The marine hydrocarbonoclastic bacterium Alcanivorax borkumensis is well known for its ability to successfully degrade various mixtures of n-alkanes occurring in marine oil spills. For effective growth on these compounds, the bacteria possess the unique capability not only to incorporate but also to

Wax ester-like compounds as biosurfactants produced by Dietzia maris from n-alkane as a sole carbon source.

Ingia / Ingia
The hydrocarbon-degrading bacterium Dietzia maris WR-3 was isolated from a consortium comprising ammonia-oxidizing and denitrifying bacteria derived from marine sediments. Here, we examined biosurfactant production by strain WR-3 when cultured using several different carbon (D-glucose, n -decane, n

The kinetics of oxidation of kerosene Jet A-1 and a kerosene/rapeseed oil methyl ester (RME) mixture (80/20, mol/mol) (biokerosene) was studied experimentally in a jet-stirred reactor at 10 atm and constant residence time, over the temperature range 740-1200 K, and for variable equivalence ratios

Biological surface-active compounds from marine bacteria.

Ingia / Ingia
Surface-active compounds (SACs) are widely used in different industries as well as in many daily consumption products. However, with the increasing concern for their environmental acceptability, attention has turned towards biological SACs which are biodegradable, less toxic and more environmentally
Toxic weed Lantana camara foliage was composted with cow dung in 2:1 and 1:1 ratio (v/v) and changes in physicochemical characteristics, and faecal coliform bacterial population (Escherichia coli and Salmonella) was estimated for 35 d. Results showed a significant increase in total N

Superoleophobic textured copper surfaces fabricated by chemical etching/oxidation and surface fluorination.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala
Ingia / Ingia
We report a convenient route to fabricate superoleophobic surfaces (abridged as SOS) on copper substrate by combining a two-step surface texturing process (first, the substrate is immersed in an aqueous solution of HNO3 and cetyltrimethyl ammonium bromide, and then in an aqueous solution of NaOH and

A Simple Preparation Method for Hydrophilic/Oleophobic Coatings

Ingia / Ingia
This work provides a simple method to prepare a hydrophilic/oleophobic coating, using polyester filter cloth as the substrate, a mixture of three hydrophilic polymers (poly aspartic acid, polyacrylic acid and polyvinyl alcohol) to form the coating, SiO2 with an average particle size of 30 nm to

Superomniphobic and easily repairable coatings on copper substrates based on simple immersion or spray processes.

Ingia / Ingia
Textures that resemble typical fern or bracken plant species (dendrite structures) were fabricated for liquid repellency by dipping copper substrates in a single-step process in solutions containing AgNO3 or by a simple spray liquid application. Superhydrophobic surfaces were produced using a

Formation and analysis of mannosylerythritol lipids secreted by Pseudozyma aphidis.

Ingia / Ingia
Pseudozyma aphidis DSM 70725 was found to be a novel producer of mannosylerythritol lipids (MELs). The MELs were quantified by HPLC. Glucose as carbon source for precultivation supported growth well. By contrast, at concentrations >30 g l(-1) in preculture, subsequent MEL formation in the main
