The results show that this strain was a typical acidophile with optimal growth pH being 2.0 for hypha and pH 3.0-4.0 for the spore germination. Peptone was the most suitable nitrogen source which helped produce xylanase induced by xylan during stationary phase. The resultant xylanase reacted best at 50℃-55℃ and pH 3.5, and had activities 70% after 60 min maintenance under optimum reaction conditions.

This nonmutagenic amino compound 4 (via the investigation into Salmonella/mammalian microsome assay) was also employed as diazo moiety coupling with acet-J-acid to form a diazo acid dye 5. The new dye 5 can color wool at 2% or silk at 3% o. w. f. into black one. The investigation of the uptake of 5 and its color appearance showed that it was assigned to an acid bluish black dye and its blackness was more excellent than that of Acid Black 10B.

Its high-capacity and strong-acid-resistance were proved. In the acid condition, the adsorption efficiency to acide green 6B and direct fast yellow RL reached above 90%. Through the adsorption rate curve on adsorption behavior of the three dyes, they were all according with pseudo-secondary adsorption rate curve. The rate constant of adsorption increased with increasing temperature. Through the adsorption isotherm of the three dyes, acide green 6B and direct fast yellow RL were according with Langmuir equation, while disperse blue 56 was according with Freundlich equation. The adsorption behavior was an endothermic process. Entropy was increasing during the adsorption. So raising temperature was in favor of adsorption.
