Carotenogenesis in diphenylamine-treated Epicoccum nigrum link

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1969
Abstract 1. 1. The effect of diphenylamine (1.0·10−5−1.0·10−3 M) has been studied on culture growth and carotenoid, ergosterol, fatty acid and protein synthesis in Epicoccum nigrum grown in submerged culture. 2. 2. Diphenylamine delayed total glucose uptake from about 80 h in normal cultures to about 160 h in 7.5 · 10−5 M diphenylamine ...

Protease and carotenogenesis in Blakeslea trispora

Phytochemistry, 1981
Abstract Carotene production by single and mated Blakeslea trispora has been studied. On mating and on the addition of trisporic acid to minus cultures there was an increase in the membrane bound neutral protease (MW 126 000) activity. The protease probably acts by inactivating the inhibitory protein of carotene biosynthesis resulting in increased ...

Carotenogenesis in Haematococcus pluvialis

Nature, 1955
IN a recent communication1, Goodwin and Jamikorn state that light is necessary for the synthesis of astaxanthin, the carotenoid responsible for the red colour in the alga Haematococcus pluvialis. It is not clear whether this conclusion is reached as a result of their own experience or whether they are referring to earlier information2.

End-product regulation of carotenogenesis in Phycomyces

Archives of Microbiology, 1988
Wild-type Phycomyces blakesleeanus synthesizes the yellow pigment, beta-carotene. Colour mutants exhibit various alterations in the biosynthesis of beta-carotene or in its regulation. The presence of certain chemicals in the medium stimulates carotenogenesis in the wild type. We attribute different mechanisms of action to agents which stimulate or fail

Relationship of lysozyme resistance to carotenogenesis in Micrococcus lysodeikticus

Biochimica et Biophysica Acta, 1961
1. I. Cells of Microccus lysodeikticus normally sensitive to lysozyme action contain yellow carotenoids, while cells which are resistant to lysozyme are devoid of extractable carotenoids and are white in color. Cultures of this organism that are partially resistant to Aureomycin are also partially deficient in carotenoid content and are lysed by ...

Effects of amines on the carotenogenesis in Blakeslea trispora

Phytochemistry, 1974
Abstract Six amines profoundly affected carotenogenesis in Blakeslea trispora . When cultures were treated with the amines, namely 4-[β-(diethylamino)-ethoxy]-benzaldehyde, 4-[β-(diethylamino)-ethoxy]-acetophenone hydrochloride, 4-β-(diethylamino)-ethoxy]-benzophenone hydrochloride, triethylamine hydrochloride, α-diethylaminopropiophenone ...

The effect of diphenylamine on carotenogenesis in Phycomyces blakesleeanus

Phytochemistry, 1983
Abstract The presence of diphenylamine (DPA) during growth of mutant strains of Phycomyces blakesleeanus caused the expected inhibition of the formation of unsaturated carotenes, and the accumulation of phytoene in all cases. Cell extracts from DPA-grown cultures incubated with [2- 14 C]mevalonic acid, also exhibited these effects.

Effect of Phytochrome on Carotenogenesis in Sorghum bicolor

Biochemie Und Physiologie Der Pflanzen, 1985
Summary Application of cycloheximide (25μg/ml) and 6 methyl purine (5μg/ml) continuously or only upto the 12 h of dark period subsequent to 5 min of red light irradiation completely inhibited phytochrome mediated push control and pull control of carotenogenesis in 5-day-old etiolated seedlings of Sorghum bicolor . The addition of these inhibitors 12

Fluence response relationship of carotenogenesis inNeurospora crassa

Planta, 1980
The fluence response of the blue light induced carotenoid synthesis inNeurospora is biphasic. Using fluence rates between 0.3 and 40 Wm(-2), increasing illumination times beyond 16 min (at 20°C) result in a second rise of the amount of carotenoids synthesized in the subsequent dark period. On altering the temperature, the transition point to the second
