Efeito da radiaçõa solar no tratamento de biofertilizante suíno, proveniente de biodigestor anaeróbio modelo indiano

Abstract

This work studied the effect of solar radiation in bacteria and endoparasites present in swine biofertilizer using the Ultraviolet Radiation Treatment Systems. To evaluate the efficiency of the system in the removal of pathogenic microorganisms, it was used the Most Probable Number Method (MPN / ml) and Agar Mac Conckey to check the existence of E-coli through the confirmatory test using tubes containing the Rugai environment culture modified with lysine. The method of sedimentation and Sedgewick counting chamber was used to set the number of eggs per gram of feces for detection of helminth eggs and protozoan oocysts. The results show that there was an efficient inactivation of E-coli after the end of the experiment. The same cannot be observed in relation to eggs of Ascaris sp eggs and Trichostrongylideos, oocyst of protozoa.
