Being a non-renewable resource and a source of potential water pollution, phosphorus could be recovered from animal manure in the form of struvite (MgNH4PO4.6H2O) to be used as a slow-release fertilizer. It was found recently that the majority of phosphorus in anaerobically digested dairy effluent is tied up in a fine suspended calcium-phosphate solid, thus becoming unavailable for struvite for...

A purple non-sulfur bacterium isolated from dairy effluent was identified as Rps. palustris JA1. This organism was able to grow on pyridine as sole source of carbon in a light dependent anaerobic process with a doubling time of 30 h. Intermediates of pyridine photobiodegradation were identified as glycine and malonate, produced in stoichiometric molar ratios with simultaneous utilization, yield...

We report the 1.8-Mb genome sequence of Pediococcus pentosaceus strain IE-3, isolated from a dairy effluent sample. The whole-genome sequence of this strain will aid in comparative genomics of Pediococcus pentosaceus strains of diverse ecological origins and their biotechnological applications.

BACKGROUND Dairy effluents contains high organic load and unscrupulous discharge of these effluents into aquatic bodies is a matter of serious concern besides deteriorating their water quality. Whilst physico-chemical treatment is the common mode of treatment, immobilized microalgae can be potentially employed to treat high organic content which offer numerous benefits along with waste water tr...

The electrochemical oxidation of the digested effluent from anaerobic digestion of dairy manure was investigated in this study. The digested effluent sample containing with suspended solids was pretreated by filtration for the electrochemical experiment. The influence of direct anodic oxidation and indirect oxidation was evaluated through the use of dimensionally stable anode (DSA) and Ti/PbO2 ...

Over the past decade, there has been a rapid increase in dairy farming in New Zealand. Nitrate leaching from intensive agricultural systems, e.g. dairy farms, is suspected to cause increased nitrate concentrations in ground and surface waters. The objective of this research programme was to determine nitrate leaching losses on dairy pasture systems as affected by the application of dairy shed e...

Dairy waste, more than any other trade waste has long since attracted the attention of specialists in the field of waste water purification. Many experiments have been made with artificial waste water, made from milk or milk products. Dairy wastes provide an excellent nutrient medium for many types of bacteria and fungi and, contrary to opinions held at one time, are very amenable to aerobic bi...

Dairy wastewater management is a major concern for many milk-producing countries as it serious nuisance to the surroundings when disposed of untreated, increasing organic load and foul smell. Microalgae remediation an easy cost-effective treatment treat effluent simultaneously enhance few agronomic traits. In this research, phytoremediation technique was validated by treating dairy using microa...

The environmental loading of steroid hormones contained in dairy wastes may cause an adverse effect on aquatic species. To better assess the potential risks of hormone contamination resulting from land application of dairy wastes, various steroid hormones were determined in a typical dairy waste disposalsystem.Quantitativemethodsusinggaschromatography/ mass spectrometry (GC/MS) were developed t...

Background: Wastewater produced by a dairy in Sanandaj is a major source of environmental pollution threatening the city. The dairy uses activated sludge treatment to remove organic pollution from the wastewater. The present study evaluated the performance of this process and its compliance with national requirements for chemical oxygen demand (COD), biochemical oxygen demand (BOD), and total s...
