چکیده

 Bacillus cereus (IHB B 379) has been isolated from the sediments of illegal gold mining area located in Danau Biru Singkawang, these bacteria have resistant properties by being able to grow on media containing HgCl2 with a concentration 500 ppm. This study aimed determine effect temperature and mercuric chloride (HgCl2) growth optimum 379). The used Completely Randomized Factorial Design (CRD) consisting two treatment factors. first factor was different three levels, namely 320C, 370C, 420C. second 0 ppm, 250 test delusional method number colonies calculated using Total Plate Count (TPC) method. results showed that seriously affected . best pattern occurred at 320C
