Ultrafiltrative separation of rhamnolipid from culture medium
Classic methods of biosurfactant separation are difficult and require large amounts of organic solvents, thus generate high amounts of waste. This work presents and discusses in detail an original procedure to separate rhamnolipid from fermentation broth using high performance membrane techniques. Due to the unique properties of surface active agents, such as capability of forming aggregates ab...
متن کاملEnhancement of Pseudomonas Aeruginosa Growth and Rhamnolipid Production Using Iron-Silica Nanoparticles in Low-Cost Medium
The application of iron-silica (Fe-Si) nanoparticles for the enhancement of the Pseudomonas aeruginosa growth and rhamnolipid production in molasses medium was studied. The experiments were designed based on the response surface method (RSM) to optimize growth and rhamnolipid production. The concentration of nanoparticles and the time required to add nanoparticles to culture medium were conside...
متن کاملA Culture Medium from Groundnut Meal
Acton el al. (1932) used a vegetable medium from a green variety of mung dal (Phaseolus mungo) for cultivation of the intestinal bacteria. Brewer (1943) suggested a mixture of soyabean and cotton seed or peanut meal for the preparation of a general purpose media using sodium sulphide as an activator; the sodium sulphide would readily generate sulphuretted hydrogen which by lowering the pH of th...
متن کاملNew blood culture medium.
A growth medium with a specific oxidation-reduction potential containing peptone, dextrose, sodium succinate, sodium lactate, gelatin, sodium bicarbonate and blue tetrazolium, an indicator dye, in a tris(hydroxymethyl)aminomethane buffer was used to detect the presence of microorganisms in blood. The procedure involved the introduction of blood (and bacteria) into the growth medium with the dye...
متن کاملCharacterization f Ribonucleases from JSec Culture Medium of Lentinus edocies
g]ycoproteins and their amino acid compesitions are significantly different from that of RNase Le2. In addition to these enzyines, a guanylic acid-specific RNase with a molecular mass 13 kDa was panially purified. Since RNase Le2, which has yery similar IVLterminat sequence to RNase Le 37 and RNase Le 45, was not excreted from the mycelia, the analysis of the structures of these two excreted RN...
