This study was conducted to assess three extraction methods for the determination of fatty acid compositions and carotenoids (lutein, zeaxanthin, β-carotene, and α-carotene) from marine microalgae, Nannochloropsis oculata (NO) and Chaetoceros gracilis (CG). For this purpose, three different extraction methods for the determination of fatty acids (dichloromethane:methanol, water:propan-2-ol:hexa...

This study aimed to evaluate the effect of rootstocks on fruit sugars, organic acids, and carotenoids. The contents of sugars and organic acids in fruits were determined by HPLC. Total acidity (TA), total soluble solids (TSS), and pH value of the juice were also evaluated. Total carotenoids and chlorophylls contents were measured using a spectrophotometer. The content of ethylene in fruits was ...

Upon depletion of Sll0254 in Synechocystis sp. strain PCC 6803, cyclized carotenoids were replaced by linear, relatively hydrophilic carotenoids, and the amount of the two photosystems decreased greatly. Full segregants of the sll0254 deletion in Synechocystis were not obtained, implying that this gene is essential for survival, most likely to allow normal cell division. The N-terminal half of ...

Carotenoids are known to possess immense nutraceutical properties and microorganisms are continuously being explored as natural source for production of carotenoids. In this study, pigmented bacteria belonging to Flavobacteriaceae family were isolated using kanamycin-containing marine agar and identified using the molecular techniques and their phenotypic characteristics were studied along with...

  Objective(s): Carotenoids which are naturally synthesized by fungi such as yeasts can act as an antioxidant which is closely related to their ability to decrease the risk of a variety of degenerative diseases. In recent years, the increase of demand for carotenoids obtained from natural sources has promoted major efforts to improve carotenoid production from biological sources such...

among the environmental stresses, salinity is a major limiting factor in world legumes production is considered. in this study, sodium chloride and salicylic acid interaction on growth parameters were investigated in greenhouse with factorial arrangement in randomized complete block design with three replications. the plant consisted of three cultivars of lentil (kimiya, kermanshah and gachsara...
