pearl starch and dried on a drum dryer the pearl starch was cooked in two batches having solids measuring 16 7 and 16 3 yielding an approximate pick up of 110 ton sheets for samples e h were tested again for the same physical properties as before all sheets for samples a h were manually sanded using a belt sander and 80 grit sand paper samples b d f and h were manually dipped in a bath of intace b350 anti michotic agent to yield an approximate pick up of 2 ton then each sheet for those samples was dried on a drum dryer samples from each condition a h were cut into 1 u2033 wide tape strips then they were adhered to 3 u2033 u00d7 3 u2033 squares of anti microbial gypsum board using joint compound and allowed to air dry prior to inoculation 3 samples from each condition a h were soaked in u00bd u2033 of sterile water for 1 hour each gypsum board square was placed upright on its edge so that the water comes u00bd u2033 up the side of the square that has the tape touching the edge as indicated in fig4 sample squares were placed on 150 u00d7 25 mm agar plates and inoculated with 0 38 ml of inoculum containing chaetomium globosum aspergillus terreus and aspergillus niger the inoculum was spread along the bottom half of the sample square as seen in fig5 allowing a portion of the tape to remain uninoculated there was also a set of additional tape samples a h that were not.
