his research aimed at screening of phytase-producing bacteria previously isolatedfrom the gastrointestinal tract of poultry as probiotic candidates. Two screening indicators wereused; (1) the capacity to produce phytase, and (2) the ability to grow in sugar media. Thisresearch was conducted at laboratory of Microbiology and Biotechnology, Faculty of AnimalScience, University of Mataram for about 4 months since January to April 2019. Initially,bacteria were subculture in LB broth and on agar through serial dilutions to get a pure colony.Thereafter, the pure isolates were grown on sodium phytate-containing agar . The results showsthat 4 bacteria had a capacity to produce phytase indicated by the formation of clearance zoneon the sodium phytate-containing agar ; three of them appeared to be member of lactic acidbacteria (LAB) indicated by their ability to ferment glucose. Since LAB members are generallyregarded as safe (GRAS) microorganism, the results may suggest that the three bacterialisolates are potential probiont for poultry, although in vivo study using live poultry should befurther investigated to get more comprehensive result
