Milk proteolysis caused by Pseudomonas fluorescens is a serious problem in the dairy industries as a result of its ability to grow under refrigeration. The use of phages to control contaminants in food has been considered an alternative to traditional methods; therefore, a thorough understanding of such organisms is vital for their use. In this study, we show the complete genome sequence and an...

Abstract The aim of the study was to evaluate efficiency Lemna minor purify synthetic dairy wastewater (SDW) and real (RDW), both diluted undiluted. Results showed that significantly reduced electrical conductivity (EC); removal for EC 19.4% in RDW 9.8% SDW. Higher values were recorded (DRDW) (41%) (DSDW) (35.8%). Total suspended solids slightly (14%) SDW (13.5%), compared DSDW (25%) DRDW (29%)...

In this study, the single chamber microbial fuel cell (MFC) with annular configuration and spiral anode geometry is proposed for future large-scale applications. Dairy wastewater containing complex organic matter was used as substrate. Factors affecting power generation and internal resistance of this MFC such as substrate injection, electrode surface area, and substrate concentration were inve...

Drought events and the overexploitation of freshwater resources have led to the increased need to manage groundwater reserves. Aquifer storage and recovery (ASR), whereby artificial water is injected into aquifers for storage, is one of the proposed methods by which freshwater supplies can be increased. Microbial clogging following injection, however, is a major issue. Here, during laboratory s...

Concentrated dairy operations emit trace gases such as ammonia (NH), methane (CH), and nitrous oxide (NO) to the atmosphere. The implementation of air quality regulations in livestock-producing states increases the need for accurate on-farm determination of emission rates. Our objective was to determine the emission rates of NH, CH, and NO from the open-freestall and wastewater pond source area...

the effect of hydraulic retention time in a range from 1.0-5.5 days was evaluated in a laboratoryscaleanaerobic fixed bed reactor packed with a hybrid material composed of tire rubber and zeolite. underthese conditions, cod removal efficiencies varied from 28.3% to 82.1%, respectively. over the more than 6months of operation, no clogging was observed. the results obtained demonstrated that this...

As well known, eutrophication is one of the main problems encountered in surface water. This phenomenon is caused by the excess phosphate level in the effluent of wastewater treatment plant. Thus, to control of eutrophication, removal of phosphorus is required. The aim of this study was to determine the efficiency of electrocoagulation (EC) process to phosphorus removal from the synthetic waste...

Among the food industries, the dairy industry is considered to be the most polluting one because of the large volume of wastewater generated and its high organic load. In this study, an aerobic membrane bioreactor (MBR) was used for the treatment of wastewater from a large dairy industry and two hydraulic retention times (HRT), 6 and 8 hours, were evaluated. For both HRTs removal efficiencies o...

The effects of irrigation with dairy factory wastewater on soil properties were investigated at two sites that had received irrigation for > 60 years. Two adjoining paired sites that had never received DFE were also sampled as well as another seven fields from a wider area around the factory. In comparison with paired sites that had not received effluent, long-term wastewater irrigation resulte...
