摘要

本研究的目的是了解西加里曼丹Sekadau区Belitang Hilir街道Simpi村非法采金(PETI)活动中汞金属降解细菌的存在。样本取自一个地点,有三个不同的采样点。NA-HgCl培养基中淋平板法分离细菌。在汞浓度为10 mg/L、20 mg/L和30 mg/L的情况下,基于穆勒-辛顿琼脂(MHA)抑制区抗性的纸盘法检测细菌。结果表明,一株纯分离株(PP)对10 mg/L汞胁迫的抗性最强

DETEKSI KEBERADAAN BAKTERI RESISTEN LOGAM MERKURI (Hg) PADA PENAMBANGAN EMAS TANPA IZIN (PETI) DI SIMPI, SEKADAU, KALIMANTAN BARAT
The purpose of this research is to know the existence of mercury metal degradation bacteria in the activity of illegal gold mining (PETI) in Simpi Village, Belitang Hilir sub-district, Sekadau District, West Kalimantan. The samples were taken from one location with three different sampling points. Isolation of bacteria by pour plate method  in NA-HgCl medium. Detection of bacteria by paper disc method based on inhibit zone resistant of  Mueller-Hinton Agar (MHA) with mercury levels such as 10 mg/L, 20 mg/L and 30 mg/L . The results showed that it was found that one pure isolate (PP) showed the most resistant isolate to the mercury stress of 10 mg/L can be detected
