Description
Fructooligosaccharides (FOS) are a type of oligosaccharides beneficial to gut health. In this PhD study, a simple FOS enzyme production process was developed with the use of a newly selected Aureobasidium pullulans strain as the enzyme producer and low-cost molasses as a carbon source. Furthermore, molasses-derived FOS were produced with the use of the A. pullulan cells as whole-cell biocatalysts and an invertase-deficient yeast for non-FOS sugars removal. The findings from this PhD study are important for further development and scale-up of the FOS production process towards commercialisation, which will benefit both Australian sugarcane and livestock industries.
Impact and interest:
Citation counts are sourced monthly from Scopus and Web of Science® citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads:
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
