Abstract

Since button mushroom (Agaricus bisporus) cultivation is performed in closed environment, the understanding of indoor environment becomes essential for the quality and quantitative production of the greenhouse-grown mushroom. To generate information on indoor environmental factors affecting on fruiting body quality, we investigated temperature, humidity, and bacterial concentration and species in a greenhouse located in Buyeo, Chungnam Province. Temperature and humidity were recorded as $19.75{\pm}0.35^{\circ}C$ and $87{\pm}3.67%$, respectively. The total concentration of bacteria was measured as $3.84{\times}10^3CFU/M^3$. Advenella kashmirensis, Bacillus vietnamensism, B. licheniformis, Burkholderia sordidicola, Fictibacillus phosphorivorans, Lysobacter daejeonensis, Microbacterium esteraromaticum, Pseudomonas aeruginosa, P. protegens, P. gessardii, P. mosseli were identified from indoor air of the greenhouse.

양송이는 재배사라는 밀폐된 환경에서 재배되는 바 양질의 생산을 위해서는 재배사 내 환경에 대한 정보가 요구된다. 본 연구는 양송이 재배사내 실내환경에 대한 기초 정보를 얻고자 수행되었다. 재배사 내 온도와 습도는 $19.75{\pm}0.35^{\circ}C$, $87{\pm}3.67%$로 세균이 서식할 수 있는 환경조건이었으며, 부유세균의 농도는 $3.84{\times}10^3cfu/m^3$로서 환경부에서 고시한 실내공기질 오염유지 기준치인 $8.0{\times}10^2cfu/m^3$을 초과하는 수치였다. 분리된 부유세균은 Advenella kashmirensis, Bacillus vietnamensism, B. licheniformis, Burkholderia sordidicola, Fictibacillus phosphorivorans, Lysobacter daejeonensis, Microbacterium esteraromaticum, Pseudomonas aeruginosa, P. protegens, P. gessardii, P. mosseli 등 7속 11종으로 동정되었다.
