Biosurfactants production by yeasts using soybean oil and glycerol as low cost substrate BJM
Accorsini,Fábio Raphael; Mutton,Márcia Justino Rossini; Lemos,Eliana Gertrudes Macedo; Benincasa,Maria.
Biosurfactants are bioactive agents that can be produced by many different microorganisms. Among those, special attention is given to yeasts, since they can produce many types of biosurfactants in large scale, using several kinds of substrates, justifying its use for industrial production of those products. For this production to be economically viable, the use of residual carbon sources is recommended. The present study isolated yeasts from soil contaminated with petroleum oil hydrocarbons and assessed their capacity for producing biosurfactants in low cost substrates. From a microbial consortium enriched, seven yeasts were isolated, all showing potential for producing biosurfactants in soybean oil. The isolate LBPF 3, characterized as Candida antarctica,...

Molecular analysis of the bacterial diversity in a specialized consortium for diesel oil degradation Rev. Bras. Ciênc. Solo
Paixão,Douglas Antonio Alvaredo; Dimitrov,Mauricio Rocha; Pereira,Rodrigo Matheus; Accorsini,Fábio Raphael; Vidotti,Maria Benincasa; Lemos,Eliana Gertrudes de Macedo.
Diesel oil is a compound derived from petroleum, consisting primarily of hydrocarbons. Poor conditions in transportation and storage of this product can contribute significantly to accidental spills causing serious ecological problems in soil and water and affecting the diversity of the microbial environment. The cloning and sequencing of the 16S rRNA gene is one of the molecular techniques that allows estimation and comparison of the microbial diversity in different environmental samples. The aim of this work was to estimate the diversity of microorganisms from the Bacteria domain in a consortium specialized in diesel oil degradation through partial sequencing of the 16S rRNA gene. After the extraction of DNA metagenomics, the material was amplified by...
