In the present study, a siderophore compound produced by an endophytic fungus, Talaromyces trachyspermus was optimized for maximum production, 88.9 % SU by applying Plackett-Burman design and Response Surface Methodology through Central Composite Design that showed the succinic acid (1.141 g/L), sucrose (31.028 g/L) and temperature (27.475 {degrees}C) as significant factors. On scale up, a further increase in siderophore yield was obtained (by 3%) The compound was extracted, purified and detected chemically as catecholate siderophore showing max. {lambda} absorbance at 279nm. Contained of hydroxy benzene as shown by GC-MS analysis and further identified as berberine by HRLC-MS studies. The compound berberine is clinically a very important drug with several ethnobotanical properties. This is rare to report fungal catecholate and first to report the production of berberine from Talaromyces species.
