The integration of batch fermentation and membrane-based pervaporation process in a membrane bioreactor (MBR) was studied to enhance bioethanol production compared to conventional batch fermentation operated at optimum condition. For this purpose, a laboratory-scale MBR system was designed and fabricated. Dense hydrophobic Polydimethylsiloxane (PDMS) membrane was used for pervaporation. For fer...

 Effects of inoculation level (4 or 8-fold compared to standard inoculation) and order (standard inoculation before fermentation and 3-fold inoculation at the end of fermentation = 1+3, Two-fold inoculation before fermentation and the same at the end of fermentation = 2+2, 2+6, 4-fold before fermentation = 4, 4+4, and 8) of culture inoculums containing probiotics on viscosity, phase separation,...

The optimum fermentation times of black tea manufactured by two systems of Orthodox and CTC (cut, tear & curl) were investigated by measuring the quality parameters of black tea, like: theaflavin, thearubigin, highly  polymerized substances and total liquid colour during the fermentation stage. Optimum fermentation times from the beginning of fermentation were determined to be 60 min and 15...

the combined effects of inoculation level (4 or 8-fold compared to standard inoculation) and sequence (standard inoculation before fermentation and 3-fold inoculation at the end of fermentation=1+3, two-fold inoculation before fermentation and the same at the end of fermentation=2+2, 2+6, 4-fold before fermentation=4, 4+4, and 8) of culture inoculum containing probiotics on biochemical and micr...

the aim of this study was evaluation of the effect of controlled fermentation of lactobacillus plantarum on sensory properties and staling of semi-loaf wheat bread. for this purpose, the effect of fermentation times (8, 16, 24 h) and sugar contents (0.5, 1, 1.5%) on activity of mentioned starter in fermentation of wheat flour (with 76% extraction rate) in a split plot design were examined. afte...

In recent decades, olive oil consumption has almost tripled worldwide. Olive production is linked with the of enormous amounts mill wastewater, main by-product derived from three-phase mills. Due to environmental risks wastewater disposal, management and valorization specific waste stream great importance. This work focuses on thermophilic dark fermentation in batch reactors, targeting pH optim...

Food wastes represent one third of all food produced worldwide. It is crucial to both prevent the production waste and recover wasted fraction with aim valorizing it. In this context, conversion organic municipal solid (OFMSW) into bioH2 by dark fermentation (DF) an important technology valorize these renewable fuel. Nevertheless, DF OFMSW needs be optimized for critical operational parameters....
