Effect of Vanadate and Iron Stress on the Pigment Composition of Chlorella fusca

چکیده
Carotenoids, Chlorella fusca, Chlorophylls, Iron Stress, Vanadate The pigment composition of Chlorella fusca has been investigated in the absence and in presence of vanadate and during iron stress. 1. Fe-deficiency generally decreases algal pigment content without change of the ratio chloro phyll a/b. 2. A twofold vanadate induced increase of the chlorophylls is accompanied by a similar enhancement of several xanthophylls, while lutein remains unaffected. 3. Vanadate stimulates the formation of ^-carotene up to 5 fold, the effect being less obvious during iron stress.

متن کاملThe effect of Melatonin pretreatment on growth responses and enhancement of the enzyme's antioxidant system in Chlorella vulgaris under stress of ionizing radiation
Melatonin has important roles in many growth and stress-related responsive processes in plants and algae. In this study, the mediating role of 100 and 500 µM melatonin on photosynthetic pigments and non-enzymatic antioxidant responses of microalga, Chlorella vulgaris to gamma irradiation stress has been studied. The result showed that the alga treated with 100 µM had a stable amount of chloroph...
متن کاملThe effect of Melatonin pretreatment on growth responses and enhancement of the enzymatic antioxidant system in Chlorella vulgaris under stress of ionizing radiation
Melatonin as a compound made by photosynthetic organizers protects them against many environmental stresses. Modulating mechanisms of melatonin, as a protector are not well known in early eukaryotes, such as algae. In this research, the effect of melatonin pre-treatment on evaluating Chlorella vulgaris resistance to gamma ionizing radiation was investigated. The results showed that 100 µM conce...
متن کاملTiO2 Pigment Suspension Behaviour upon Adsorption of Polymeric Dispersants
The influence of polymeric dispersants containing different functional groups on TiO2 pigment particle suspension was investigated at pH 6.0 and 9.5, using rheology and particle size data. The dispersants chosen were polyacrylic acid and modified polyacrylamides including homo and copolymers modified with carboxylate and/or hydroxyl groups. The pigment suspension was strongly affected by both p...
