The study characterizes the anamorphic Bjerkandera adusta strain CCBAS 930, including growth conditions, physiological properties, and enzymatic activities related to basic metabolism and specific properties coupled with the fungal secondary metabolism. It was established that the fungus grows in a wide pH range (3.5–7.5), up to 3% of salt concentration and a temperature of 5–30 °C. Media rich in natural organic components (potato, maize extracts, whey) are optimal for biomass propagation. Minimal media, containing mineral salts and glucose as well as static growth conditions, are required to obtain idiophasic mycelium, equivalent to the secondary metabolism of the fungus. Of the 7 complex C, N, and energy sources tested, the strain did not utilize only fibrous cellulose. Lipolytic activity reached the highest values of the enzymatic activities corresponding to those capabilities. The specific properties of strain B. adusta CCBAS 930 determined by the production of HRP-like peroxidase were related to the decolorization and biodegradation of anthraquinone derivative daunomycin. The decolorization of 30% of daunomycin effluents occurred most rapidly in iso-osmotic medium and non-enriched with nitrogen, containing 0.25% glucose, pH = 5.0–6.0, and 25–30 °C. In agitated cultures, the strain decolorized solutions of daunomycin by biosorption, which coincided with the inhibition of aerial mycelium production and HRP-like biosynthesis. Based on knowledge, potential and real possibilities of using the strain in bioremediation of colored industrial sewage were discussed.

Bjerkandera adusta CCBAS930 的生长条件、生理特性以及工业废水中抗癌药物道诺霉素生物降解的最佳参数选择。

该研究描述了变形Bjerkandera adusta菌株 CCBAS 930 的特征，包括生长条件、生理特性和与基本代谢相关的酶活性以及与真菌次生代谢相结合的特定特性。据证实，真菌在较宽的 pH 范围 (3.5–7.5)、盐浓度高达 3% 和 5–30 °C 的温度下生长。富含天然有机成分（马铃薯、玉米提取物、乳清）的培养基是生物质繁殖的最佳选择。需要含有矿物盐和葡萄糖的基本培养基以及静态生长条件来获得固有相菌丝体，相当于真菌的次生代谢。在测试的 7 种复合碳、氮和能源中，该菌株不仅仅利用纤维状纤维素。脂肪分解活性达到与这些能力相对应的酶活性的最高值。菌株B. adusta CCBAS 930通过产生HRP样过氧化物酶而确定的特定性质与蒽醌衍生物道诺霉素的脱色和生物降解有关。30% 的道诺霉素流出液的脱色在等渗介质和非富氮、含有 0.25% 葡萄糖、pH = 5.0–6.0 和 25–30 °C 的条件下发生得最快。在搅拌培养中，该菌株通过生物吸附使道诺霉素溶液脱色，这与气生菌丝体产生和 HRP 样生物合成的抑制相一致。基于知识，讨论了将该菌株用于有色工业污水生物修复的潜力和实际可能性。
