1These samples were tested to determine the major species of Bacillus. 2This sample was tested for Actinomycetes because of white mycelia type growth on wood truss. 3These samples were tested by RealTime Laboratories for the presence of bacteria species on samples tested for mycotoxins. 4CFU was not determined. TNTC: too numerous to count. 5Endotoxins were analyzed by ESML using LAL Kinetic Chromogenic Assay.
