The results (Table 1) indicated that proliferations of B. subtilis, thermophilic bacilli, A. niger, and A. oryzae were hypersensitive to TLS and TLS formulation. The inhibition zones were large (d > 10 mm). S. cerevisiae and osmophilic yeast were relatively insensitive to TLS and TLS formulation (inhibition zones diameters were between 1 mm and 10 mm).
