Spent mushroom substrate (SMS) of P. ostreatus is the residual compost waste generated by the mushroom production industry. The main component of P. ostreatus cultivation is sawdust that high of lignocellulosic material. The presence of cellulose and lignin can be the carbon source of indigenous cellulolytic and lignolytic bacteria. The study was conducted to know the existence of indigenous cellulolytic and lignolytic bacteria and determine their activity or potential character. This research was conducted using the purposive sampling method and analyzed descriptively. The result showed the existance of cellulolytic bacteria (41–51×105 cfu/g) and lignolytic bacteria (60-80 × 105) in SMS. PD04S has a higher cellulolytic index and PYK2L has a higher lignolytic index.

Nypa fruticans is a very important mangrove plant especially for coastal communities. It can be used as an alternative medicine. The research was conducted in several steps, there is isolation and identification of endophytic fungi. Isolation of endophytic fungi includes medium preparation, plant sampling, isolation of endophytic fungi from some parts of N. fruticans organs. The identification stage includes purification, characterization, and identification of endophytic fungi. Endophytic isolation obtained 7 isolates are Fusarium, 3 isolates are Aspergillus, 2 isolates are Acremonium, 2 isolates are Colletotrichum, 2 isolates are Scopulariopsis, 2 isolates are Gliocladium, 1 isolate is Trichocladium, and 1 isolate is a Geotrichum.
