Ensign, Jerald C. (University of Illinois, Urbana), and R. S. Wolfe. Nutritional control of morphogenesis in Arthrobacter crystallopoietes. J. Bacteriol. 87:924-932. 1964.-Arthrobacter crystallopoietes exhibits the cyclic, morphological variation which is a characteristic of this genus. A simple chemically defined medium was developed in which this organism is restricted to growth and division ...

because of the importance of microbial metabolites of cholesterol as precursors in the synthesis of steroidal drugs, we decided to study the ability of arthrobacter simplex to degrade cholesterol. arthrobacter simplex cleaves the side chain of cholesterol in the presence of 2,2'-dipyridyl and produces 4-androstene-3,17- dione (ad) and androsta- 1,4-diene-3,17-dione(add). two other intermed...

Arthrobacter agilis strain L77, is a plant growth promoting and cold active hydrolytic enzymes producing psychrotrophic bacterium, isolated from Pangong Lake, a subglacial lake in north western Himalayas, India. Genome analysis revealed metabolic versatility with genes involved in metabolism and cold shock adaptation, utilization and biosynthesis of diverse structural and storage polysaccharide...

We have constructed a plasmid to express and secrete dextranase in the oral bacterium Streptococcus gordonii. The dextranase gene from Arthrobacter sp. strain CB-8 was linked to a promoter and a DNA sequence encoding the signal peptide of Streptococcus downei glucosyltransferase I (gtfI) followed by the Escherichia coli rrnBt1t2 terminator and inserted in the shuttle vector pVA838. S. gordonii ...

Among the facultative bacteria capable of growth on mesquite wood which were isolated from the asceptically dissected hind-gut of the termite Reticulitermes hesperus were two strains of Bacillus cereus, one strain each of Arthrobacter, Alcaligenes and Serratia, and a very small Gram-negative fermentative rod. The B. cereus strains, the Serratia marcescens strain and the Arthrobacter sp. grew we...

Three bacterial strains of marine origin were isolated during a screening for biosurfactants among n-alkane degrading microorganisms. One strain-identified as Alcaligenes sp. MM1-produced a novel glucose lipid. In the case of Arthrobacter sp. EK 1 the well-known trehalose tetraester was found as major component. From another pure culture classified as Arthrobacter sp. SI 1, extracellular emulsi...

A lipase producer psychrophilic microorganism isolated from Arctic sample was studied. The genomic DNA of the isolate was extracted using modified CTAB method. Identification of the isolate by morphological and 16S rRNA sequence analysis revealed that the isolate is closely related to Arthrobacter gangotriensis (97% similarity). A. gangotriensis was determined as positive lipase producer based ...

A bacteriophage which reproduces on Arthrobacter globiformis ATCC 8010 was isolated from soil. This bacteriophage, designated phiAG8010, propagates either in soft agar or broth cultures of the host. Because of a slow adsorption rate, neither the latent period nor burst size was determined. The mature virion belongs to Bradley's group B and exhibits a hexagonal head measuring 69 nm (length) by 6...
