Bio-production of novel water-soluble yellow pigment from Aspergillus sp. and exploring its sustainable textile applications.

ABSTRACT: In the present study, 40 pigment-producing microbes were isolated from various soil sources. Among these, a novel water-soluble yellow pigment-producing fungal isolate (MBYP1) was identified as Aspergillus sp. through ITS gene sequencing. The maximum pigment yield (UA_430nm, 12.45 ± 0.5 g/l) was obtained when strain MBYP1 was cultured under optimum conditions (28 °C and pH 5.5 under static condition). Subsequently, the pigment was purified through gel chromatography and high-performance liquid chromatography (HPLC). Characterization of purified pigment through UV-Vis and liquid chromatography-mass spectrometry (LC-MS) reveal maximum absorbance at 430 nm and molecular mass of 301 m/z, respectively. Further, the pigment exhibited a maximum dyeing capacity of up
