Thermophilic Microorganisms in Biofilms from Greenhouse-Enclosed drip Irrigation Systems

Drip irrigation optimises water reuse and more efficient irrigation, but the system often presents problems of obstruction caused by the accumulation of biological material, starting with bacterial biofilms. The study of a drip system has detected prevalence of microorganisms adapted to growing in environments with high temperatures.
