Some Problems of Air-borne Micro-organisms in Cultivation of Collybia velutipes (Curt.) Fr. 1Air-borne Micro-organisms during the Winter
田部, 真
田端, 信一郎
The detrimental effect of various micro-organisms on the cultivated Collybia velutipes is a great problem in Nagano prefecture. Most of these micro-organisms are present in the air, and inhibit fruiting of C. velutipes after growing on the compost. 1. Air-borne micro-organisms isolated during the winter were 14 bacteria, 9 Streptomyces, 20 Penicillium and 6 other fungi on potato sucrose agar. 2. On these micro-organisms, morphological and physiological properties, effects on the growth of C. velutipes and epidemic considerations were investigated. 3. The micro-organisms tolerant to dry heat were 7 bacteria, 4 Streptomyces, 8 Penicillium and 2 other fungi. 4. The collected micro-organisms were generally tolerant to dry heat more than hot water, but 2 bacteria were torelant to hot water. 5. All isolates of fungi, 7 bacteria, and 2 Streptomyces were most tolerant to ultra-violet.
