The objective of this work was to evaluate the capacity of mangrove microorganisms to control root rot, caused by Pythium aphanidermatum, and to promote growth in hydroponic cucumbers. Nineteen microorganisms were evaluated for controlling the disease in small-scale hydroponic units. The promising microorganisms – Gordonia rubripertincta SO-3B-2, and the combination of strains (G. rubripertincta SO-3B-2, MB-P3A-49, MB-P3-C68 and SO-3L-3 of Pseudomonas stutzeri, and Bacillus cereus AVIC-3-6 were subsequently evaluated in hydroponic cucumbers, in the greenhouse. Mangrove microorganisms can have an important functional role in the biological control of root rot caused by P. aphanidermatum, and in the growth promotion of cucumber plants cultivated in hydroponic systems. Gordonia rubripertincta SO-3B-2 and P. stutzeri MB-P3A-49 are promising growth promoters for non-infected plants.Downloads
