Wood ear mushroom (Auricularia heimuer) is one of the most popular mushrooms in Korea. Bacteria in the air can act as contaminants of mushroom media, mushroom pathogens, and sources of food poisoning in the indoor environment of mushroom cultivation houses. Therefore, cultivation houses require proper management to maintain mushroom production, quality and hygiene. This study was conducted to evaluate the properties of airborne bacterial species isolated from wood ear mushroom cultivation. Nine species of indoor-airborne bacteria were tested against wood ear mushroom cultivars using confrontation assay on PDA. Among 9 species, Bacillus subtilis DUCC18238 showed the strongest inhibition effect on the mycelial growth of nine wood ear mushroom cultivars and the inhibition rate for 7 of them was more than 30%. In addition, B. subtilis DUCC18238 inhibited the mycelial growth of 11 out of 18 wild mushroom species, 7 out of 8 phytopathogenic fungi, and 5 out of 5 Trichoderma species, respectively. The results of this study show that the management of airborne bacteria in the indoor environment of wood ear mushroom cultivation houses is necessary.
