Exploration of endophytic fungi from leaf (Syzygium polyanthum wight) and its potential probiotic for poultry

Abstract

The use of antibiotics may have a negative impact on animal health. There is an option use a probiotics that can improve intestinal health and performance. Fungi has a probiotic potential and one example is endophytic fungi that can produce various bioactive compounds which are needed to act as probiotic. The study aims to explore of endophytic fungi from Bay leaf  and to evaluate its potential probiotic for poultry. The materials used  leaves and petioles. The method was isolation, identification, assay of antifungal, antibacterial activity, acid and bile salt resistence The exploration got P.  Echinulatum, P. Solitum , P. paneum , O. griseum , F. verticillioides  and F. avenaceum. The highest number of colonies was O. griseum , the lowest of dominance to A. flavus was F. verticillioides, the widest of diameter of the inhibition zone to E. coli was F. verticillioides and  S. aureus was .P  echinulatum, the fastest growing on acidic media is F. avenaceum and  on bile salt is F. avenaceum. The conclusion was the exploration got P.  echinulatum, P.  solitum, P.  paneum, O. griseum F. avenaceum,  and F. verticillioides. and  P. echinulatum is  the most potential species as a probiotic for poultry.
