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.
