Chemical decay of an antibiotic inverts selection for resistance [PDF]
Nature Chemical Biology, 2010 Antibiotics are often unstable and can decay into various compounds with potential biological activities. We found that as tetracycline degrades, the competitive advantage conferred to bacteria by resistance not only diminishes but actually reverses to become a prolonged disadvantage due to the activities of more stable degradation products ...

Decay-resistance of particleboard.
Wood Preservation, 1986 微小菌類を含む種々の菌類に対して,市販されているパーティクルボードの耐朽性を評価すべく実験を行った。また,ボードの曲げ強度に及ぼす菌類の影響も調べた。ボードの重量減少率は,菌の種類によって変動した。かっ色腐れ菌オオウズラタケは,メラミンユリア樹脂製ボードに大きな重量減少率を生じたが,フェノール樹脂製ボードを腐朽しなかった。一方,白腐れ菌カワラタケは場合によって,メラミンユリアボードよりもフェノールボードに,より大きな重量減少率を生じた。JWPA規格3号で評価した場合,一般にボードの耐朽性は高かった。ボードの曲げ強度は,腐朽の進行とともに急激に減少した。同一重量減少率では,メラミンユリアボードとフェノールボードの強度減少間に,差を認めることは出来ない ...

Resistance to Phomopsis Seed Decay in Soybean [PDF]
ISRN Agronomy, 2013 Phomopsis seed decay (PSD) of soybean is caused primarily by the fungal pathogen Phomopsis longicolla Hobbs along with other Phomopsis and Diaporthe spp. This disease causes poor seed quality and suppresses yield in most soybean-growing countries. Infected soybean seeds can be symptomless, but are typically shriveled, elongated, cracked, and have a ...

Decay Resistance of Weathered Beech Wood
Journal of Anatolian Environmental and Animal Sciences, 2020 Wood is susceptible to photo-degradation in outdoor applications, and deformations occur on its surface such as micro or macro cracks, color changes etc. Especially, cracks make wood material more vulnerable to biotic attacks. In this study, decay resistance of natural and accelerated weathered beech samples was investigated by a brown (Coniophora ...
