Slime coat, the coating of mucus covering the body of all fish; Slime mold, an informal name for several eukaryotic organisms; Biofilm, or slime, a syntrophic community of microorganisms in which cells stick to each other
A slime layer in bacteria is an easily removable (e.g. by centrifugation), unorganized layer of extracellular material that surrounds bacteria cells. Specifically, this consists mostly of exopolysaccharides , glycoproteins , and glycolipids . [ 1 ]
Brian Shaffer was the first to purify acrasin, now known to be cyclic AMP, in 1954, using methanol. [2] Glorin, the acrasin of P. violaceum, can be purified by inhibiting the acrasin-degrading enzyme acrasinase with alcohol, extracting with alcohol and separating with column chromatography.
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
Brefeldia maxima, a slime mold, examples have been reported up to a centimetre thick with a surface area of over a square metre and weighed up to around 20 kg [56] Xenophyophores, protozoans of the phylum Foraminifera, are the largest examples known, with Syringammina fragilissima achieving a diameter of up to 20 cm (7.9 in) [57]
Biochemistry or biological chemistry is the study of chemical processes within and relating to living organisms. [1] A sub-discipline of both chemistry and biology, biochemistry may be divided into three fields: structural biology, enzymology, and metabolism. Over the last decades of the 20th century, biochemistry has become successful at ...
A sundew with a leaf bent around a fly trapped by mucilage. Mucilage is a thick gluey substance produced by nearly all plants and some microorganisms.These microorganisms include protists which use it for their locomotion, with the direction of their movement always opposite to that of the secretion of mucilage.

An overview of the different components included in the field of chemical biology. Chemical biology is a scientific discipline between the fields of chemistry and biology.The discipline involves the application of chemical techniques, analysis, and often small molecules produced through synthetic chemistry, to the study and manipulation of biological systems.
