The green microalga Haematococcus pluvialis accumulates astaxanthin, a potent antioxidant pigment, as defense mechanism against environmental stresses. In this study, we investigated the technical feasibility of stress-based method for inducing astaxanthin biosynthesis in H. using electric stimulation two-chamber bioelectrochemical system. When cathodic (reduction) current 3 mA (voltage: 2 V) w...

This article presents materials on the results of an experiment enrichment Artemia salina with unicellular alga Haematococcus pluvialis to increase its nutritional value. For fry marine fish, such as mullet and kalkana, freshwater clary catfish, carp trout, supply fatty acids energy value is still insufficient. Therefore, it necessary enrich brine shrimp additional nutrients The use a component...

The carotenoid pigment astaxanthin has important applications in the nutraceutical, cosmetics, food and feed industries. Haematococcus pluvialis is the richest source of natural astaxanthin and is now cultivated at industrial scale. Astaxanthin is a strong coloring agent and a potent antioxidant - its strong antioxidant activity points to its potential to target several health conditions. This ...

A parasite was found in cultures of the green microalga Haematococcus pluvialis that grew epibiotically on algal cells and caused epidemics resulting in damage to the host cultures. The parasite was isolated into axenic culture on solid and liquid media. It was demonstrated to be the sole causative agent of the epidemics. According to its life cycle and phylogenetic analysis based on 18S riboso...

A periodic shading mechanism (about 0.5 s period) is believed to be used by flagellated algae to detect light direction. Time changes in the orientation of a population of Haematococcus pluvialis under positive photoaxis conditions (cell samples were stimulated alternatively by two diametrically opposed beams of actinic light), have been investigated by analysing the Doppler shifts of laser lig...
