戶外貯存製漿木片感染微生物之研究

製漿木片多堆積於戶外，易滋生微生物，而發生劣化，造成經濟上之損失，本研究以銀合歡去皮及含皮木片為試材，於實驗室內以絕緣箱模擬戶外堆積180天。然後分離培養，以Nobles檢索表，鑑定木片上之微生物種類，並與戶外堆積75天的商用銀合歡含皮木片對照。常見的菌類按出現頻率依次為：曲黴菌屬(Aspergillus)鏈刀菌屬(Fusarium)，白腐菌(White rot)，木黴菌屬(Trichoderma)、青黴菌屬(Penicillium)等。

Pulpwood chips stored outdoor were subject to microbial attack, which can cause significant pulp quality deterioration and economic losses. This study was a microbial analysis of Leucaena barked and debarked wood chips stored under simulated laboratory conditions for 180 days and commercial wood chips stored in yard for 75 days. Subsequently the colonizing fungi on the wood chips were isolated and identified according to Noblest' Key. In this experiments, white rot fungi and mold fungi such as Aspergillus, Fusarium, White rot, Trichoderma, and Penicillium in decreasing order of frequencies were found t be the dominant species on the wood chips.
