Microalgal Species

Abstract: More than 90% of herbal products and herbal medicines have been derived from higher plants recently, but due to independent circumstances, several photosynthetic microalgal species are in focus in this point of view. In the last 50 years, many carbohydrate-, peptide-, terpenoid-, alkaloid- and phenol-type components were described from algae because of the developing structural determination and analytical methods, algae mass production and also artificial algae technologies. At the same time, based partly on traditional causes and partly on the clinical and preclinical data of today, some dried products of algae are directly used as food supplements. Hereinafter, the historical background, economic significance and metabolic background of the mostly used microalgal species will be reviewed. The diverse metabolite production of these organisms will be demonstrated by some molecules with special bioactivity. Several preclinical and clinical studies will be described relating to the microalgal species Spirulina sp., Chlorella sp., Haematococcus sp. and Dunaliella sp. Orv Hetil. 2018; 159(18): 703–708.

The work presented consists of a test procedure applied at a pilot scale using soil as a biological degradation agent. The experiments described were carried out with oily residues considered as wastes difficult to degrade by other means. The tests were applied to filter cake with activated clay containing 40% oil and oily residues from re-refining of lubricants to give white oils and vaseline. The effect of the amount of moisture is evaluated using a mechanical stirrer to improve the interaction between the wastes and microorganisms. The following are also evaluated: nutrient availability; incorporation of micro-organisms into the soil; introduction of chemical fertilizers; and, injections of sludge from effluent treatment plants.
