Abstract
Experiments were performed to quantitatively determine the destruction of spore-forming bacteria. A straightforward protocol was established to prepare and characterize various bacteria and analyze the samples after treatment by atmospheric-pressure plasma jets emanating from the plasma reactor using either in He or air (N2/O2 mixture) as a carrier gas at varying power levels and exposure times. Several Bacillus subtilis strains were used. Significant reductions in colony-forming units were found. The UV/VIS absorption spectrum of the pore suspension was also determined before and after several minutes of plasma treatment.
