In this study, extraction of tannic acid using microchannel was investigated. Affective parameters were optimized. Different solvents including buthanol, ethylacetate and n-hexane as organic phase, methanol, propanol, ethanol and water as aqueous phase investigated. Microchannels with different confluence angles and diameters were examined. Microchannels with different confluence angles and dia...

Gallic acid production in a batch bioreactor was evaluated using as catalytic material the mouldy polyurethane solids (MPS) obtained from a solid-state fermentation (SSF) bioprocess carried out for tannase production by Aspergillus niger GH1 on polyurethane foam powder (PUF) with 5 % (v/w) of tannic acid as inducer. Fungal biomass, tannic acid consumption and tannase production were kinetically...

Bergenia species are evergreen herb belonging to the family saxifragaceae. The rhizomes of these plants are used in the indigenous system of medicines. There are three species of Bergenia, namely B. ligulata, B. ciliata and B. stracheyi. The rhizome and other parts of B. ligulata is used in urinary bladder stone, antilithic activity diuretic activity, anti-bradykinin activity, antiviral activit...
