3039 results about "Aspergillus niger" patented technology

Aspergillus niger is a fungus and one of the most common species of the genus Aspergillus. It causes a disease called "black mold" on certain fruits and vegetables such as grapes, apricots, onions, and peanuts, and is a common contaminant of food. It is ubiquitous in soil and is commonly reported from indoor environments, where its black colonies can be confused with those of Stachybotrys (species of which have also been called "black mold").

InactiveUS6255115B1FungiMicroorganism based processesHeterologousMastigomycotina
The invention relates to Agrobacterium mediated transformation of moulds comprising species of the fungal sub-divisions Ascomycotina, Basidiomycotina, Deuteromycotina, Mastigomycotina, and Zygomycotina.Examples demonstrate the transformation of Aspergillus awamori (both protoplasts and conidia), Aspergillus nidulans, Aspergillus niger, Colletotrichum gloeosporioides, Fusarium solani pisi, Neurospora crassa, Trichoderma reesei, Pleurotus ostreatus and Agaricus bisporus (all conidia), and Fusarium graminearum (both conidia and rehydrated freeze dried ATCC material).Especially for Aspergillus awamori the transformation frequency is much higher than with conventional mould transformation techniques.It has further been found that not only one expressable gene can be introduced into these moulds, but even multiple copies of such gene, which, moreover, can be targeted e.g. in the chromosomal pyrG locus, as exemplified for A. awamori. These multiple copies can be of a gene encoding a desired, homologous or heterologous, protein.
