Microalgae are primary producers of oxygen and exhibit an enormous
potential for biotechnological applications. Microalgae cultivation
is also an interesting option for wastewater treatment. These
microorganisms are efficient in recovering high amounts of
nitrogen, inorganic phosphorus, and heavy metals from effluents.
Furthermore, microalgae are responsible for the reduction of CO2
from gaseous effluent and from the atmosphere, reducing the
greenhouse gases effect. On the other hand, microalgae biomass can
be used for the production of pigments, lipids, foods, and
renewable energy. The culture of microalgae is not a new issue,
since for many decades they have been employed with aquaculture
purposes. In fact, some species of Nostoc, Arthrospira (Spirulina)
and Aphanizomenon species have been used as food for thousands of
years for food applications. The treatment of wastewaters employing
microalgae has been reported for decades (specifically for the
elimination of phosphorus and nitrogen compounds). Nowadays, there
is an increasing interest in the production of biofuels.
Bioethanol, biohydrogen, bio-methane, biodiesel and other novel
products can be obtained using microalgae as biomass or metabolic
products (sugars, lipids, etc). In the near future, microalgae can
be oriented (via molecular engineering) to the production of the
hole biofuels, such as biodiesel or bio-turbosins. Microalgae and
Other Phototrophic Bacteria is a book which will provide
information for academics students, policy makers and the general
public regarding the state of the art in the field, as well as
detailed descriptions of the methodologies employed for culture,
processing, recovery and new products. Aspects covered by this book
are the microalgae and other phototrophic bacteria.
In a world of declining fossil energy, biotechnology explores
multiple products and processes hidden in the rich genome of
microbes, plants and animals. One of the reasons for the renewed
spirit of biotechnology is supported by its capacity to swiftly
incorporate the multidisciplinary advances in basic and applied
sciences. This book presents a wide range of biotechnology research
by the UPIBI community, teachers and students in the past 24 years.
Novel methodologies, basic results and new processes are reported
in several of the most dynamic fields in biotechnology such as
health, energy, food and environment. This effort will certainly be
an inspiration for students wishing to join research teams, for
academic colleagues in search of new knowledge and for
professionals exploring novel ideas or innovative solutions.
