Description
Summary:The use of fossil resources in industrial processes results in increasing environmental impact. Microorganisms from extreme environments have unique characteristics that guarantee their survival in cold regions. Bacteria from the Antarctic continent have potential for hydrocarbon production, offering a new sustainable energy source for biofuel production. The present work aimed the evaluation of hydrocarbons production from bacteria isolated from marine samples from the Antarctic continent. Six bacteria isolated were cultivated in the lipid extraction culture medium. Lipid extraction was performed with a chloroform/methanol/water mixture and confirmed by thin layer chromatography. The evaluation of the dry mass allowed to observe a standard microbial growth among the strains. Chromatographic analyses showed that lipid extraction was efficient, yielding lipids between C3-C18. Future studies must to be performed to exploring microbial adaptation to these extreme conditions. Results confirmed the potential of bacteria from extreme environments to produce compounds for biotechnological application. A utilização dos recursos fósseis em processos industriais, vêm, cada vez mais, acarretando um grande impacto ambiental. Micro-organismos de ambientes extremos possuem características únicas que garantem sua sobrevivência nestas regiões. Bactérias do continente Antártico apresentam potencial para produção de hidrocarbonetos, que possibilita uma nova fonte energética sustentável para a produção de biocombustível. O presente trabalho objetivou a avaliação da produção de hidrocarbonetos por bactérias isoladas de amostras marinhas do continente Antártico. Seis bactérias isoladas, foram cultivadas em meio de cultivo para extraçção de lipídeos. A extração dos lipídios foi realizada com uma mistura de clorofórmio/metanol/água, sendo confirmados por cromatrografia em camada delgada. A massa seca foi determinada, o que permitiu observar um crescimento microbiano padrão entre as linhagens. As análises cromatográficas mostraram ...
