		Aspergillus fumigatus is a major constituent of compost, and mould fungi have been important sources of drugs including penicillin and ciclosporin (for transplantation).
		Aspergillus fumigatus is the most common Aspergillus species to cause disease, and is almost unique in causing infection at both extremes of the bodys immune function.
		Aspergillus oryzae is widely used in traditional Japanese food fermentation which originated approximately 2,000 years ago in China, as well as for enzyme production by biotechnology companies, and the sales volume of industries with some relation to the fungus is believed to have reached 1% of the total Japanese GDP (approximately $50 billion per year).

	AFFINITY IMMOBILISATION OF b-GALACTOSIDASE FROM Aspergillus oryzae ON LECTIN-BASED ADSORBENTS
		Aspergillus oryzaeb-galactosidase (E.C. 3.2.1.23) is an extracellular glycoprotein, which catalyses the hydrolysis of b-galactosidic linkages such as those present in lactose to yield glucose and galactose.
		We were interested in the immobilisation of b-galactosidase from Aspergillus oryzae, due to its potential uses in lactose conversion and also, because of its reported high capacity for trans-galactosidation reactions, a property which can be utilised to synthesise rare and expensive carbohydrate derivatives.
		It is reported that the a-amylase from Aspergillus oryzae is a glycoprotein (13) so, it could be expected that part of the activity would be found in the eluted material.

	Aspergillus - Wikipedia, the free encyclopedia
		Aspergillus was first catalogued in 1729 by the Italian priest and biologist Pietro Antonio Micheli.
		Aspergillus species are highly aerobic and are found in almost all oxygen-rich environments, where they commonly grow as molds on the surface of a substrate, as a result of the high oxygen tension.
		Firstly, koji mold such as Aspergillus oryzae is used to convert the starch in the rice to sugars (saccharification), which are subsequently fermented by other microorganisms, such as yeast (Saccharomyces) and lactic acid bacteria.
