Abstract

U današnje vrijeme svijet se suočava s problemom različitog onečišćenja okoliša. Ljudske aktivnosti povećale su pritisak na prirodne resurse i postale izvor brojnih onečišćujućih tvari. Primjena bioloških procesa za obradu otpadnih voda kategorizira se kao zelena tehnologija zbog iskorištavanja potencijala mikrobioloških konzorcija. Mikroorganizmi su ključno rješenje za prevladavanje izazova jer zbog svoje iznimne metaboličke aktivnosti opstaju na svim područjima u biosferi. Bioremedijacija je... More biološki mehanizam obnavljanja onečišćenog okoliša te je uključena u razgradnju različitih onečišćujućih tvari iz okoline kroz sveobuhvatno djelovanje mikroorganizma. U ovom radu istraženo je poboljšanje bioremedijacije procjedne vode dobivene iz biootpada biostimulacijom te bioaugmentacijom procjedne vode pomoću egzogenih kultura termofilnih mikroorganizama u šaržnim uvjetima. Fizikalno-kemijskim i mikroskopskim analizama dobiven je uvid u tijek procesa biorazgradnje prisutnih organskih onečišćujućih tvari. Vrijednost pH kretala se u optimalnom području za rast bakterijskih kultura te je iznosila 7,2±1,5. Svjetlosnom mikroskopijom dobiven je brzi uvid u promjene sustava tijekom procesa bioremedijacije. Učinkovitost poboljšanja bioremedijacije procjedne vode iz biootpada iznosila je 91 %. Less

Abstract (english)

Nowadays, the world is facing the problem of various environmental pollutions. Human activities have increased the pressure on natural resources and have become the source of numerous pollutants. The application of biological processes for wastewater treatment is classified as a green technology due to the use of the potential of microbiological consortia. Microorganisms are an important solution for addressing the challenges, as they are found in all areas of the biosphere due to their... More exceptional metabolic activity. Bioremediation is a biological mechanism to restore the polluted environment and deals with the degradation of various pollutants from the environment through the comprehensive action of microorganisms. This work investigated the improvement of bioremediation of leachate from biowaste by biostimulation and bioaugmentation of leachate with exogenous cultures of the thermophilic microorganisms under batch conditions. Physico-chemical and microscopic analyses provided insight into the course of the biodegradation process of the organic pollutants present. The pH value of 7.2±1.5 was in the optimal range for the bacterial growth. Light microscopy allows a quicker insight into the system changes during bioremediation process. The efficiency of the bioremediation improvement of biowaste leachate was 91%. Less
