N2  - Bacteria, yeast and filamentous fungi were isolated from various sites within a paper mill. Bacillus alvei and Aerobacter
aerogenes were the most prevalent contaminating bacteria. Maximum slime was produced by A. aerogenes
(4.2 mg ml-1) at pH 6.5 and by B. alvei (7.2 mg ml-1) at pH 7.5 in white water. The optimum temperature was 408C for
maximum slime production by both organisms. In the presence of levanase, a 25% reduction in dosages of a biocide
(BioplusÒ) was observed. Killing of A. aerogenes, which was achieved in 8 h with 20 ppm BioplusÒ, could be obtained
in 6 h with the combined use of levanase and a lower concentration of BioplusÒ (15 ppm). With B. alvei almost
the same inhibitory effect (4.22-log decrease) was obtained at 20 ppm BioplusÒ, and in combination with a lower
concentration of BioplusÒ (15 ppm) and enzyme. The paper properties did not show any adverse effect after treatment
with levanase and BioplusÒ.
