Critical evaluation of a putative glucosamine excretion by Aspergillus niger CBS120.49 and Penicillium ochrochloron CBS123.824 under citric acid producing conditions.

ABSTRACT: As one of the most frequently occurring monomers in the biosphere, glucosamine is a valuable metabolite for several applications. Although microbial glucosamine production is still in its infancy, it offers the possibility to circumvent problems associated with traditional production by hydrolysis. Of particular interest is a study with Aspergillus niger, which reports for the first time high glucosamine excretion in the early phase of citric acid production. These results have relevance for both the commercial glucosamine production and deeper insight into the regulation of organic acid excretion in fungi. To investigate glucosamine excretion, we performed bioreactor batch cultivations with Penicillium ochrochloron CBS123.824 and A. niger CBS120.49 using cultivation conditions which are k
