''
Lyngbya''. It is named after the
Dane Hans Christian Lyngbye.
As a result of recent genetic analyses, several new genera were erected from the genus ''Lyngbya'': ''e.g.'', ''
Moorea'',
''
Limnoraphis'',
''
Okeania'',
''
Microseira'',
and ''
Dapis''.
Several specimens identified as ''L. majuscula'' and collected in marine tropical regions are now classified as members of the genera ''Okeania'' and ''Moorea''.
''L. majuscula'' is the cause of seaweed dermatitis.
Chemical constituents
Almost 300 different secondary metabolites have been isolated from specimens identified as ''L. majuscula''. However, most of these studies lack a molecular identification of the samples. The toxins

kalkitoxin and the
lipopeptide
A lipopeptide is a molecule consisting of a lipid connected to a peptide. They are able to self-assemble into different structures. Many bacteria produce these molecules as a part of their metabolism, especially those of the genus ''Bacillus'', ...
