Protein enrichment of treated and untreated leached beet cosette

Production of Rhodotorula glutinis: a yeast that secretes a-L-arabinofuranosidase

“…Rubio et al (2002) described that R. glutinis has a high invertase activity that would allow the use of media with a high sugar content such as beet molasses. On the other hand, beet cosette presents cellulose and hemicellulose content with only 3.7 g/L of reducing sugars (Illanes and Schaffeld, 1983). This fact could explain the low growth rate observed when the yeast is cultivated with beet cosette, since there would be little availability of easily assimilated carbon substrates when compared with the other two carbon sources assayed.…”

“…On the other hand, the effect shown by the beet cosette on the production of Abf by R. glutinis L-1816 is independent of its concentration in the culture media. Illanes and Schaffeld (1983) by a hydrolysis experiment of this substrate indicated that its chemical composition includes 58.5% (w/v) of crude fiber. In our case, a hydrolysis was not carried out prior to its incorporation into the culture media, however, part of these components may have passed into solution and it is therefore possible that some induce the production of Abf.…”

Raw Starch Degrading Amylase Production by Various Fungal Cultures Grown on Cassava Waste

“…Various amylolytic fungi have been used for the production of SCP and amylase from starchy materials in submerged agitated culture (Kallel-Mhiri, 1994; Soccol, 1994). Several workers, however, have turned their attention to biodegradation of starch using solid state fermentation because this method has been found to be the more appropriate system than submerged fermentation for protein enrichment and amylase production from starchy materials (Park and Rivera, 1982; Forgarty, 1983; Illanes, 1983; Saha and Zeikus, 1989; Pandey et al, 2001). …”
