TL;DR: Water and salt extraction of a coagulant protein from the seed, purification using ion exchange, its chemical characteristics, coagulation and antimicrobial properties, and assay of MO coagulating proteins are presented.

TL;DR: Two new assays studying ammonia oxidation and nitrite oxidation, respectively, are presented, applicable to determination of nitrification inhibition in samples of industrial waste waters or influents of treatment plants, or chemical substances likely to be found in wastewater.

TL;DR: Biodegradation of polycyclic aromatic hydrocarbons at low temperature and under anaerobic conditions is not wellunderstood, but such biodegradation would be very useful formediation of polluted sites and Ribosomal intergenic spacer analysis suggested that enrichment resulted in few predominant bacterial populations.

TL;DR: Papyrus root structures provided more microbial attachment sites, sufficient wastewater residence time, trapping and settlement of suspended particles, surface area for pollutant adsorption, uptake, assimilation in plant tissues and oxygen for organic and inorganic matter oxidation in the rhizosphere, accounting for its high treatment efficiency.

TL;DR: To find a biomarker for denitrification in activated sludge, five denitrifying strains isolated from three wastewater treatment plants were studied and phylogenetic analysis revealed that these strains are positioned among members of the genus Comamonas in the beta-subclass of the Proteobacteria.
