strictus) are an enriched source of phytosterol. Microorganisms from the ‘soibum exudate’ involved in microbial bioconversion of phytosterol during fermentation of succulent bamboo shoots were isolated and identified as Bacillus subtilis, B. licheniformis, B. coagulans and Micrococcus luteus. Crude phytosterol was purified ...

BACKGROUND Kocuria, established by Stackebrandt et al., previously was classified into Micrococcus. Only two species, K. rosea and K. kristinae are reported to be associated as pathogenic and found with catheter-related bacteremia and acute cholecystitis. CASE PRESENTATION We herein report the first case of brain abscess caused by Kocuria varians, a gram-positive microorganism, in a 52-year-o...

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 amino acid residue change of Asp474 to Gly...
