Abstract

The results of a laboratory experiment modeling the effect of kerosene contamination on the cellulolytic activity of microbiocenosis of the Albic Retisol (Kaluga oblast, Russia) and Arenosol (Kyzylorda oblast, Republic of Kazakhstan) humus horizons are described. Cellulolytic activity is assessed according to the rate of weight loss in linen cloth fragments during the incubation for 0–3, 3–7, and 7–13 months. The intensity of cellulolytic activity in the unpolluted Albic Retisol is higher as compared with the Arenosol, which is determined by low acidity and an elevated content of organic matter and nutrients. The soil pollution with kerosene to 10 g/kg causes a reversible change in cellulolytic activity of both Albic Retisol and Arenosol (Aridic). A high load of kerosene (≥25 g/kg) inhibits cellulolytic activity in both soils over 13 months of observation.

煤油污染对 Albic Retisols 和 Arenosols (Ardic) 纤维素分解活性的影响：实验室实验

摘要

描述了模拟煤油污染对 Albic Retisol（俄罗斯卡卢加州）和 Arenosol（Kyzylorda 州，哈萨克斯坦共和国）腐殖质层的微生物群落的纤维素分解活性影响的实验室实验结果。根据孵育 0-3、3-7 和 7-13 个月期间亚麻布碎片的重量损失率评估纤维素分解活性。未污染的 Albic Retisol 的纤维素分解活性强度高于 Arenosol，这是由低酸度和较高的有机质和营养物质含量决定的。煤油污染土壤达到 10 g/kg 会导致 Albic Retisol 和 Arenosol (Ardic) 的纤维素分解活性发生可逆变化。
