Sažetak
The effect of zeolite on microorganism of pig excreta under aerobic and anaerobic laboratory conditions. Microorganism counts after 24 hours after adding 1 and 2 percent zeolite at anaerobic storing ranged within 3.8.10^6-3.7.10^9. In the control sample at anaerobic storing microorganism counts ranged within 9.9.10^6 – 3.8.10^9. At aerobic storing after adding 1 and 2 percent zeolite microorganism counts ranged within 3.7.10^6 – 4.8.10^9. The control at aerobic storing ranged within 6.5.10^6 – 7.9.10^9. The largest decrease in microorganism count was observed after 3 weeks in fecal coliform microorganisms. From week 6 onwards, no coliform or fecal coliform microorganisms were seen either at aerobic or aerobic storing. The largest decrease in mesophilic and psyhrophilic microorganisms occurred after 3 months from the beginning of the study. Numbers of mesophilic and psychrophilic microorganisms ranged at anaerobic storing within 3.2.10^6 – 8.0.10^6 and in the control within 3.5.10^7 – 3.3.10^7. Microorganism counts at aerobic storing ranged within 3.3.10^6 – 9.0.10^6 and in the control within 4.3.10^7 – 8.8.10^7.
