RESUMO

Several strains of Neurospora sp were isolated from beiju which is used for production of tiquira in various regions of the state of Maranhão. All isolated strains, including Nelfrospora sitophila ATCC 46892 wich was also isolated from beiju by Park et alii in 1982 have produced fruity aroma that was identified as ethy hexanoate. In this research was studied biochemical and morfological characteristics of all strains of Neurospora sp such as Neurospora sitophila NRRL 2884, N. tetrasperma NRRL 2164, N. intermedia NRRL 5506 and N. crassa NRRL 2223. It was found that these strains of Neurospora sp from beiju have produced the fruity aroma where as other strains of Neurospora sp did not. All strains of Neurospora from beiju pro.duced less amyloglucosidase and alcohol by fermentation than Neurospora sitophila NRRL 2884, but produced more than other strains of Neurospora sp. It was also found that all strains of Neurospora did not produced xylanase, pectinase, carboxymethylcellulase and lipase. It was found that all strains of Neurospora have ubiquinone Q-I0. Strains of Neurospora sp from beiju showed conidiation and pigmentation differents of strains of Neurospora NRRL. It was examined crossing only between strains of Neurospora from beiju and N. sitophila NRRL 2884. It was concluded that the strains of Neurospora sp isolated from beiju and N. sitophila NRRL 2884 are kind level, however have different biochemical and morfological characteristics
