The development of entrepreneurship is based on new developments in the field of science, which is current worldwide. Cyanobacteria have become nutritional supplements that develop entrepreneurship in the pharmaceutical field, as sources of biologically active substances. Some cyanobacteria are sources of vitamins and proteins such as Spirulina platensis, others are sources of carbohydrates such as Nostoc species. At the same time, the use of cyanobacteria as biostimulators in the growth of crop plants and increasing the yield is being developed. The more accelerated growth of tomatoes, cucumbers and medicinal plants was demonstrated, which demonstrates the high economic efficiency of these organisms. The LCȘ Phycobiotechnology and Animal Physiology investigations highlighted the usefulness of cyanobacteria obtained in pure culture from R. Moldova soils and in the sanogenic field. So, it is current and extremely important to study cyanobacteria and to develop new technologies for entrepreneurial development.
