A division of predominantly marine EUKARYOTA, commonly known as brown algae, having CHROMATOPHORES containing carotenoid PIGMENTS, BIOLOGICAL. ALGINATES and phlorotannins occur widely in all major orders. They are considered the most highly evolved algae because of their well-developed multicellular organization and structural complexity.
Deoxyribonucleic acid that makes up the genetic material of algae.
An enzyme that catalyzes the conversion of ATP, L-glutamate, and NH3 to ADP, orthophosphate, and L-glutamine. It also acts more slowly on 4-methylene-L-glutamate. (From Enzyme Nomenclature, 1992) EC
A genus of protozoa of the suborder BLASTOCYSTINA. It was first classified as a yeast but further studies have shown it to be a protozoan.
Nonparasitic free-living flatworms of the class Turbellaria. The most common genera are Dugesia, formerly Planaria, which lives in water, and Bipalium, which lives on land. Geoplana occurs in South America and California.
A genus of green algae found in the Mediterranean and other warm seas.
A genus of gram-negative, aerobic bacteria in the family OCEANOSPIRILLACEAE. Members of this genus have the ability to synthesize MELANIN pigments.

The myrtle plant family of the order Myrtales. It includes several aromatic medicinal plants such as EUCALYPTUS.
A combustible, gaseous mixture of low-molecular weight PARAFFIN hydrocarbons, generated below the surface of the earth. It contains mostly METHANE and ETHANE with small amounts of PROPANE; BUTANES; and higher hydrocarbons, and sometimes NITROGEN; CARBON DIOXIDE; HYDROGEN SULFIDE; and HELIUM.
