Influence of nitrogen rate, harvest frequency, lower leaf management, and chemical topping on mammoth cultivars of flue-cured tobacco
… 6 more suckers than all other treatments. The fatty alcohol / maleic hydrazide treatment produced 380 kg ha⁻¹ higher yields and grade indices lower than the hand-topped control in 1987. Above normal nitrogen rate, 3 or 5 time harvest, removal of 4 to 6 leaves at topping or via senescence, and …

Pathway optimization and engineering for biofuel production
… pathway using a heterologously expressed fatty acid synthase coupled with a wax ester synthase. In this reaction, the esterification of a fatty acyl-CoA and fatty alcohol catalyzed by the wax ester synthase produces free fatty acid ethyl esters, otherwise known as biodiesel. Only initial …

Synthesis and performance of novel azo initiators with special reference to emulsion polymerisation
… when reacted with straight-chain aliphatic alcohols. These esters are called 'esters A' and 'esters B', respectively. Surprisingly, the esters A were found to act as effective initiator/stabilisers for the emulsion polymerisation of styrene in the absence of conventional surfactant. …

Detergent effects on disinfectant susceptibility of Escherichia coli and listeria monocytogenes attached to stainless steel
… alkyl sulphate (SAS) by 0.51 Log10 cfu ml-1 and fatty alcohol ethoxylate (FAE) by 0.96 Log10 cfu ml-1. No change in susceptibility was observed with sodium dodecyl sulphate (SDS), sodium lauryl ethyl sulphate (SLES) or polyethoxylated alcohol (PEA). L. monocytogenes became significantly less …

Functionality And Role Of Different Fatty Alcohols In Topical O/W Cream Formulation
Fatty alcohols are excipients that are abundantly used in various pharmaceutical formulations. The objective of the present study was to evaluate the impact of incorporating different fatty alcohols on microstructural and formulation characteristics of topical o/w clotrimazole cream formulation. …

Metabolic Profiling of Genetically Modified Potato Periderm Tissues
… in cross-linking polysaccharides and lignin. Fatty alcohol/ω-hydroxyacid hydroxycinnamoyl transferase (FHT) is a BADH acyltransferase responsible for the synthesis of akyl-ferulates that is necessary for suberin biosynthesis. Periderm from <em>FHT</em>-RNAi tubers showed a significant decrease …

Structural and kinetic studies of surfactant and phospholipid monolayers at the air/liquid interface using sum-frequency generation spectroscopy
… hair conditioner model, consisting of a fatty alcohol and a long chain quaternary ammonium salt, self-assembled from solution onto a silica surface (which serves as a very approximate model of the hair surface). SFG was used to investigate and the effects of temperature and ionic strength …

Charakterisierung von Acyl-CoA-Reduktasen
cDNA sequences encoding fatty acyl-CoA reductases were cloned from the uropygial glands of barn owl (Tyto alba), domestic chicken (Gallus gallus domesticus) and domestic goose (Anser anser domesticus). Heterologous expression studies in Saccharomyces cerevisiae showed that they encode membrane …
