ORTEGA-DIAZ, Yadenis; GOMEZ-LUNA, Liliana  y  SILVEIRA-FONT, Yadira. Development and characterization of a cyanobacteria consortium isolated from rhizospheres’ soil of Carica papaya. RTQ [online]. 2023, vol.43, n.2, pp.368-389.  Epub 30-Mayo-2023. ISSN 2224-6185.

Currently, biotechnological advances demonstrate the potential of cyanobacteria in various areas, thus becoming a group of high economic value. The objective of this study was to obtain and develop, by biotechnological means, a consortium of cyanobacteria isolated from the rhizospheric soil of Carica papaya. The culture was carried out in BG110 culture medium, with aeration of 0,32 Lmin-1, at a light intensity of 48,83 μEm-2s-1, with a temperature of 22 oC ± 2. A consortium formed was isolated and developed. by the species Nostoc commune, Calothrix sp. and Aphanothece mitussima. The effective development of this consortium at the laboratory level is verified, with values of chlorophylls, carotenes, proteins and lipids at the end of the test of 0,18 ±0,02 µgmL-1, 0,12 ±0,004 µgmL-1, 31, 25±8,49% and 13,92±2,95 % respectively, and a decrease in nitrate concentrations of 4,03±0,12 mgL-1 in the medium. The highest values of phycocyanin were obtained 21 days after the start of the experiments (4,38±0,001 µgmL-1), which allows expanding the spectrum of microorganisms obtained from the rhizosphere with potential stimulators.
