Raw starch degrading enzymes (RSDE) refer to enzymes that can directly degrade raw starch granules below the gelatinization temperature of starch. These promising enzymes can significantly reduce energy and simplify the process in starch industry. RSDE are ubiquitous and produced by plants, animals, and microorganisms. However, microbial sources are the most preferred one for large-scale production. During the past few decades, RSDE have been studied extensively. This paper reviews the recent development in the production, purification, properties, and application of microbial RSDE. This is the first review on microbial RSDE to date.

Please cite this article as: Pothiraj C., Arun A., Eyini M. Simultaneous saccharification and fermentation of cassava waste for ethanol production. The efficiency of enzymatic and microbial saccharification of cassava waste for ethanol production was investigated and the effective parameters were optimized. The mixture of amylase and amyloglucosidase (AMG) resulted in a significantly higher rate of saccharification (79.6%) than the amylase alone (68.7%). Simultaneous saccharification and fermentation (SSF) yielded 6.2 g L -1 ethanol representing 64.5% of the theoretical yield. Saccharification and fermentation using pure and cocultures of fungal isolates including Rhizopus stolonifer, Aspergillus terreus, Saccharomyces diastaticus and Zymomonas mobilis revealed that the co-culture system involving S. diastaticus and Z. mobilis was highly suitable for the bio-conversion of cassava waste into ethanol, resulting in 20.4 g L -1 in 36 h (91.3% of the theoretical yield).

The effect of methyl glucoside sesqui-stearate (MGS) on the production of raw starch degrading enzyme (RSDE) by Aspergillus oryzae F-30 was studied in this paper. The activity of RSDE formed by Aspergillus oryzae F-30 was enhanced dramatically by the addition of MGS to the medium. As a result, with the addition of 1.5 g MGS in 1 L basal medium, RSDE activity and productivity were 107 U mL(-1) and 1.49 U mL(-1) h(-1), 4.3-fold and 7.1-fold greater than the values obtained in the basal medium, respectively. The effect of MGS on the synthesis of RSDE by Aspergillus oryzae F-30 was also studied on a molecular level. It was observed that the regulation of RSDE synthesis in Aspergillus oryzae F-30 occurs at both transcriptional and translational level and the enzyme synthesis was provoked by the addition of MGS at transcriptional level.
