Previous studies showed that Arthrobacter pyridinolis can transport and utilize d-glucose only after prior growth on certain Krebs cycle intermediates. In contrast, we found that d-fructose was taken up and metabolized by A. pyridinolis without special prior conditions of growth. d-Fructose was first converted to d-fructose-1-phosphate by a phosphoenolpyruvate (PEP):D-fructose phosphotransferas...

Different methods have been developed for mineral exploration so far, amongst which biological-based methods known as geomicrobiological studies are of the most recent ones. Geomicrobiology as an interdisciplinary approach has achieved great progresses during the past two decades and involves the study of microbes in a number of fundamental geological processes, both in the past and present. Th...

Terephthalic acid is an important industrial chemical but its production typically generates 3–10 tons of wastewater, which is a significant source of pollution. Although recent research has shown that terephthalic acid can be degraded by physical and chemical methods, these methods are complex and expensive. Microbial degradation of terephthalic acid is a popular alternative because it is envi...

Within a screening for biosurfactants we could isolate various n-alkanes utilizing marine bacteria which were capable of synthesizing glycolipids. One strain was identified as Arthrobacter sp. EK 1 which produced trehalose lipids. After purification by column and thick layer chromatography the main fraction, an anionic 2,3,4,2'-trehalose tetraester, was obtained. The chain lengths of fatty acid...
