The wax ester and constituent fatty alcohol and fatty acid compositions of the psychrophilic bacterium Micrococcus cryophilus grown at 1 or 20 °C have been analysed using packed column and capillary gas-liquid chromatography. The major wax esters were C36, C34 and C32, with a large percentage of mono- and di-unsaturated wax esters (91 to 99 % of the total). When the growth temperature was lowered from 20 to 1 °C the average chain length of the wax esters decreased and their unsaturation increased. The average chain length of the saturated wax esters was less than that of the unsaturated wax esters. The fatty alcohols and fatty acids of the wax esters were mainly C18, with smaller amounts of Cl6, and were straight chain saturated and mono-unsaturated with cis double bonds at positions ∆9 and ∆11. The fatty alcohols had a shorter average chain length and were more saturated than the fatty acids, and contained a higher proportion of cis ∆11 unsaturated isomers. The combination of fatty alcohols and
Hydrocarbon containing compounds like diesel, crude oil and petrol cause environmental pollution. Hydrocarbon contaminated sites contain large amount of microbial community adapted for utilizing these compound as a source of carbon and other metabolic activities. A study was conducted in order to isolate the micro-organism from hydrocarbon contaminated sites for petroleum degradation. The soil sample was collected from the bus terminal of Punjab University, Lahore. The isolate (Micrococcus sp.) was characterized microbiologically by using microbiological techniques such as staining and biochemical testing based on Bergey’s manual. Isolated organism has an ability to degrade the petrol as well as paraffin wax as a sole carbon source. This ability shows clear evidence that genome of this isolate harbors gene for degradation. By combined both properties, we can reduce petroleum product from hydrocarbon impacted environment.   Key words: Petrol degradation, paraffin wax, biochemical
An attempt has been made to develop the genetics of Micrococcus radiodurans by analysing transformation and conjugation processes. The nature of the transformation process in M. radiodurans was studied by investigating the effect of various factors on the efficiency of transformations. M. radiodurans can be transformed by exogenous DNA at a frequency of 10 without special treatment. The presence of glucose or amino acids during growth or transformation had no significant effect on the frequency. Treatment of recipient cells with calcium chloride at the optimum concentration of 30 mM increased the frequency of transformation up to 10,000-fold for some markers, e.g. rifampicin resistance. Magnesium and strontium ions could not replace calcium while sine ions completely inhibited transformation. The efficiency of transformation was also affected by the pH, pH 7.0 being the most effective with CaCl-treated cells. The minimum time required for phenotypic expression varied wiith different markers, ...

The disc diffusion test with penicillin G and the cloverleaf method could not separate beta-lactamase-positive from beta-lactamase-negative strains. Two applications of the chromogenic cephalosporin test, using uninduced strains and strains grown on blood agar plates, gave a large number of false negative and false positive results. False negative reactions were most common among uninduced strains, while the false positive reactions were most often recorded for Staphylococcus saprophyticus. A high degree of efficiency was recorded for the nitrocefin spot test, using induced strains grown on antibiotic susceptibility agar, and for the starch-iodine plate method. The starch-iodine plate with methicillin as inducer gave the most reliable results.}, ...

A preparation of ATPase from the membranes of Micrococcus lysodeikticus, solubilized and more than 95% pure, showed two main bands in analytical polyacrylamide gel electrophoresis. They did not correspond to isoenzymes because one band could be converted into the other by exposure to a mildly alkaline pH value. The conversion was paralleled by changes in molecular weight, circular dichroism and catalytic properties. Denaturation by pH at 25 degrees C was followed by means of circular dichroism, ultracentrifugation and polyacrylamide gel electrophoresis. A large conformational transition took place in the acid range with midpoints at about pH = 3.6 (I = 10(-4) M), 4.3 (I = 0.03 M) and 5.3 (I = 0.1 M). The transition was irreversible. Strong aggregation of the protein occurred in this range of pH. The final product was largely random coil, but even at pH 1.5 dissociation into individual subunits was not complete. However, partial dissociation took place at pH 5 (I = 0.028 M). At this pH value the enzyme

The culturability of several actinobacteria is controlled by resuscitation-promoting factors (Rpfs). These are proteins containing a c. 70-residue domain that adopts a lysozyme-like fold. The invariant catalytic glutamate residue found in lysozyme and various bacterial lytic transglycosylases is also conserved in the Rpf proteins. Rpf from Micrococcus luteus, the founder member of this protein family, is indeed a muralytic enzyme, as revealed by its activity in zymograms containing M. luteus cell walls and its ability to (i) cause lysis of Escherichia coli when expressed and secreted into the periplasm; (ii) release fluorescent material from fluorescamine-labelled cell walls of M. luteus; and (iii) hydrolyse the artificial lysozyme substrate, 4-methylumbelliferyl-β-d-N,N,N-triacetylchitotrioside. Rpf activity was reduced but not completely abolished when the invariant glutamate residue was altered. Moreover, none of the other acidic residues in the Rpf domain was absolutely required for ...
Micrococcus luteus is a Gram-positive, to Gram-variable, nonmotile, Coccus, saprotrophic bacterium that belongs to the family Micrococcaceae.
Dormancy among nonsporulating actinobacteria is now a widely accepted phenomenon. In Micrococcus luteus, the resuscitation of dormant cells is caused by a small secreted protein (resuscitation-promoting factor, or Rpf) that is found in spent culture medium. Rpf is encoded by a single essential gene in M. luteus. Homologs of Rpf are widespread among the high G + C Gram-positive bacteria, including mycobacteria and streptomycetes, and most organisms make several functionally redundant proteins. M. luteus Rpf comprises a lysozyme-like domain that is necessary and sufficient for activity connected through a short linker region to a LysM motif, which is present in a number of cell-wall-associated enzymes. Muralytic activity is responsible for resuscitation. In this report, we characterized a number of environmental isolates of M. luteus, including several recovered from amber. There was substantial variation in the predicted rpf gene product. While the lysozyme-like and LysM domains showed little ...

Discovered in 1956 by A. W. Anderson when trying to completely sterilize food through radiation, Deinococcus radiodurans (ATCC number 13939) is one of the extremophilic bacterium of the world. Though it was first called Micrococcus radiodurans, the genus Micrococcus did not quite match all of the characteristics that this microbe exhibited, therefore it was placed in its own genus Deinococcus which most closely matches the genus Thermus. The Greek phrase deino kokkus means terrible berry while the Latin words radius and durare means radiation surviving producing the name Deinococcus radiodurans.. A. W. Anderson and his coworkers were working on a way to sterilize food by using high doses of gamma radiation. They exposed a tin can of meat to a dose of radiation that was thought to be strong enough to kill all known forms of life. However, the meat still spoiled. Puzzled that anything could survive such a dose, they investigated only to find that the microbe D. radiodurans was the cause. This ...

Hydrocarbon utilizing bacteria were isolated from diesel impacted sites at the University of Port Harcourt using the vapour phase transfer method. The isolates were identified as Bacillus, Pseudomonas, Acinetobacter, Serratia, and Micrococcus species. Examination of cultures supplemented with glucose revealed that the total viable counts ranged from 1.7 x 104 to 5.9 x 105 cfu/ml. For cultures supplemented with kerosene the total viable counts ranged from 1.18 x 104 to 3.1 x 105 cfu/ml. Bacillus spp. and Micrococcus spp. gave the highest and lowest counts respectively in both media types within 96 h. The other isolates had counts in between these ranges in the respective supplemented media. The growth of the isolates in mineral salts solution supplemented with glucose or kerosene resulted in turbidity of the broth as compared to clear media solutions in controls. Higher turbidity was recorded in media supplemented with glucose than kerosene, and this was reflected in the total viable counts ...
Using the selective fractionation technique, a group of researchers at Brazils National Synchrotron Radiation Laboratory (LNLS) in Campinas were able to select silver nanoparticles of different sizes obtained from the same batch chemical reaction. They then evaluated the effect of these nanoparticles on different bacterial strains: Escherichia coli, Staphylococcus aureus, Staphylococcus epidermis and Micrococcus lysodeikticus. They found that smaller nanoparticles inhibited the growth of these bacteria more effectively than larger ones. The results of this work, Size-selective silver nanoparticles: future of biomedical devices with enhanced bactericidal properties, are featured on the cover of issue No. 33 of the Journal of Materials Chemistry.. Several scientific challenges must still be solved before silver nanoparticles can be converted into drugs. One of these challenges is in their toxicity, since it is necessary to ascertain how these nanoparticles interact with living cells, explains ...

abstract = {BACKGROUND: Two NF-kappaB signaling pathways, Toll and immune deficiency (imd), are required for survival to bacterial infections in Drosophila. In response to septic injury, these pathways mediate rapid transcriptional activation of distinct sets of effector molecules, including antimicrobial peptides, which are important components of a humoral defense response. However, it is less clear to what extent macrophage-like hemocytes contribute to host defense. METHODOLOGY/PRINCIPAL FINDINGS: In order to dissect the relative importance of humoral and cellular defenses after septic injury with three different gram-positive bacteria (Micrococcus luteus, Enterococcus faecalis, Staphylococcus aureus), we used latex bead pre-injection to ablate macrophage function in flies wildtype or mutant for various Toll and imd pathway components. We found that in all three infection models a compromised phagocytic system impaired fly survival--independently of concomitant Toll or imd pathway activation. ...

In this study, we examined the bacterial communities on the upper arms of 8 volunteers before and after inoculation with H. ducreyi. The microbiomes were similar to those of reported forearm microbiomes (1, 2, 5). At preinfection, we found the skin of the deltoid region to be largely dominated by Actinobacteria, Firmicutes, Proteobacteria, and Bacteroidetes. Similarly, a recent study on two human volunteers who were asked not to bathe 3 days prior to sampling identified these 4 phyla and Cyanobacteria on the upper arm (38). In contrast, the same study found low levels of Propionibacterium and Staphylococcus on the upper arm, whereas these genera comprised a large proportion of our volunteers microbiomes. Both studies identified moderate levels of Corynebacterium on the upper arm, and we found moderate levels of Streptococcus, Paracoccus, and Micrococcus species. We did not ask our participants to refrain from bathing prior to infection; perhaps hygiene and person-to-person variations ...
Recent work by Dimtroglou et al (2007) demonstrated that Bio-Mos significantly reduced the bacterial load in the gut of both rainbow trout and sea bream by reducing the total aerobically cultivated bacteria. In the case of sea bream, the percentage contribution of the various aerobically cultivated bacterial families to the total count was not significantly altered between the Bio-Mos fed fish and the controls. However, in the case of rainbow trout, the Bio-Mos fed fish had reduced numbers of Micrococcus spp., Staphylococcus spp., Aeromonas/ Vibrio spp and other unidentified Gram + bacteria. Increases were also seen in Acinetobacteria spp., Pseudomonads spp. and Enterobacteria spp ...
