Aspergillus niger dregs are by product with abundance of resources reserve after its industrial fermentation for required products processing. Currently, there are a great variety of preparations produced using A. niger, however, report on comprehensive utilization of the dregs yet it is still relatively few. The existing studies suggested that dregs of A. niger not only can be used directly as forage additive, organic fertilizer, or soil modifying agent, but also can be used in refinements as main materials for food, medicines, cosmetics, and other industries, to realize its application with high added-value conversion. Moreover, it can be used as bio adsorbent to remove pollutants in waters. Combined with the actual state of A. niger dregs utilization studies in various fields, this paper summarized the advances in the conversion of and the studies on the utilization of A. niger dregs with high added value, and could provide theoretical references for the utilization of industrial fermentation by making dregs as resources. |
