Background: The genus Dunaliella (Class – Chlorophyceae) is widely studied for its tolerance to extreme habitat conditions, physiological aspects and many biotechnological applications, such as a source of carotenoids and many other bioactive compounds. Biochemical and molecular characterization is very much essential to fully explore the properties and possibilities of the new isolates of Duna...

conclusions light and temperature were both relevant factors that contributed to the growth and beta-carotene accumulation of the three d. salina strains, and nahco3 had significantly positive effects on growth. the degree of impact of the different factors on cell growth was temperature > nahco3 > light intensity > kno3 > co (nh2)2 > strains; the impact on beta-carotene accumulation was temper...

The microbial loop is the conventional model by which nutrients and minerals are recycled in aquatic eco-systems. Biochemical pathways in different organisms become metabolically inter-connected such that nutrients are utilized, processed, released and re-utilized by others. The result is that unrelated individuals end up impacting each others' fitness directly through their metabolic activitie...

objective: phototoxicity is a kind of dermatitis that is activated by exposure to ultraviolet light following the administration of some drugs or natural products. artemia salina (a. salina) (brine shrimp) has been effectively applied for toxicity testing and is perfect for biological screening of many chemicals for simultaneous evaluation of toxicity and phototoxicity. the objective of this st...

The present work investigates nitrate and phosphate removal from synthetic treated slaughterhouse wastewater in a novel open raceway pond with sedimentation zone. For this purpose, microalgae Chlorella salina has been cultivated in synthetic wastewater and sedimentation zone has been added to enhance both algae separation in the system and nutrient removal. The effectiveness of Chlorella salina...

Brine shrimp (Artemia salina) cytotoxicity assays (BSLT) are one of the commonly used cytotoxic test methods to assess a plant extract's pharmacological activity and toxicity. Thus, this study aimed examine toxic levels Kecubung (Datura metel) leaves extracted using different solvents, namely ethanol ethyl acetate. The results showed that LC50 value flower ethanol, acetate, leaf stem acetate ex...

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...
