Laccases are multi-copper oxidases that widely distributed in plants and fungi. These enzymes catalyze oxidation of various compounds including phenolics and non-phenolics, and have been used in many industrial processes such as paper industry, biobleaching and bioremediation. A full length cDNA (1767 bp) encoding a putative laccase (Lac) from Rigidoporus vinctus was cloned by polymerase chain ...

Penyakit jamur akar putih (JAP) yang disebabkan oleh Rigidoporus microporus merupakan penyakit penting pada tanaman karet. Pengendalian JAP umumnya menggunakan fungisida sintetik berdampak buruk terhadap lingkungan dan berbiaya mahal. Salah satu cara pengendalian tular tanah lebih murah efisien adalah pemanfaatan mikroorganisme antagonis. Penelitian ini bertujuan untuk menguji antagonisme rizos...

Rigidoporus microporus is the main causal of white root disease (WRD) in rubber trees (Hevea brasiliensis). The present study investigates use rhamnolipid, a biosurfactant produced by Pseudomonas aeruginosa USM-AR2 against R. microporus. In vitro dose-responses towards rhamnolipid were determined on different isolates using poisoned food technique (PFT). Inhibition mycelial growth was found to ...

Research on fungal endophytes has expanded dramatically in recent years, but little is known about the diversity and ecological roles of endophytic basidiomycetes. Here we report the analysis of 310 basidiomycetous endophytes isolated from wild and planted populations of the rubber tree genus, Hevea. Species accumulation curves were nonasymptotic, as in the majority of endophyte surveys, indica...
