Sulfate-reducing bioreactors for sulfide production are the initial stage of processes targeting elemental sulfur recovery from sulfate-rich effluents. In this work, principal reactions involved in glycerol fermentation and sulfate reduction using its products as electron donors were assessed together with their specific consumption/production rates. A battery batch activity tests without perfo...

The production of biodiesel from rapeseed oil methyl ester leaves glycerol (synonym: glycerine, 1,2,3-propanetriol) as a valuable by-product and a promising feed supplement for farm animals. This thesis provides information about the supplemental feeding with glycerol to dairy cows in early lactation and to young calves, and describes the fate of glycerol entering the rumen and the impact of gl...

Polyhydroxyalkanoates (PHAs) are a group of biopolymers used as an alternative to petroleum-based synthetic plastics. Their industrial application is not widely available due production cost constraints, mainly from raw materials for carbon sources. This research focuses on selecting Bacillus strain lipid-containing wastewater that can produce PHAs crude glycerol and investigating the optimum c...

Biodiesel production through transesterification results in a large quantity of crude glycerol as byproduct, the utilization which is technically and economically challenging. Because ability to efficiently process wet feedstocks, supercritical water gasification (SCWG) utilized this study convert into hydrogen-rich syngas. A significant challenge addressed decomposition routes different hetero...

As β-glucosidases represent the major bottleneck for industrial degradation of plant biomass, great efforts are being devoted to discover both novel and robust versions these enzymes, as well develop efficient inexpensive ways produce them. In this work, raw glycerol from chemical production biodiesel was tested carbon source fungus Talaromyces amestolkiae with aim producing enzyme β-glucosidas...
