Cyanobacteria are photosynthetic microorganisms which can be found in various environmental habitats. These photosynthetic bacteria are considered as promising feedstock for the production of the third‐ and the fourth‐generation biofuels. The main subject of this review is highlighting the significant aspects of the biofuel production from cyanobacteria. The most recent investigations about the extraction or separation of the bio‐oil from cyanobacteria are also adduced in the present review. Moreover, the genetic engineering of cyanobacteria for improving biofuel production and the impact of bioinformatics studies on the designing better‐engineered strains are mentioned. The large‐scale biofuel production is challenging, so the economic considerations to provide inexpensive biofuels are also cited. It seems that the future of biofuels is strongly dependent to the following items; understanding the metabolic pathways of the cyanobacterial species, progression in the construction of the engineered cyanobacteria, and inexpensive large‐scale cultivation of them.

“…In this way, Brazilian researchers have been studying some alternatives to improve the contribution of these biofuels to the energy matrix. In the case of biodiesel we can cite microalgae [12] and cyanobacteria [13] produced naturally, and some types of non-edible plant oils, such as Jatropha curcas, castor bean, Murumuru, buriti, and pracaxi, can play a considerable role in the supply of alternative feedstock. On the other hand, they require a large available farmland [7,14].…”

This chapter intends to bring an overview about the Brazilian researches and their contributions to the production of biodiesel from wastes. Currently, the main obstacles to spread the use of biodiesel are its high cost of production and the competition between biodiesel and food industries. So, the use of wastes plays an important role in reducing the biodiesel costs and reusing the materials that have no other applications, as deodorization residues, neutralization soap sticks, and animal fats, among others. Then, we present a review about Brazilian studies involving waste oils and fatty-acid-rich raw materials that helped the advancement in this field of knowledge during the last few years.

Cyanobacteria are photoautotrophic prokaryotes that show a wide morphological and metabolic variety, which favors the colonization of the most diverse types of environments. This versatility reflects in its numerous biotechnological applications in areas such as agriculture, energy, nutrition and effluent treatment. With the increasing in energy and food demand, cyanobacteria are considered a more sustainable alternative for the biosynthesis of products of industrial interest. In this context, the aim of this study was to evaluate the cyanobacteria growth in media supplemented with vinasse and its effect on lipid production and fatty acid composition, with focus on biodiesel production. So, eleven cyanobacterial strains from water samples from Amazonian rivers were morphologically and genetically identified as belonging to four orders-Nostocales, Chroococciodipsidales, Synecoccocales e Oscillatoriales. These strains had their growth evaluated in culture media supplemented with vinasse (1, 2,5, 5 and 10% v/v) and in vinasse diluted in ultrapure water (2,5, 5 and 10% v/v). All strains were able to grow at the concentrations tested, however, at higher vinasse concentrations, growth inhibition and/or higher heterotrophic contaminants proliferation was observed. In vinasse diluted in ultrapure water, none of them were able to grow. Two cyanobacterial strains were selected for subsequent analysis due to rapid growth (Planktothrix mougeotii CMAA1564) and favorable fatty acid profile for biodiesel production (Amazoninema brasiliense CMAA1602, a new genus). Then, these strains had their gowth investigated in the media BG11, BG11+1% and BG11+2,5% of vinasse using the gravimetric (dry biomass) and spectrophotometric (optical density-OD680nm e OD750nm) methods, for growth phases identification. The highest lipid and biomass productivities were observed in the biomass collected in the log phase in medium supplemented with 1% of vinasse, wtith the highest values observed for the P. mougeotii CMAA1564 (3,18 e 35,87 mg L-1 dia-1 , respectively). The fatty acid profile of the lipid fraction showed the predominance of saturated and monounsaturated fatty acids in the oils of biomass grown in vinasse medium, with palmitic, palmitoleic, oleic and alpha-linolenic acids being the majority. From the fatty acid composition of the oils, it was possible to estimate eleven quality parameters of the biodiesel derived from these lipid feedstocks. Most of the properties evaluated werein accordance with the biodiesel quality specification estabilished in the national and international legislation, except for the kinematic viscosity that presented lower values. These results are promising given the opportunity for exploiting the underestimated cyanobacteria diversity for biotechnological purposes. This research shows the feasibility of using the lipid content of these organisms as an alternative lipid feedstock for biodiesel production.
