Última Production of amylases by Aspergillus tamarii Rev. Microbiol. Moreira,Fabiana Guillen; Lima,Francieli Arrias de; Pedrinho,Sophia Renata Fazzano; Lenartovicz,Veridiana; Souza,Cristina Giatti Marques de; Peralta,Rosane Marina. A strain of Aspergillus tamarii, a filamentous fungus isolated from soil, was able to produce both <FONT FACE="Symbol">a</FONT>-amylase and glucoamylase activities in mineral media supplemented with 1% (w/v) starch or maltose as the carbon source. Static cultivation led to significantly higher yields than those obtained using shaking culture. The production of amylases was tolerant to a wide range of initial culture pH values (from 4 to 10) and temperature (from 25 to 42oC). Two amylases, one <FONT FACE="Symbol">a</FONT>-amylase and one glucoamylase, were separated by ion exchange chromatography. Both partially purified enzymes had optimal activities at pH values between 4.5 and 6.0 and were stable under acid conditions (pH...

The capability of the plant pathogenic fungus Myrothecium verrucaria to produce extracellular hydrolytic enzymes in submerged cultures was studied using several substrates. The fungus was able to produce different depolymerases and glycosidases, being xylanase, pectinase and protease the most important. Lipase was found in cultures developed in the presence of olive oil, while protease activity was detected in all cultures. Xylanase and pectinase were optimally active at pH 4.5-5.5, while protease was active in a large range of pH 3.5 to 11.0. All three enzymes were maximally active at 40ºC and they were stable for several hours at temperature up to 50ºC.
