Water extract from spent mushroom substrate (WESMS) of Pleurotus eryngii suppressed bacterial wilt disease of tomato caused by Ralstonia solanacearum by 70% without any direct antibacterial activity against the pathogen. WESMS-treated tomato had increased contents of free phenolic compounds (increased by 3%) and total salicylic acid (increased by 75%), and significantly enhanced plant height, leaf number, and fresh weight compared to those of a water-treated tomato sample. These results suggest that the treatment of tomato with WESMS can suppress bacterial wilt disease by enhancing plant defense factors and overall plant health.

Water extract from spent mushroom substrates (SMS) of Pleurotus eryngii was utilized in decolorization of eight synthetic dyes and wastewater from a textile factory. High laccase activity was detected in the extract of P. eryngii (SMSE). The SMSE showed that decolorization rate was 34~93% after 24 h incubation without any mediator on eight dyes including Rit-blue and Rit-red used in fiber dyeing. Dye decolorization rate more than 90% was observed on bromophenol blue and remazol brilliant blue R (RBBR). Dye in textile wastewater was decolorized at room temperature after three days by addition of P. eryngii SMSE. The results suggest that biological decolorization of dyes using the P. eryngii SMSE can be used as environmental friendly materials.

Twelve Universal fungal PCR fingerprint (UFPF) primers that were modified from Universal rice primer (URP) were used to assess genetic diversity of 64 Agaricus strains including 45 A. bisporus strains and other 19 strains of other Agaricus spp. Eight primers, UFPF1, UFPF2, UFPF3, UFPF7, UFPF9, UFPF10, UFPF11, and UFPF12 produced PCR polymorphic bands within and between the Agaricus species. Primer UFPF7 produced specific PCR polymorphic bands that are distinct Korean strain from different strains. Ninety five PCR polymorphic bands were inputted for UPGMA cluster analysis. Forty five strains of A. bisporusare genetically clustered into 8 groups, showing coefficient similarity from 0.75 to 0.9 among them. The varieties, Saea, Saedo, Saejeong and Saeyeon that have recently been developed in Korea were involved in the same group with close genetic relationship of coefficient similarity over 0.96, whereas, other Korean strains were genetically related to A. bisporus strains that were introduced from USA, Eroupe and Chinese.
