Logam berat bersifat persisten dalam lingkungan dan diketahui mengubah biodiversitas, struktur dan fungsi ekosistem tanah. Remediasi tanah terkontaminasi logam menjadi penting, karena tanah sebagai media penghasil bahan pangan. Pendekatan konvensional untuk remediasi tempat yang terkontaminasi logam meliputi fisika dan kimia, namun aplikasi proses-proses ini terbatas karena kendala teknologi dan ekonomi. Oleh karena itu diperlukan metode remediasi yang murah, aman dan ramah lingkungan seperti bioremediasi. Penelitian ini bertujuan untuk mengetahui kemampuan rhizobakteri dalam membantu fitoekstraksi logam berat kromium pada tanaman jagung. Tahapan penelitian meliputi 1) uji toleransi bakteri terhadap Cr(VI), 2) uji reduksi Cr(VI), dan 3) uji serapan Cr(VI) pada tanaman jagung. Hasil penelitian menunjukkan bahwa Isolat 27 toleran terhadap toksisitas Cr(VI) pada konsentrasi 15 ppm. Isolat 27 mereduksi Cr(VI) secara sempurna dalam waktu 18 jam. Isolat 27 membantu fitoekstraksi logam kromium pada tanaman jagung sebesar 241 kali dibandingkan kontrol. Perlu penelitian lebih lanjut untuk mengetahui jenis asam yang berperan dalam mekanisme fitoekstraksi pada tanaman jagung. Isolat 27 dapat digunakan sebagai inokulan dalam fitoremediasi dan pemacu pertumbuhan tanaman.

Production of glucoamylase by R. oryzae has been conducted in erlenmeyer flasks using medium containing sago starch as carbon source and soybean meal as nitrogen source. It was known that 2 % of sago starch and 0.5 % of soybean meal in the medium is the best composition for the production of glucoamylase. At the present study, the optimal condition for maximal production of glucoamylase fermentation from R. oryzae was investigated using sago starch medium in the 2L and 4L scale. The results showed that the maximum production of glucoamylase at 600-1500 ml fermentation scale was reached at day-8 of incubation time. At this condition, the enzyme specific activity was 0.85 U/mg protein - 1.50 U/mg protein. Forglucoamylase production within 4000 ml fermentation scale, the maximum enzyme specific activity, 2.58 U/mg protein, was obtained at day-S of fermentation with 300 rpm agitation, while the maximum activity of 3.47 U/mg protein and 4.71 Ulmg protein were achieved at day-6 and day-5 of fermentation process with 500 rpm and 700 rpm agitation, respectively. At this maximum condition, the use of sago starch reached 94 - 98 %, and biomass production at the end of fermentation process was 4.80 - 7.90 g [dry weight)/L medium.
