There is currently much interest in the use of natural biosurfactants and bioemulsifiers, mainly cosmetic, pharmaceutical food industries. However, there are no studies on optimization extraction conditions cell-bound biosurfactants. In this work, a biosurfactant with emulsifier properties was extracted from Lactobacillus pentosus cells, under different conditions, characterized.During extraction, most influential independent variable, concerning emulsifying capacity biosurfactant, operation...
The utilization of biosurfactants for the bioremediation contaminated soil is not yet well established, because high production cost biosurfactants. Consequently, it interesting to look new that can be produced at a large scale, and employed sites. In this work, from Lactobacillus pentosus growing in hemicellulosic sugars solutions, with similar composition found trimming vine shoot hydrolysates, were octane. It was observed presence biosurfactant L. accelerated biodegradation octane soil....
Corn steep liquor (CSL) is a liquid byproduct generated by the corn wet-milling industry. This agroindustrial residue obtained when digested with warm water and SO2 in presence of different spontaneously growing microorganisms. The microbial population CSL includes lactic acid bacteria, which are widely known to produce biosurfactants. However, there no information available about possible existence surface-active compounds CSL. In this work surface tension activity was evaluated...
Trace element contamination is one of the main problems linked to quality compost, especially when it produced from urban wastes, which can lead high levels some potentially toxic elements such as Cu, Pb or Zn. In this work, distribution and bioavailability five (Cu, Zn, Pb, Cr Ni) were studied in Spanish composts obtained different feedstocks (municipal solid waste, garden trimmings, sewage sludge mixed manure). The showed total concentrations these elements, cases limited their...
Abstract Previous studies have provided evidence that color measurements enable on site quantification of superficial biofilms, thereby avoiding the need for sampling. In present study, efficiency to evaluate what extent pigment production is affected by environmental parameters such as light intensity, combined nitrogen and nutrient availability, was tested with two cyanobacteria, Nostoc sp. strains PCC 9104 9025, which form biofilms stone. Both were acclimated, in aerated batch cultures 2...
Many studies have investigated the effects of pH, temperature, and salinity on surface-active properties various surfactants, although in most cases variables been studied separately, without considering any interactions between them. In present study, a Box-Behnken factorial design was applied to study biosurfactant produced by Lactobacillus pentosus. The data obtained enabled development second-order model describing interrelationships operational experimental variables, equations...
This study aimed to estimate the bioelectricity production process using a vinasse solution through application of Plackett–Burman and Box–Behnken designs. An electrochemical cell was constructed Arduino measure potential difference between an anode cathode immersed in solution, which is byproduct wine containing organic compounds ions that undergo redox reactions. The design identified most influential variables among eight previously selected (concentration electrolyte, pH, temperature,...
