Registro fotográfico de cepas de actinobactérias do semiárido

Abstract

The actinobacteria are the main soil microbial community components, corresponding to 77% out of total microorganisms. Due to its huge diversity among the actnobacteria, in relation to cultural aspect, the cultural characterization become an extremely relevant tool on classification and recognition of these organisms. A photographic collection of actinobacterias from northeast Brazilian semiarid region may contribute in studies of this group. Therefore, the objective of the current study was the cultural characterization and photographic register of 37 strains of actinobacteria coming from Quixeramobim – Ceará, in northeast Brazilian semiarid region. The colors black and white were picked as background, depending on spore mass color, on sample registration. Furthermore, the isolated bacterial colonies of each exemplar were shoot, indicating, in an evaluation of similarity criteria, that the actinobacteria are subdivided in 23 distinct color groups.
