The alkalitolerant and xylanolytic bacterial strain (RMV1) isolated from red mud pond was identified as Paenibacillus montaniterrae based on both biochemical and 16S rDNA sequence analysis. The RMV1 bacterial isolate produced alkalistable and thermostable endoxylanase active over a broad range of pH (4.0-11.0) and temperature (20-100 °C), with optima at 50 °C and pH 9.0 with a T1/2 of 6.7 hours at 50 °C. This is the first report on the isolation of P. montaniterrae from bauxite residue with quite a high xylanase producing ability.
