Modeling Growth of Microalgae Dunaliella Salina under Different Nutritional Conditions
Problem statement: The aim of this study was to find the empirical model that describes the growth kinetics of Dunaliella salina, with low production cost and to estimate parameters of this model. Approach: In this study the strain of D. salina UTEX 200 was cultivated in seawater (0.5 M NaCl) at room temperature with agitation of 150 rpm and luminous intensity of 60 mmols.m-2.s-1. The synthetic...
متن کاملPotential of new isolates of Dunaliella salina
The halotolerant microalga Dunaliella salina has been widely studied for natural 10 β-carotene production. This work shows biochemical characterization of three newly isolated 11 Dunaliella salina strains DF15, DF17 and DF40 compared with D. salina CCAP 19/30 (confirmed to 12 be D. tertiolecta) and D. salina UTEX 2538 (also known as D. bardawil). Although all three new strains 13 have been gene...
متن کاملEffect of salinity on the quantity and quality of carotenoids accumulated by Dunaliella salina (strain CONC-007) and Dunaliella bardawil (strain ATCC 30861) Chlorophyta.
Dunaliella salina and D. bardawil are well-known microalgae accumulating high levels of beta-carotene under growth-limiting conditions. In both taxa, this pigment is primarily composed of the isomers 9-cis and all-trans. The 9-cis beta-carotene occurs only in natural sources and is the most attractive from a commercial point of view. The conditions that enhance the preferred accumulation of 9-c...
متن کاملEffect of SiO2 Nanoparticles on Chlorophyll, Carotenoid and Growth of Green Micro-Algae Dunaliella salina
As a rapidly-evolving global technology, nanotechnology has presumably brought drastic changes to our lives in the past two decades using engineered nanoparticles, whose penetration into industrial and non-industrial wastewater requires examination of their probable effects in aquatic ecosystems. The main objective of this work is to study the toxicological and biological effects of nanomateria...
متن کاملThe effect of temperature and irradiance on the growth and carotenogenic capacity of seven strains of Dunaliella salina (Chlorophyta) cultivated under laboratory conditions.
The carotenogenic microalga Dunaliella salina is cultivated as a natural source of beta-carotene. The 9-cis isomer of beta-carotene is found only in natural sources having commercial advantages over the all-trans isomer due to its high liposolubility and antioxidant power. High irradiance appears to stimulate specifically all-trans beta-carotene accumulation in D. salina, whereas low temperatur...
