The aim of this study was to investigate the potential environmental pollution reduction sugar beet processing factory wastewater by biorefinery approach and integration microalgae biomass production. In present study, Chlorella vulgaris cultivated in collected from a at beginning end plant campaign an aerobic bioreactor on laboratory scale under controlled conditions, with air flow 0.4 L/min, ...

A sequencing batch reactor (SBR) inoculated with activated sludge and bioaugmented a dye-decolorizing yeast strain—Yarrowia lipolytica (HOMOGST27AB) was assembled to form yeast-bioaugmented aerobic granular (AGS). The AGS-SBR operated for the treatment of synthetic saline wastewater (12 g L−1) intermittently fed reactive textile dye (Navy Everzol ED) at 25, 15, 7.5 mg L−1. Dye degradation did n...

Ethanol and β-galactosidase production from cheese whey may significantly contribute to minimise environmental problems while producing value from lowcost raw materials. In this work, the recombinant Saccharomyces cerevisiae NCYC869-A3/pVK1.1 flocculent strain expressing the lacA gene (coding for β-galactosidase) of Aspergillus niger under ADHI promoter and terminator was used. This strain show...

Pentachlorophenol (PCP) has been used in the past as a pesticide, herbicide, antifungal agent, bactericide, and wood preservative. Thus, PCP is among the most ubiquitous chlorinated compounds found in groundwater contamination. A former pesticide manufacturing plant located in southern Taiwan has been identified as a PCP spill site. In this study, groundwater samples collected from the PCP site...

Aerobic granular sludge (AGS) comprises an aggregation of microbial cells in a tridimensional matrix, which is able to remove carbon, nitrogen and phosphorous as well other pollutants single bioreactor under the same operational conditions. During past decades, feasibility implementing AGS wastewater treatment plants (WWTPs) for treating sewage using fundamentally sequential batch reactors (SBR...

The moving bed biofilm reactor (MBBR) has proven to be an effective system for the treatment of municipal and industrial wastewater. main operating mechanism reactors is growth attached biomass in carriers bioreactor with mixing provided by diffusers aerobic bioreactors or mechanical stirrers anoxic/anaerobic bioreactors. Biofilm formation a complex process affected microbial composition proper...

Limited available water resources have rendered wastewater reuse an important issue to specialists in most developed countries, today. The current study works on membrane filtration for treatment of industrial wastewater. By comparing the two methods of membrane bioreactor (MBR) and hybrid membrane electro bioreactor (MEBR) processes, it finds that earlier fouling in the membrane occurs in the ...

Bacterial cellulose (BC) is an abundant polysaccharide, which secreted by several genera of bacteria. It has remarkable characteristics, include high purity, tensile strength, biocompatibility and non-toxic. The main feature that differentiates BC plant (PC) the absence contaminants such as lignin, hemicellulose pectin. However, drawbacks in producing are low yield expensive carbon source. Due ...
