Recently, the demand for fungal pigments has increased due to their several benefits over synthetic dyes. Many species of fungi are known to produce pigments and a large number of fungal strains for pigment production are yet to be extensively investigated. The natural pigment from sustainable natural sources has good economic and industrial value. Many synthetic colorants used in textile and various industries have many harmful effects on the human population and environment. Pigments and coloring agents may be extracted from a wide range of fungal species. These compounds are among the natural compounds having the most significant promise for medicinal, culinary, cosmetics, and textile applications. This study attempts to isolate and optimize the fermentation conditions of Penicillium sclerotiorum strain AK-1 for pigment production. A dark yellow-colored pigment was isolated from the strain with significant extractive value and antioxidant capacity. This study also identifies that the pigment does not have any cytotoxic effect and is multicomponent. The pigment production was optimized for the parameters such as pH, temperature, carbon and nitrogen source. Fabric dyeing experiments showed significant dyeing capacity of the pigment on cotton fabrics. Accordingly, the natural dye isolated from P. sclerotiorum strain AK-1 has a high potential for industrial-scale dyeing of cotton materials.
近年来，由于真菌色素相较于合成染料具有多种优势，其需求量不断增加。已知许多真菌物种能够产生色素，然而大量用于色素生产的真菌菌株尚未得到广泛研究。来自可持续天然来源的天然色素具有良好的经济和工业价值。纺织业及其他行业中使用的许多合成色素对人类和环境都有诸多有害影响。色素和着色剂可从多种真菌物种中提取。这些化合物是在医药、烹饪、化妆品和纺织应用方面最具潜力的天然化合物之一。本研究旨在分离并优化核盘青霉AK-1菌株用于色素生产的发酵条件。从该菌株中分离出一种具有显著提取价值和抗氧化能力的深黄色色素。本研究还确定该色素无任何细胞毒性作用且为多组分。针对pH值、温度、碳源和氮源等参数对色素生产进行了优化。织物染色实验表明该色素对棉织物具有显著的染色能力。因此，从核盘青霉AK-1菌株中分离出的天然染料在棉织物的工业规模染色方面具有很高的潜力。
