The marine microalgae Dunaliella salina holds significant economic value due to its rich content of β-carotene, a natural pigment with high antioxidant capacity, immune-stimulating properties, and crucial role in reactions vitamins C E. This study evaluated the effects light factors on growth biosynthesis β-carotene strain isolated from coastal waters Central Vietnam. was cultured static f/2 me...
The harmful effects of ultraviolet (UV) radiation have increased the demand for new sources UV photoprotectants to develop cosmetic and skin care products. In this study, a filamentous cyanobacterial strain was isolated from topsoil collected in an arid exposed region Chetimari, Niger. On basis 16S rDNA sequences, identified as Pseudanabaena sp. CCNU1. UV-B treatment CCNU1 significantly enhance...
Most Sphingomonas species synthesize the yellow carotenoid nostoxanthin. However, the carotenoid biosynthetic pathway of these species remains unclear. In this study, we cloned and characterized a carotenoid biosynthesis gene cluster containing four carotenogenic genes (crtG, crtY, crtI and crtB) and a β-carotene hydroxylase gene (crtZ) located outside the cluster, from the gellan-gum producing...
1 of 2 DESCRIPTION A 30-month-old boy presented with yellowish discolouration of the nose ( fi gure 1 ), for 4 months. He was born prematurely at 32 weeks gestation with atrial and ventricular septal defects; both repaired in March 2009. Also has asthma and gastro-oesophageal refl ux. He is on erythromycin 16 mg four times a day, omeprazole 5 mg once daily, fl exitide 50 2 puffs twice daily, ph...
BACKGROUND Epidemiologic studies examining associations between carotenoid intakes and risk of breast cancer by estrogen receptor (ER) and progesterone receptor (PR) status are limited. OBJECTIVE We investigated these associations in a pooled analysis of 18 cohort studies. DESIGN Of 1,028,438 participants followed for a maximum follow-up of 26 y across studies, 33,380 incident invasive brea...
In photosynthetic organisms, carotenoids serve essential roles in photosynthesis and photoprotection. A previous report designated CruP as a secondary lycopene cyclase involved in carotenoid biosynthesis [Maresca J, et al. (2007) Proc Natl Acad Sci USA 104:11784-11789]. However, we found that cruP KO or cruP overexpression plants do not exhibit correspondingly reduced or increased production of...
Lycium chinense is a shrub that has health benefits and is used as a source of medicines in Asia. In this study, a full-length cDNA clone encoding β-ring carotene hydroxylase (LcCHXB) and partial-length cDNA clones encoding phytoene synthase (LcPSY), phytoene desaturase (LcPDS), ξ-carotene desaturase (LcZDS), lycopene β-cyclase (LcLCYB), lycopene ε-cyclase (LcLCYE), ε-ring carotene hydroxylase ...
This study was done on one nurseries affiliated to the center of Najaf governorate during growing season 2021-2022 corresponding 25/11/2021 determination effect Irrigation with magnetically treated water three intensity (0, 750, 1500) gauss and uses Super Micro Nano-fertilizer levels, first level (0 g.L-1), second (1 g.L-1) third (2 g.L-1). On some physiological indicators in pepper (Capsicum a...
Climate change and global warming generate serious consequences disturbances by drastically modifying historical temperature precipitation patterns. Water scarcity is one of the most revealing phenomena these instabilities. This transdisciplinary bibliometric economic–financial research focuses on analyzing two aspects: first, feasibility implementing seawater desalination plants as a solution ...
