Аннотация

Increasing growth of world costs on petroleum and growing deficiency of petroleum products lead
to necessity of using alternative motor fuels. Thus, technology of using cyanobacteria as raw material for
fuel production has one of the central place among tools of modern alternative energetics, because they
are considered as more effective biological producers of natural hydrocarbons in the form of fatty acids.
This allows observing it as a unique renewable biomass source, which is suitable for rapid conversion
to biodiesel.
Nowadays, creation of such technology is actual and prospective; additionally it presents a great
interest for development of alternative energetics. This article generalize literature data about problems
of introducing the alternative “green” technologies and development on new field of industry – bioenergetics, about perspectives and possibilities of biofuel from photosynthetic microorganisms and their
preference among conventional sources of raw material. There are also data of experimental works on
screening of potential producers, optimization of cultivation of cyanobacteria for increasing the yield of
end product. In addition, possible ways of increasing efficiency of their energetical using with the help of
genetic engineering methods are reviewed. The main stages of technology of biodiesel fuel production
from phototrophic microorganisms are described and results of scientific investigations in this area, conducted in the framework of scientific-research projects on the basis al-Farabi Kazakh National University
are presented.
Key words: biofuels, biodiesel, microalgae, cyanobacteria, fatty acids, lipids.
