“…The activity displayed by extracellular extracts was expected since previous studies on secondary metabolites with antimicrobial action were already conducted, showing the potential of organic extracellular extracts as sources of bioactive compounds (Henr ıquez et al 2014;Spago et al 2014). It is interesting to note that while none of intracellular extracts produced by the marine showed promising results, most of the extracts from soil isolates able to inhibit X. citri growth were extracted from the inside of cells.…”

This manuscript makes an impact on the study of micro-organisms from extreme habitats and their possible contribution in discovering new active molecules against pathogens of agricultural interest. Studies on the Antarctic continent and its communities have attracted the scientific community due to the long period of isolation and low levels of disturbance that surrounds the region. Knowing the potential of fungi in this region to produce active secondary metabolites, we aim to contribute to the discovery of compounds with antibacterial action in Xanthomonas citri subsp. citri, a plant pathogen present in several regions around the globe.

Bacterial wilt of tomato is a devastating disease incited by Ralstonia solanacearum (KK2) causing heavy yield loss in India. The antagonist Pseudomonas fluorescens (TNAU PF1) was characterized for antibacterial ability against the bacterial wilt pathogen. Thin-layer chromatography (TLC) identified six distinct antibiotics in crude metabolite of TNAU PF1 strain. The crude antibiotics and the antibiotics 2,4-diacetylphloroglucinol and Phenazine of TNAU PF1 showed best in vitro antibacterial activity against the bacterial wilt pathogen R. solanacearum. The ability of crude antibiotics in inhibiting Ralstonia colonies was higher than the individual antibiotics (2,4-diacetylphloroglucinol and Phenazine) under in vitro. Further, GC-MS analysis of the semi-purified crude extract of Pseudomonas fluorescens (TNAU PF1) identified six antibacterial compounds viz., Phloroglucinol dimethyl ether, Patulin, Hemipyocyanin, Phthalic acid, butyl 2-pentyl ester, Phenazine and 1-Phenazinecarboxylic acid that would be synergistically inhibited the colony multiplication of the pathogen. The study emphasized the antagonistic activity of the Pseudomonas fluorescens (TNAU PF1) for the management of bacterial wilt disease.

The objective of this work was to evaluate the effect of foliar spraying with bacterial biocontrol agents (BBAs) on the control of common bacterial blight (CBB) of bean, and on the induction of systemic resistance in bean plants. CBB control by BBAs was evaluated by spraying bean leaves 48 and 24 hours before and after pathogen inoculation (BPI and API, respectively), with: DFs93, Bacillus cereus; DFs513, Pseudomonas veronii; DFs769, B. cereus; the C01 combination, DFs93 + DFs769 + DFs831 (Pseudomonas fluorescens); the C03 combination, DFs348 (Bacillus sp.) + DFs769 + DFs831; and water (control). Systemic effects were analyzed after spraying DFs513, DFs769, C03, and water 72 and 48 hours BPI. Phaseolin production induced by DFs348, DFs513, DFs769, DFs831, and water was also assessed. DFs513, DFs769, and C03 significantly reduced disease incidence (area under disease progress curve), regardless of spraying time and disease severity when sprayed 72 and 48 hours BPI. The DFs769 and DFs831 isolates induced the accumulation of phytoalexin (phaseolin). Therefore, DFs513, DFs769, and C03 show potential for the biocontrol of CBB when applied preventively on bean leaves, besides inducing systemic resistance.
