2.9. Statistics
All reported experimental results (solid-state fermentation, enzyme assays and protein concentration) are calculated average measurements of repeated experimental runs (duplicates) with ±SD (standard deviation) less than 5% of the reported average. Six replications were performed per each isolate for statistical analysis of morpho-physiological studies. One-way analysis of variance among obtained data was tested by ANOVA, including comparison of means by F-test. The level of significance was at least P < 0.05 (Sokal and Rohlf, 1995). Statistical data analysis was performed
using Statistica software for Windows 6.0 (Stat Soft Italia 1997).
