Abstract A body of factual information has accumulated during the past decade which, in general, supports or is compatible with the proposal of Porter and Lincoln on the mechanism of biosynthesis of carotenes. However, some information has been obtained which necessitates a revision in details of the proposed scheme.

Canadian Journal of Research, 1948
Kuhn and Winterstein reported the isolation of 2,6-dimethylnaphthalene from the products of pyrolysis of carotenoid pigments. The production of alkyl derivatives of phenanthrene and chrysene by the same type of cyclization can readily be formulated.

Formation of Carotene in vitro
Nature, 1960RESULTS presented in this communication indicate that both β-hydroxy β-methylglutarate and mevalonate may be considered precursors of carotene formation in an in vitro extract obtained from mycelial mats of the mould Phycomyces blakesleeanus. This extract, capable of synthesizing carotene, can also be used for establishing the existence of a back ...

Toxicology, 1985
The safety of beta-carotene, a widely distributed food colorant was assessed in tests with cells and in sub-chronic and chronic experiments with animals. Mutagenicity evaluations which included the standard Ames test and the micro-nucleus test of bone marrow cells from mice showed that beta-carotene exerted no mutagenic properties.

Considered to be an effective antioxidant, beta-carotene, a carotenoid that occurs naturally in many vegetables and fruits and that converts to vitamin A in the body, has been the subject of intensive cancer prevention research for decades,1; and is a commonly found supplement on the shelves of most supermarkets.

ζ-Carotene and other carotenes in a Phycomyces mutant
Phytochemistry, 1987Abstract Strain S442, a new mutant of the fungus Phycomyces blakesleeanus , has a greenish colour and a distinct green fluorescence under long-UV light. Carotene analyses reveal the presence of phytoene, ζ-carotene, phytofluene, an unidentified compound, and neurosporene (in descending order of abundance).
