DEFINITION

Classification: 435/257.1

Algae, media therefor:

(under subclass 243) Subject matter wherein the microorganism propagated or treated is a unicellular algae, or the media useful for the propagation of unicellular algae, or a composition containing unicellular algae, or methods of preparing said compositions or media.

(1) Note. Edible compositions containing unicellular algae are excluded herefrom.

(2) Note. Multicellular algae are excluded herefrom. Algae are presumed to be multicellular in the absence of a clear showing to the contrary.

(3) Note. Unicellular algae in this subclass include both eukaryotic and prokaryotic algae. Examples of eukaryotes include Chlorophyta (green algae, such as Chlorella, Scenedesmus, etc.), Euglenophyta (Euglena), Rhodophyta (red algae), etc. Examples of prokaryotes include Cyanobacteria (blue-green algae, such as Anacystis, Anabaena, etc.).

(4) Note. microorganisms of the genera Euglena and Chlamydomonas are currently classified in both algal (Bold and Wynne) and protozoan (Levine) taxonomic systems due to their photosynthetic and motility systems. For classification purposes, these genera are placed under algae unless the reference specifically eludes to the "protozoan" nature of the microorganism.
