78 results about "Pseudoalteromonas" patented technology

Pseudoalteromonas is a genus of marine bacteria. In 1995, Gauthier et al proposed Pseudoalteromonas as a new genus to be split from Alteromonas. The Pseudoalteromonas species that were described before 1995 were originally part of the genus Alteromonas, and were reassigned to Pseudoalteromonas based on their rRNA-DNA analysis.
