Zusammenfassung:	Schizophyllan is a biopolymer used as a skin care product and immunity enhancement agent. This short communication studies the rheology of schizophyllan solution under high salinity and high temperature. Experiments show schizophyllan maintains high viscosity under very high salinity. The loss of viscosity is insignificant under high temperature up to 100 °C. The impressive stability of schizophyllan under high temperature and high salinity renders its potential to enhance oil recovery in oil and gas industry. A field pilot was carried out since 2012. Field results indicate the injection of schizophyllan solution into oil strata leads to improved oil production.
