H����� V., M������ K., R������� M. (2004): Modern method of lactic acid recovery from fermentation broth. Czech J. Food Sci., 22: 87–94. Electrodialysis was used for lactic acid recovery from fermentation broth. In the first step, lactate was recovered and concentrated by desalting electrodialysis, and the second step was electroconversion of lactate to lactic acid by water-splitting electrodia...

Production of lignolytic enzymes by the mushroom fungus Stereum ostrea in liquid medium under conditions of vegetative growth was examined for 10 days in comparison to the reference culture Phanerochaete chrysosporium. Though growth and secretion of extracellular protein by S. ostrea were comparable to those of P. chrysosporium, yields of laccase enzyme by S. ostrea were higher than laccase tit...

The environmental issues associated with residual colour in textile efnuents have posed a major challenge to environmental scientists as well as the textile colouration processors. The requirements to remove colour from textile efnuent on si te prior to discharge to sewer have been progressively tightened due to increased public complaints about coloured watercourses. Dyes are highly dispersibl...

A potential lignolytic fungus, Stereum ostrea was analysed for the decolourisation of industrial effluents discharged from rayon pulp mills. The colour removal was from 5580.85 to 2690.05 CU during 40 days of incubation time. The laccase activity during the decolorization process was increased up to 20 day (862.77 U/L) and after that it was very low. Chemical bleaching was effective and showed ...

the main objective of this study was to investigate the effi ciency of biological treatmentof azo dye-containing wastewater with a sequencing batch reactor system, followed by ultrafi ltration.the performance of the system was quantifi ed by measuring the chemical oxygen demand and azo dyeconcentration. the biodegradation was carried out under combined alternating anaerobic and aerobiccondition...
