We report the development of a plasmid-mediated transformation system for Arthrobacter sp. NRRLB3381, using the Streptomyces cloning vector pIJ702. Our procedure gives a transformation frequency of 10(3)/micrograms of plasmid DNA. In addition we have explored the expression of the Arthrobacter ermA gene in Streptomyces lividans and Escherichia coli, and shown that the ermA promoter is recognize...

We examined the stomach contents of 21 specimens of Mabuya agilis (Sauria; Scincidae) collected during February 2001 at the restinga habitat of Praia do Sul, in Ilha Grande, RJ, Brazil. Diet was composed of various types of small arthropods, with no plant material being eaten. Spiders were the most important items in the diet, followed by orthopterans. Apart from the absence of isopterans, the ...

The historically-famous Lotus Fortress site, a deep 1.5-3.0-meter-high, 200-meter-long horizonal notch high up in near-vertical sandstone cliffs comprising the Cretaceous Jiaguan Formation, has been known since the 13th Century as an impregnable defensive position. The site is also extraordinary for having multiple tetrapod track-bearing levels, of which the lower two form the floor of part of ...

Trace fossils provide the only records of Early Cretaceous birds from many parts of the world. The identification of traces from large avian track-makers is made difficult given their overall similarity in size and tridactyly in comparison with traces of small non-avian theropods. Reanalysis of Wupus agilis from the Early Cretaceous (Aptian-Albian) Jiaguan Formation, one of a small but growing ...

Gasdorf, Helen J. (Northern Regional Research Laboratory, Peoria, Ill.), R. G. Benedict, M. C. Cadmus, R. F. Anderson, and R. W. Jackson. Polymer-producing species of Arthrobacter. J. Bacteriol. 90:147-150.1965.-Two slime-producing microorganisms, designated as NRRL B-1973 and NRRL B-1797, were isolated from a Guatemalan soil sample. Their morphological and physiological characteristics permit ...

The genus Arthrobacter was established in 1947 by Conn & Dimmick. So far, more than 70 recognized species of the genus Arthrobacter have been certified. Its special functions have been widely known by researchers, such as, in agricultural, in medical, in industrial, and in environmental areas, etc. What deserves to be mentioned is that some species of genus Arthrobacter have showed the function...

Arthrobacter is one of the most prevalent genera of nicotine-degrading bacteria; however, studies of nicotine degradation in Arthrobacter species remain at the plasmid level (plasmid pAO1). Here, we report the bioinformatic analysis of a nicotine-degrading Arthrobacter aurescens M2012083, and show that the moeB and mogA genes that are essential for nicotine degradation in Arthrobacter are absen...

After the initial description of Arthrobacter spp. isolated from clinical specimens in the mid-1990s, very few further reports on Arthrobacter spp. have appeared in the clinical microbiology literature. The aim of the present study was to elucidate the distribution of Arthrobacter spp. and Arthrobacter-like bacteria encountered in clinical specimens by studying 50 consecutively isolated or rece...

Twelve siphoviral phages isolated using Arthrobacter sp. strain ATCC 21022 were sequenced. The phages all have relatively small genomes, ranging from 15,319 to 15,556 bp. All 12 phages are closely related to previously described cluster AN Arthrobacter phages.

A novel desiccation-tolerant, xeroprotectant-producing bacterium, designated strain 4J27(T), was isolated from a Nerium oleander rhizosphere subjected to seasonal drought in Granada, Spain. Phylogenetic analysis based on 16S rRNA gene sequencing placed the isolate within the genus Arthrobacter, its closest relative being Arthrobacter phenanthrenivorans Shep3 DSM 18606(T), with which it showed 9...
