Penicillium thomii PT95 strain is able to form abundant orange, sand-shaped sclerotia in which carotenoids accumulate. We have studied the effects of copper (Cu)-induced oxidative stress on sclerotial differentiation, biosynthesis of some endogenous antioxidants, and activities of a number of the antioxidative enzymes of strain PT95. The association between(More)
AIMS To determine the effect of oxidative stress and exogenous ascorbic acid on sclerotial biomass and carotenoid yield of Penicillium sp. PT95. METHODS In this experiment, high oxidative stress was applied by the inclusion of FeSO(4) in the growth medium and exposure to light. Low oxidative stress was applied by omitting iron from the growth medium and(More)
AIMS To determine the effect of oxidative stress and exogenous beta-carotene on sclerotial differentiation and carotenoid yield of Penicillium sp. PT95. METHODS AND RESULTS In this experiment, high oxidative stress was applied by inclusion of FeCl(3) (10 micromol l(-1)) in the growth medium and by light exposure. Low oxidative stress was applied by(More)
Oxidative stress and grains were evaluated for carotenoid production by solid-state fermentation using Penicillium sp. PT95. When the fungus was grown at high oxidative stress, its sclerotial biomass and carotenoid content in sclerotia increased significantly with respect to low oxidative stress (P < 0.01). High oxidative stress also caused a statistically(More)
[structure: see text] Two podands, 4,4'-[(ethylenedioxy)bis(ethyleneoxy)]bis[1-(2-imidazo[4,5-f]-1,10-phenanthroline)benzene] (1) and [Ru(phen)(2)](2)(1)(PF(6))(4) (2) complex, were synthesized from 1,10-phenanthroline. The photophysical behavior and the binding ability of 1 and 2 with some alkali metal and alkaline earth cations were investigated by UV-vis(More)
In order to quantitatively investigate their molecular binding ability, a series of cyclodextrin-crown ether conjugates containing beta-cyclodextrin (beta-CyD) and crown ether units, i.e.N-(benzoaza-15-crown-5)acylaminomethylene tethered 6-diethylenetriamino-6-deoxy-beta-CyD, N-(benzoaza-15-crown-5)acylaminomethylene tethered(More)
Human enterovirus 74 (HEV74) is a recently described serotype within the species Human enterovirus B (HEV-B). Few nucleotide sequences of HEV74 are available, and only one complete genome sequence (the prototype strain) has been published. In this study, we report the complete genome sequence of an HEV74 strain isolated from a healthy child during a stool(More)
Six kinds of elicitors were prepared respectively from Neurospora crassa, Monascus purpureus, Sporobolomyces roseus, Rhodotorula rubra, Nocardia sp. N89 and Actinoplanes sp. A05. When Penicillium sp. PT95 was incubated in Czapek's agar plates containing appropriate amounts of elicitors, both its sclerotia biomass and carotenoid content accumulated in(More)
The ability of the basidiomycete Hericium erinaceum to degrade starch and upgrade nutritional value of cornmeal during solid-state fermentation was studied. On the basal medium which consisted of cornmeal and salt solution, H. erinaceum produced a strong alpha-amylase on the 15th day after inoculation, which resulted in a 52% degradation of the starch. By(More)
Penicillium thomii PT95 strain was able to form abundant orange, sand-shaped sclerotia in which carotenoids were accumulated. The aim of this work was to determine the effects of copper-induced oxidative stress on the sclerotial differentiation and antioxidant properties of PT95 strain. The results showed that the time of exudates initiation, sclerotial(More)
