Abstract

Abstract The ability of Trichoderma strains isolated from lignite and of Earth surface-derived strains to attack (solubilise) lignite, peat and wood was compared using glutamate as a carbon source. The results showed that lignite-derived microorganisms solubilise lignite to similar extent as Trichoderma strains isolated from the Earth surface. Solubilisation processes involve the action of enzymes and alkaline pH. The solubilisation of lignite was accompanied by a small increase of conidia-bound laccase, whereas that of peat was accompanied by (secretion) activity of cellulase, laminarinase, laccase, and lignin-peroxidase-like enzyme. In addition, data were obtained which show that bacteria contained in the lignite are able of lignite solubilisation and utilisation.

丝状真菌对Záhorie煤矿低阶煤的降解
摘要以谷氨酸为碳源,比较了从褐煤中分离的木霉菌株和地表衍生菌株攻击(溶解)褐煤、泥炭和木材的能力。结果表明,褐煤来源的微生物溶解褐煤的程度与从地球表面分离的木霉菌株相似。溶解过程涉及酶和碱性pH的作用。褐煤的溶解伴随着与分生孢子结合的漆酶的少量增加,而泥炭的溶解则伴随着纤维素酶、昆布酶、漆酶和木质素过氧化物酶样酶的(分泌)活性。此外,获得的数据表明,褐煤中含有的细菌能够溶解和利用褐煤。
