Background: Biosynthesis of nanoparticles using microorganisms, enzymes, and plant extracts is regarded as an alternative to chemical methods. Microalgae appear to be an efficient biological platform for nanoparticle synthesis as they grow rapidly and produce large biomass at lower cost. Objectives: The possibility of silver nanoparticles biosynthesisby freshwater green microalgae, Chlamydomona...

This study investigated effects of microalgae (Rhodomonas baltica) and heterotrophic protists (Oxyrrhis marina) on the daily growth, activity, condition and feeding success of Atlantic herring (Clupea harengus) larvae from hatch, through the end of the endogenous (yolk sac) period. Yolk sac larvae were reared in the presence and absence of microplankton and, each day, groups of larvae were prov...

In this review, we aim to explore the potential of microalgal biodiversity and ecology for biotechnological use. A deeper exploration of the biodiversity richness and ecophysiological properties of microalgae is crucial for enhancing their use for applicative purposes. After describing the actual biotechnological use of microalgae, we consider the multiple faces of taxonomical, morphological, f...

Due to its abundance and also flexibility of cultivation conditions, Chlorella vulgaris microalgae is one of the most ideal options available in order to production of microalgae based biodiesel. Since vulgaris cultivation for fuel production needs economic considerations to be taken, and in first place providing biomass and lipid production costs is important, wide researches have bee...

The carbon dioxide fixation by microalgae has several merits such as the COz recovery and the production of useful chemicals. Since the flue gas from a industry has some unfavorable conditions such a s high CQ concentration and toxic chemicals like SO., NO, contained in flue gas for the cultivation of m s t microalgae, it is important to apply a suitable strain of microalgae for the fixation of...

Microalgae represent a sustainable energy source because of their high biomass productivity and ability to remove air and water born pollutants. This paper reviews the current status of production and conversion of microalgae, including the advantages of microalgae biodiesel, high density cultivation of microalgae, high-lipid content microalgae selection and metabolic control, and innovative ha...

Antialgal activity of Zataria multiflora, Satureja khuzistanica and S. rechingeri were evaluated. These plant species are easily cultivable and their algicidal activity make them suitable candidate as biocontrol. This study aimed to identify effective algicidal compounds, practically new algicidal agents from essential oils of plants that could inhibit the growth of red tide microalgae. Prepare...

This study investigated the growth inhibition effects of three phenicol antibiotics on microalgae used in aquaculture. Different dose levels of chloramphenicol (CAP), florfenicol (FF), and thiamphenicol (TAP) were added to cultures of one freshwater green alga, Chlorella pyrenoidosa, and two marine algae, Isochrysis galbana and Tetraselmis chui. For the two marine algae, FF showed higher toxici...
