Hyperconjugative, steric, and electrostatic effects were evaluated as possible sources of the helicity in linear perfluorinated alkanes through analysis of natural bond orbitals and classical electrostatics. Contrary to previous rationalizations, which indicate dominating steric or electrostatic effects, this analysis indicates that hyperconjugative stabilization through σCC →σ*CF interactions ...
Alcanivorax sp. strain NBRC 101098 was isolated from seawater in Japan. Strain NBRC 101098 is able to degrade various types of n-alkanes. Here, we report the complete genome of strain NBRC 101098.
Electron diffraction measurements on epitaxially grown crystals of orthorhombic n-hexatriacontane, n-C(36)H(74), give evidence for the chain-defect mechanism for linear chain melting. The derived structural model is also in accord with recent spectroscopic studies of odd-chain n-alkanes, and the diffraction data specifically exclude models based on helices or rigid chain rotors. Stability of a ...
(212 words) 1 2 Vibrio furnissii M1 was recently reported to biosynthesize n-alkanes when grown on 3 biopolymers, sugars or organic acids (Park, M. the present study, V. furnissii M1 was subjected to genomic analysis and studied 5 biochemically. The sequence of the 16S rRNA gene and repetitive (REP)-PCR showed 6 that V. furnissii M1 was not identical to other V. furnissii strains tested, but th...
This work puts forward a toolkit that enables the conversion of alkanes by Escherichia coli and presents a proof of principle of its applicability. The toolkit consists of multiple standard interchangeable parts (BioBricks)(9) addressing the conversion of alkanes, regulation of gene expression and survival in toxic hydrocarbon-rich environments. A three-step pathway for alkane degradation was i...
Soluble butane monooxygenase (sBMO), a three-component di-iron monooxygenase complex expressed by the C(2)-C(9) alkane-utilizing bacterium Thauera butanivorans, was kinetically characterized by measuring substrate specificities for C(1)-C(5) alkanes and product inhibition profiles. sBMO has high sequence homology with soluble methane monooxygenase (sMMO) and shares a similar substrate range, in...
The aim of this study was to compare the n-alkanes and the ytterbium (Yb)/faecal index techniques as two methods for estimating the herbage intake of dairy cows fed indoors on different herbage : supplement ratios and feeding levels. The supplement was a mixture of maize silage and soyabean meal (ratio of 87 : 13 on a dry matter (DM) basis). In all, four treatments were studied. The herbage : s...
Measurements of biological O(2) demand showed that normal alkanes containing up to 44 carbon atoms were metabolized by microorganisms.
