Biliopancreatic Diversion: A surgical procedure which diverts pancreatobiliary secretions via the duodenum and the jejunum into the colon, the remaining small intestine being anastomosed to the stomach after antrectomy. The procedure produces less diarrhea than does jejunoileal bypass.Chlorella vulgaris: A species of green microalgae in the family Chlorellaceae. It is used as a model organism for PHOTOSYNTHESIS, and as a food supplement (DIETARY SUPPLEMENTS).Phycodnaviridae: A family of DNA plant viruses that infect eukaryotic algae.Dental Papilla: Mesodermal tissue enclosed in the invaginated portion of the epithelial enamel organ and giving rise to the dentin and pulp.Coagulants: Agents that cause clotting.Nitrate Reductase (NADH): An NAD-dependent enzyme that catalyzes the oxidation of nitrite to nitrate. It is a FLAVOPROTEIN that contains IRON and MOLYBDENUM and is involved in the first step of nitrate assimilation in PLANTS; FUNGI; and BACTERIA. It was formerly classified as EC 1.6.6.1.Chlorophyta: A phylum of photosynthetic EUKARYOTA bearing double membrane-bound plastids containing chlorophyll a and b. They comprise the classical green algae, and represent over 7000 species that live in a variety of primarily aquatic habitats. Only about ten percent are marine species, most live in freshwater.Endolimax: A genus of ameboid protozoa found in the intestines of vertebrates and invertebrates.Photobioreactors: Devices for generating biological products that use light as the energy source. They are used for controlled BIOMASS production such as growing cyanobacteria, mosses, or algae.Nitrate Reductases: Oxidoreductases that are specific for the reduction of NITRATES.Piper betle: A plant genus of the family PIPERACEAE that is indigenous in the Indian Malay region and cultivated in Madagascar, and the West Indies. It contains chavibetol, chavicol and cadinene. The leaf is chewed as a stimulant, antiseptic and sialogogue. The common name of betel is also used for ARECA.DNA, Algal: Deoxyribonucleic acid that makes up the genetic material of algae.Algal Proteins: Proteins found in any species of algae.
