Data on pigments and long-chain fatty compounds identified in Dietzia sp. A14101 grown on simple and complex hydrocarbons

Abstract

This data article provides:An overview of tentatively identified long chain compounds in Dietzia sp. A14101 grown on simple and complex hydrocarbons;Preliminary Identification of pigments in bacterial material obtained from incubation with a hydrocarbon (dodecane, n-C12) as the only carbon and energy source;Some pictures to illustrate the cell surface charge test.

Fatty acids in bacterium Dietzia sp. grown on simple and complex hydrocarbons determined as FAME by GC–MS.

“…1 and Table 1 in Hvidsten et al (2015). These relatively high molecular weight structures were detected at trace amounts and tentatively identified as long-chain FAs and /or short-chain mycolic acids, SCMA.…”

“…The FA profiles showed (1) production of C 16:0 common in all life forms; (2) LCFA with 20 or more carbon atoms, common in Actinomycetes; (3) only low levels of iso-and anteiso-FA (common in Gram-positive, but rarely found in Gram-negative); (4) no PUFA (common in some cyanobacteria); (5) varied amounts of MUFA (common in aerobic bacteria); (6) several cyclopropane-substituted FA (common in Gram-positive bacteria); (7) no short-chain ( 23 carbon atoms) hydroxyl group-substituted FA; (8) several long chain structures were identified tentatively as mycolic acids (C 28-35 ) in trace amounts in all samples ( Table 1 in (Hvidsten et al, 2015). In addition, there was an indication of several ketosubstituted FA present but the amounts were too low to be identified unambiguously thus the data were not included in the total overview.…”

“…Incubations on non-HC sources (PD-glu and I-1) were almost colourless, while the increased production of carotenoid-type pigments (Figs. 2 and 3 and Table 3 in Hvidsten et al (2015)) was obviously coupled to the growth on HC as a sole source of energy and carbon, whether a simple HC-substrate (n-alkane) or a complex HC-mixture (crude oil).…”

“…In short, an anionic surfactant reacts with a dye to produce a chloroform-soluble blue-coloured complex; some illustrative material, Fig. 4a-c) is presented in Hvidsten et al (2015).…”

“…The long-chain compounds with ECL index [23; 28] (the value of 28 was the calibration maximum in the provided software) were identified unambiguously. The compounds with ECL values higher than ECL 28 were identified tentatively on the basis of the mass spectra Table 2 in Hvidsten et al (2015).…”
