Screening, cloning, enzymatic properties of a novel thermostable cellulase enzyme, and its potential application on water hyacinth utilization.Cellulose is the cheapest, natural, renewable organic substance that is used as a carbon source in various fields.  However, natural cellulase can be hardly used in industrial production on account of its low thermal stability and activity.  Enzymatic properties of Cel1029 were explored, including optimum temperature and pH, thermal and pH stability, and tolerance against organic solvents, metal ions, and salt solutions.
