Filamentous fungi colonizing rice straw were collected from 11 different sites in Korea and were identified based on characterization of their morphology and molecular properties. The fungi were divided into 25 species belonging to 16 genera, including 14 ascomycetes, one zygomycete, and one basidiomycete. Fungal cellulolytic and xylanolytic enzymes were assessed through a two-step process, wherein highly active cellulase-and/or hemicellulaseproducing fungi were selected in a first screening step followed by a second step to isolate the best enzymeproducer. Twenty-five fungal species were first screened for the production of total cellulase (TC), endo-β-1,4 glucanase (EG), and endo-β-1,4 xylanase (XYL) using solid-state fermentation with rice straw as substrate. From this screening, six species, namely, Aspergillus niger KUC5183, A. ochraceus KUC5204, A. versicolor KUC5201, Mucor circinelloides KUC6014, Trichoderma harzianum 1 KUC5182, and an unknown basidiomycete species, KUC8721, were selected. These six species were then incubated in liquid Mandels' media containing cellulose, glucose, rice straw, or xylan as the sole carbon source and the activities of six different enzymes were measured. Enzyme production was highly influenced by media conditions and in some cases significantly increased. Through this screening process, Trichoderma harzianum 1 KUC5182 was selected as the best enzyme producer. Rice straw and xylan were good carbon sources for the screening of cellulolytic and xylanolytic enzymes.

“…The isolates of pure fungal strains for DNA extraction were subcultured on PDA and Rose Bengal media and Sempere and Santamarina, 2010). As the most populous country in the world, China needs to increase rice yield by approximately 20% by 2030 (Dong et al, 2017;Paterson and Lima, 2010).…”

“…P. oxalicum is an effective biological control agent against other fungal species, such as Fusarium oxysporum (Cal et al, 2001(Cal et al, , 2010 and Verticillium dahliae (Larena et al, 2010;Sabuquillo et al, 2005Sabuquillo et al, , 2006). An analysis on the antagonistic effect of P. oxalicum on A. alternata in rice under different temperature and water activity found that P. oxalicum is a good biological control agent of rice fungi pathogens (Sempere and Santamarina, 2010). This antagonistic agent was also tested for strawberry, pea, and tomato fungal strains, and other crop pathogens with good results (Cal et al, 2001(Cal et al, , 2008Windels and Kommedahl, 1982).…”

Rice is a staple food for over half of the world’s population, and fungal spoilage in stored rice may occur when the moisture content and temperature are conducive. Aspergillus sp. and Penicillium sp. are the most harmful toxigenic species that produce harmful mycotoxins. Molds pose a potential threat to public health and cause a huge economic loss. Therefore, it is of great importance to find out how molds multiply in rice. This study focused on the isolation and identification of fungi presented in rice and their evolution in rice with different moisture contents stored for varying periods of time and under different temperatures. Mold community was detected every month using the culture-dependent and -independent method of polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE). Significant differences were detected by the traditional culture method under different storage conditions. For potato dextrose agar (PDA) media, high temperature and moisture were suitable for the dominant strains including Penicillium aurantiogriseum and Penicillium oxalicum. In particular, P. oxalicum competitively inhibited the other fungi. For Rose Bengal medium, no difference was observed under different storage conditions, and only typical strains such as Aspergillus candidus and Alternaria were detected. PCR-DGGE identified some uncultured strains such as Trichoderma sp. and Cladosporium sp., the dominant strains and the flora diversity such as Aspergillus restrictus and Eurotium athecium. These results indicated that storage conditions greatly shape fungal growth. This study provides a foundation for the evolution of fungal flora in rice during storage in China and may help in developing biological control methods to prevent mold contamination in rice.

“…Interestingly, during the isolation of A. welwitschiae from sisal stem tissues with symptoms of brown rot, we frequently observed the emergence of fungal colonies characteristic of Penicillium sp. As some Penicillium species are reported to have antagonistic activity against phytopathogens (Ethur et al, 2005;Ma, Chang, Zhao, & Zhou, 2008;Sempere & Santamarina, 2010;Stefano, Nicoletti, Milone, & Zambardino, 1999), we conjecture whether Penicillium sp. could be exploited as a biocontrol agent against A. welwitschiae.…”

Agave sisalana, known as sisal, yields the world’s main natural stiff fiber used to produce various industrial products. The Brazilian semiarid is the largest sisal producing region in the world; however, production is under threat by sisal bole rot disease, caused by Aspergillus welwitschiae. Since chemical control of this disease is questionable in drought-ridden areas with little investment in crop management and due to environmental and public health concerns, the search for a biocontrol agent against A. welwitschiae is warranted. In this work, we isolated and identificated Penicillium citrinum as an endophyte from sisal plants collected from the Brazilian semi-arid and investigated whether it could be a biocontrol agent against sisal bole rot. P. citrinum inhibited the mycelium growth of A. welwitschiae by 65.8% when inoculated 72 hours before the pathogen, in dual culture medium assays. We found that P. citrinum can reduce sisal bole rot disease up to 90% when inoculated in sisal plants 48 hours before pathogen inoculation. Altogether, our data suggest a potential role for P. citrinum in the control of sisal bole rot disease.
