“…The different growth rates indicated that the bacteria in older mines had better adaptability to greater pollutant loads (i.e., higher mercury concentration). When bacteria can grow to certain population size, they are considered adaptive and resistant to polluted land, which means that their surface protein production can successfully bind heavy metals (Hardiani et al, 2011). In this research, large pollutant loads tended to delay the bacterial growth (i.e., started on Day 7) because bacteria needed time to adapt to the highly contaminated environment and, at the same time, prepared themselves for growth.…”

Potential of Soil Bacteria as Mercury Bioremediation Agent in Traditional Gold Mining

Mandor Village has developed as a tradisional gold mining area since years ago. It involved activities that have led to extreme land condition and the release of mining residues, i.e., mercury, to the soils. The study examined the potential of soil bacteria as mercury bioremediation agent based on their population and activity in former mines with different ages. The bacterial population was measured by isolating soil bacteria on solid media using the pour plate method, and the colonies were enumerated during the incubation. The Nutrient Agar (NA) medium was used to obtain the total population, whereas the Salt Base Solution (SBS) was to determine the presence of mercury-tolerant bacteria. The addition of HgCl 2 affected the number of the colonies. The colony only grew until the concentration of HgCl 2 reached 5 mg/l, and the total colony was larger in older mines. The observation of bacterial activity showed that biotransformation performance was lower when the concentration of mercury was the same as its natural presence in soils (0.1-0.5 mg/l) compared with higher mercury level (1 mg/l). The research showed that lower mercury concentrations in nature reduced the natural ability of bacteria to transform pollutants. This study provides information that can assist the development of a technological approach to control mercury pollution in former traditional gold mines in an environmentally friendly manner using indigenous soil bacteria.

AbstrakTumbuhan akutik dikenal masyarakat sebagai tanaman hias dalam kolam/taman air karena bentuk, warna daun ataupun bunga yang indah. Selain bernilai estetik, tumbuhan akuatik memiliki nilai ekologi yang tinggi, salah satunya dalam fitoteknologi. Fitoteknologi dapat diterapkan dalam fitoproteksi, fitoremediasi, fitomonitoring maupun fitoforensik pencemaran lingkungan. Pencemaran lingkungan oleh logam berat dapat menganggu ekosistem dan membahayakan kesehatan manusia, bila terserap dan terakumulasi dalam tubuh, bahkan berakibat kematian. Logam berat toksik dan merupakan pencemar di semua media lingkungan, adalah Pb

“…Hasil analisis logam berat dari tanah terkontaminasi menunjukkan tanah mengandung Pb 61,8% lebih tinggi daripada sludge yaitu sebesar 63,1 mg/kg (Hardiani, 2011). Meningkatnya kandungan logam pada tanah terkontaminasi menunjukkan bahwa logam telah terkonsentrasi dalam tanah karena sudah terkontaminasi cukup lama (3-5 tahun), akibatnya senyawa organik yang ada telah termineralisasi sehingga kandungan logam berat pada tanah meningkat.…”

Lead contaminated soil bioremediation using microbial consortium has been conducted on laboratorioum scale. Four types of lead accumulating bacteria, PG 65-06 (A): PG 97-02 (B): MR 1.12-05 (C) and A1 (D) with a ratio of ABSTRAKBioremediasi tanah yang terkontaminasi timbal (Pb) menggunakan konsorsium mikroba telah dilakukan pada skala laboratorium. Empat jenis bakteri pengakumulasi Pb, PG 65-06 (A): PG 97-02 (B): MR 1.12-05 (C) dan A1 (D) dengan perbandingan 1:1:1:1 digunakan sebagai konsorsium mikroba. Penelitian dilakukan selama 60 hari dengan variasi penambahan inokulum mikroba 5%, 10%, 15% (v/w) dan penambahan inokulum 5%+ jerami padi sebagai bulking agents. Pengamatan dilakukan setiap 10 hari sekali dengan parameter konsentrasi logam Pb, aktivitas mikroba tanah, serta analisis sifat fisika-kimia tanah pada awal dan akhir proses bioremediasi. Penambahan konsorsium mikroba dapat mempercepat proses remediasi logam Pb pada tanah terkontaminasi dibandingkan dengan konsorsium mikroba 5%+jerami, yang ditandai dengan menurunnya konsentrasi logam Pb dari fase tertukarkan menjadi fase residual. Perubahan fase tersebut optimal pada waktu inkubasi 40 hari pada penambahan inokulum 10% (v/w) dan pada waktu inkubasi 50 hari pada penambahan mikroba 5%+jerami. Penambahan jerami meningkatkan aktivitas mikroba indigenous yang ditunjukkan dengan meningkatnya jumlah mikroba tanah dan produksi CO 2 yang dihasilkan dibandingkan penambahan inokulum mikroba. Karakteristik tanah terkontaminasi yang telah diremediasi oleh konsorsium mikroba menjadi lebih baik karena kandungan unsur hara tanah baik makro maupun mikro meningkat dibandingkan sebelum diremediasi.
