Slaughterhouse wastewater contains various and high amounts of organic matter (e.g., proteins, blood, fat and lard). In order to produce an effluent suitable for stream discharge, chemical coagulation and electrocoagulation techniques have been particularly explored at the laboratory pilot scale for organic compounds removal from slaughterhouse effluent. The purpose of this work was to investig...

Pacidamycins are a family of uridyl tetra/pentapeptide antibiotics that act on the translocase MraY to block bacterial cell wall assembly. To elucidate the biosynthetic logic of pacidamcyins, a putative gene cluster was identified by 454 shotgun genome sequencing of the producer Streptomyces coeruleorubidus NRRL 18370. The 31-kb gene cluster encodes 22 proteins (PacA-V), including highly dissoc...

Membrane filtration is one of the alternatives suggested for the future drinking water production. Worldwide, the total number of ceramic membrane usage for water treatment is increasing swiftly and this is the first ceramic filtration study which is applied to a surface water treatment in a tropical region. This study was conducted to investigate the removals of natural organic matter and path...

The aim of this work was the study of the combination of an inorganic pre-polymerized coagulant (PACl) with ferric species and polysilicic acid in various mixing order, Al/Fe/Si and OH/Al molar ratios, and two polymerization techniques for the production of a unique reagent representing a coagulant, more efficient than commercial PACl-18 and laboratory prepared PACllab for water or wastewater t...
