Abiogenesis

... Subjection to the temperature of boiling water for, say, half an hour seemed an efficient mode of sterilization, until it was discovered that the spores of bacteria are so involved in heat-resisting membranes, that only prolonged exposure to dry, baking heat can be recognized as an efficient process ...

Alexander Fleming

... of the painter James McNeil Whistler . Fleming was admitted to the club after he made "germ paintings," in which he drew with a culture loop using spores of highly pigmented bacteria. The bacteria were invisible while he painted, but when cultured made bright colours. Serratia marcescens - ...

Charles Darwin

... had similar organs differing only in complexity. In March 1827 Darwin made a presentation to the Plinian society of his discovery that black spores often found in oyster shells were the eggs of a skate leech. Darwin also sat Robert Jameson 's natural history course, learning about stratigraphic ...

Ethyl alcohol

... and dissolving their lipids and is effective against most bacteria and fungi , and many viruses , but is ineffective against bacterial spores . Because of this disinfectant property, alcoholic beverages can be stored for a long time. See also alcohol fuel alcoholic beverages ...

Gamete

... Gametes (in Greek : γαμέτες ) —also known as sex cells, germ cells, or spores —are the specialized cells that come together during fertilization (conception) in organisms that reproduce sexually . In those species ...

Lichen

... lichen, though it is more common in basidiomycetous lichens since they appear to lack structures specifically designed for asexual reproduction. spores are produced in spore producing bodies, the three most common spore body types are the apothecia , perithecia and the pycnidia . Ecology ...

Louis Pasteur

... would not allow dust particles to pass. Nothing grew in the broths; therefore, the living organisms that grew in such broths came from outside, as spores on dust, rather than being spontaneously generated within the broth. Thus, Pasteur dealt the death blow to the theory of spontaneous generation and ...

Neurospora crassa

... is a type of red bread mold of the phylum Ascomycota . The genus name, meaning "nerve spore" refers to the characteristic striations on the spores that resemble axons . N. crassa is notable for its use as a model organism in science because it is easy to grow and has a haploid life ...

Robert Koch

... the bacillus from blood samples and grow pure cultures. He found that, while it could not survive outside a host for long, anthrax built persisting spores that could last a long time. These spores, embedded in soil, were the cause of unexplained "spontaneous" outbreaks of anthrax. Koch published his ...
