Diversity of a chlorine-resistant Bacillus population isolated from a wastewate...
Paes, Fernanda Araújo; Hissa, Denise Cavalcante; Angelim, Alysson Lira; Pinto, Natasha W.; Grangeiro, Thalles B.; Melo, Vânia M. M.This paper describes the phenotypic and genotypic diversity of a Gram-positive, aerobic bacterial population isolated from the chlorine tank of a wastewater treatment plant. A total of 12 spore- forming, rod-shaped isolates were identified using 16S rRNA gene sequencing and biochemical tests. Pairwise genetic comparisons revealed the identity among sequences obtained from isolates varied from 92.6 to 100%. Simi...

Barreto, R.V.G.; Hissa, Denise Cavalcante; Paes, Fernanda Araújo; Grangeiro, T. B.; Nascimento, R. F.; Rebelo, Luciana Magalhães; Craveiro, A. A.Spores ofBacillus subtilisLAMI008 were entrapped in 3-mm chitosan beads and cross-linked with 0.3%glutaraldehyde forn-hexadecane biodegradation and biosurfactant recovery. When exposed to nutrients,the spores generated vegetative cells without morphological alterations as revealed by atomic forcemicroscopy. The entrapped cells degraded almost 100% of 1% ofn-hexadecane in medium supplementedwith 1% glucose and p...
