Pengaruh Pemaparan Medan Magnet Pada Media Mandels Yang Dimodifikasi Terhadap Pertumbuhan Dan Aktivitas Enzim Selulase Bacillus Sp.
ABSTRACT: Enzymes can undergo structural changes due to various environmental factor such as pH, temperature, electricity and magnetic fields. The purpose of this study was to investigate the effect of magnetic field strength and duration of exposure to the modified of media Mandels used as a culture medium of Bacillus sp. on the growth and activity of cellulase enzyme from the bacterium Bacillus sp. Factorial study group were prepared using the method of full randomized design (RKLT). The first factor is the strong magnetic field consists of 4 levels of magnetic field strength treatment: 0 mT; 0,1 mT; 0,2 mT; 0.3 mT. The second faktor is the prolonged exposure consisting of 4 levels prolonged exposure treatments 0, 10, 20, 30 minutes. each unit treatment was repeated 3 times. The results showed that exposure to magnetic fields on modified of media Mandels causes a decrease in the relative activity of the enzyme cellulase and relative growth of Bacillus sp.
