N. auteur aut IRD text journalArticle eng text/pdf born digital access Extra- and intracellular tannase production by Aspergillus niger GH1 has been evaluated using submerged (SmF) and solid-state fermentation (SSF) at different temperatures (30, 40 and 50 degrees C). Effects of initial substrate (tannic acid) concentration, incubation time and temperature on tannase production in SSF have been studied. A. niger GH1 produced the highest tannase level (2291 U/L) in SSF at 30 degrees C during the first 20 h of culture at tannic acid concentration of 50 g/L, and under these conditions enzyme production was entirely extracellular. The decline in tannase activity after 20 h of incubation was associated with a concomitant increase in protease activity. specialized tannase culture conditions solid state fermentation Aspergillus niger 084 44 4 541-544 2006 1330-9862 https://www.documentation.ird.fr/hor/fdi:010037745 1330-9862 [F A010037745] https://www.documentation.ird.fr/hor/fdi:010037745 https://www.documentation.ird.fr/intranet/publi/2007/01/010037745.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2007-01-29 2017-08-23 fdi:010037745 fre
