Biosynthesis of Long Chain Alkyl Diols and Long Chain Alkenols in Nannochloropsis spp. (Eustigmatophyceae)

Synthesis of long-chain alkyl and alkenyl bromides.

Long-chain alkyl and alkenyl bromides are obtained in quantitative yields by the reaction of methane-sulfonates with anhydrous magnesium bromide in absolute ether; cis-trans isomerization of double bonds does not occur.

Extension of Linear Isotherm Regularity to Long Chain Alkanes

In this work, we consider each normal alkane as a hypothetical mixtureof methyland methylene groups, in which the interaction potential of each pair is assumed to be the average effective pair potential. Then, the LIR equation of state (EOS) is extended for such a hypothetical mixture. Also, three basic compounds, namely, propane, n-butane and cyclohexane, are used to obtain the contributio...

Genes involved in long-chain alkene biosynthesis in Micrococcus luteus.

Aliphatic hydrocarbons are highly appealing targets for advanced cellulosic biofuels, as they are already predominant components of petroleum-based gasoline and diesel fuels. We have studied alkene biosynthesis in Micrococcus luteus ATCC 4698, a close relative of Sarcina lutea (now Kocuria rhizophila), which 4 decades ago was reported to biosynthesize iso- and anteiso-branched, long-chain alken...

Effect of growth temperature on the long-chain diols and fatty acids of Thermomicrobium roseum.

Long-chain 1,2-diols constitute the hydrophobic backbone of membrane lipids (replacing glycerolipids) in the thermophilic eubacterium Thermomicrobium roseum. The effects of incubation temperature on chain length and chain branching of diols and fatty acids were investigated. The percentage of branched chains decreased, and chain length increased slightly, with increased growth temperatures.
