“…Inhibitory metabolites produced by isolates of Serratia include pyrrolnitrin, oocydin A, carbapenem, prodigiosin, and serrawettin as well as chitinase and other cellwall and cell-membrane degrading enzymes (Lindum et al, 1998;Asano et al, 1999;McGowan et al, 1999;Strobel et al, 1999;Kamensky et al, 2003). Isolates of Burkholderia have been shown to produce pyrrolnitrin, altericidins, and other compounds with anti-biotic activity (Kirinuki et al, 1984;Roitman et al, 1990;Burkhead et al, 1994;Kang et al, 1998). T. virens GL3 and GL21 produce the antibiotics glioviren and gliotoxin, respectively, as well as a number of other inhibitory metabolites (Lumsden et al, 1992;Howell et al, 1993).…”

Lewis, Jack A.; and Chung, Soohee, "Biocontrol agents applied individually and in combination for suppression of soilborne diseases of cucumber" (2005 AbstractThe soilborne pathogens Rhizoctonia solani, Pythium ultimum, and Meloidogyne incognita can cause severe economic losses to field-and greenhouse-grown cucumber. A collection of bacterial isolates and isolates GL3 and GL21 of Trichoderma virens were screened for suppression of diseases caused by these pathogens. T. virens isolates GL3 and GL21 provided the most effective suppression of damping-off caused by R. solani in greenhouse bioassays. Burkholderia ambifaria BC-F, B. cepacia BC-1, and Serratia marcescens N1-14 also provided significant suppression of R. solani relative to the pathogen check in some experiments. T. virens isolates GL3 and GL21 and S. marcescens isolates N1-6, N1-14, and N2-4 provided the most consistent and effective suppression of damping-off of cucumber caused by P. ultimum in growth chamber experiments. No microbial treatment containing individual or combined microbes significantly suppressed populations of M. incognita on cucumber or improved plant vigor in greenhouse bioassays. T. virens GL21 applied as a granular formulation, in combination with B. cepacia BC-1 or B. ambifaria BC-F applied as a seed treatment, significantly improved suppression of damping-off caused by R. solani over individual applications of these microbes in at least one experiment. Treatments combining B. cepacia BC-1, B. ambifaria BC-F, or S. marcescens isolates N1-14 or N2-4 with T. virens GL21 in R. solani biocontrol assays always resulted in plant stands that were similar or greater than treatments containing individual applications of these microbes. B. ambifaria BC-F combined with T. virens GL21 in seed treatments resulted in significantly improved suppression of damping-off caused by P. ultimum in two of three experiments. Populations of T. virens GL3 and GL21 were both substantially reduced after coincubation with B. cepacia BC-1, or S. marcescens isolates N1-14 or N2-4 for 10 to 12 d in cucumber rhizospheres. Populations of T. virens GL21 were slightly reduced after coincubation with B. ambifaria BC-F.

These results also indicate that antagonism among combinations of biocontrol agents can vary with the assay system employed. r

“…The compound MSSP2 displays an inhibitory effect against P. ultimum, P. capsica , and S. sclerotiorum. Altericidins A , B , and C produced by B. cepacia KB-1 can inhibit a wide range of fungi and yeasts, such as Alteraria kikuchiana and Ustilago maydis , but has no effect on bacteria [ 134 ]. Rhamnolipids (Rha) are glycolipidic biosurfactants consisting of rhamnose molecules linked through a β-glycosidic bond to 3-hydroxyfatty acids with various chain lengths produced by bacterial species with several functions such as antimicrobial activity [ 135 ].…”

Compilation of the Antimicrobial Compounds Produced by Burkholderia Sensu Stricto

et al. 2023

Due to the increase in multidrug-resistant microorganisms, the investigation of novel or more efficient antimicrobial compounds is essential. The World Health Organization issued a list of priority multidrug-resistant bacteria whose eradication will require new antibiotics. Among them, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacteriaceae are in the “critical” (most urgent) category. As a result, major investigations are ongoing worldwide to discover new antimicrobial compounds. Burkholderia, specifically Burkholderia sensu stricto, is recognized as an antimicrobial-producing group of species. Highly dissimilar compounds are among the molecules produced by this genus, such as those that are unique to a particular strain (like compound CF66I produced by Burkholderia cepacia CF-66) or antimicrobials found in a number of species, e.g., phenazines or ornibactins. The compounds produced by Burkholderia include N-containing heterocycles, volatile organic compounds, polyenes, polyynes, siderophores, macrolides, bacteriocins, quinolones, and other not classified antimicrobials. Some of them might be candidates not only for antimicrobials for both bacteria and fungi, but also as anticancer or antitumor agents. Therefore, in this review, the wide range of antimicrobial compounds produced by Burkholderia is explored, focusing especially on those compounds that were tested in vitro for antimicrobial activity. In addition, information was gathered regarding novel compounds discovered by genome-guided approaches.

Members of the genus Burkholderia are known for their ability to suppress soil-borne fungal pathogens by the production of various antibiotic compounds. In this study we investigated the role of N-acylhomoserine lactone (AHL)-dependent quorum sensing (QS) in the expression of antifungal traits. Using a quorum quenching approach, that is, by heterologous expression of the Bacillus sp. AiiA lactonase, we show that expression of antifungal activities is AHL-dependent in the large majority of the investigated strains belonging to various Burkholderia species. We demonstrate that in certain strains of Burkholderia ambifaria, Burkholderia pyrrocinia and Burkholderia lata, one of the QS-regulated antifungal agents is pyrrolnitrin (prn), a common broad-spectrum antibiotic that is also produced by some Pseudomonas and Serratia species. To investigate the underlying molecular mechanisms of AHL-dependent prn production in better detail, we inactivated the AHL synthase cepI as well as cepR, which encodes the cognate AHL receptor protein, in B. lata 383. Both QS mutants no longer produced prn as assessed by gas chromatography-mass spectrometry analysis and as a consequence were unable to inhibit growth of Rhizoctonia solani. Using fusions of the lacZ gene to the promoter of the prnABCD operon, which directs the synthesis of prn, we demonstrate that expression of prn is positively regulated by CepR at the level of transcription.
