“…The composition of the culture medium can affect the production of inhibitory substances [ 53 , 54 ] and consequently the establishment of antagonistic relations among microorganisms [ 24 , 30 ]. The validation of the compatibility of the strains selected to formulate the bacterial consortium was performed using growth curves under different culture conditions to evaluate any inhibitory relationships.…”

“…Bacteria were grown individually or together in SYP and PY-Ca liquid medium at 30°C and 200 rpm for 120 hours; each culture was generated in triplicate. The number of cultivable cells was quantified in quintuplicate using the MSDP method with selective medium plates to identify any inhibitory relationships among the co-inoculated strains as described in other works [ 24 , 30 ].…”

Compatible bacterial mixture, tolerant to desiccation, improves maize plant growth

Plant growth-promoting rhizobacteria (PGPR) increase plant growth and crop productivity. The inoculation of plants with a bacterial mixture (consortium) apparently provides greater benefits to plant growth than inoculation with a single bacterial strain. In the present work, a bacterial consortium was formulated containing four compatible and desiccation-tolerant strains with potential as PGPR. The formulation had one moderately (Pseudomonas putida KT2440) and three highly desiccation-tolerant (Sphingomonas sp. OF178, Azospirillum brasilense Sp7 and Acinetobacter sp. EMM02) strains. The four bacterial strains were able to adhere to seeds and colonize the rhizosphere of plants when applied in both mono-inoculation and multi-inoculation treatments, showing that they can also coexist without antagonistic effects in association with plants. The effects of the bacterial consortium on the growth of blue maize were evaluated. Seeds inoculated with either individual bacterial strains or the bacterial consortium were subjected to two experimental conditions before sowing: normal hydration or desiccation. In general, inoculation with the bacterial consortium increased the shoot and root dry weight, plant height and plant diameter compared to the non-inoculated control or mono-inoculation treatments. The bacterial consortium formulated in this work had greater benefits for blue maize plants even when the inoculated seeds underwent desiccation stress before germination, making this formulation attractive for future field applications.

“…The numbers of T. ptyseos growing for 96 h in liquid co-culture with the isolate UAPS07070 were three orders of magnitude less thant when growing alone (MarinCeVaDa et al, 2012). the antagonistic bacterium was also able to abate the brownish pigmentation of culture medium produced by the pathogen in cocultures (MaRíN-CeVaDa et al, 2012). It is still unknown if that observation was caused by the drop of T. ptyseos population itself, or by an inhibition of the oxidation pathway.…”

“…Among dozens of isolates from pineapple plants, two of them that showed the greatest inhibitory activity in culture media against T. ptyseos, where selected for determining their activity in assays in association with plants ( MaRíN-CeVaDa et al, 2012). The antagonism assays were carried out in double-layer plates, in liquid cultures, and in micropropagated inoculated pineapple plantlets (cv.…”

ABSTRACT-Pink disease is an asymptomatic pineapple disease in the field and is evidenced with a reddark coloration when the infected fruit is processed to obtain products such as juice, jam, and preservatives. Tatumella morbirosei and T. ptyseos (formerly Pantoea citrea) have been demonstrated as causal agents. although T. morbirosei and T. ptyseos have been well studied, there are currently no cost effective control methods in pineapple cultivation. The purpose of this review is to summarize the significant and updated research on the role of pink disease in pineapple.

“…In addition, antimicrobial activity has been detected for a number of distinct species of Burkholderia , and include, B. bryophila , B. megapolitana , some members of the B. cepacia complex , B. multivorans, B. tropica , B. thailandensis and B. contaminans [ 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 ]. Several B. gladioli strains show pathogenicity towards immunocompromised humans, plants, animals and inhibitory activity against fungi and other bacteria [ 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 ]. Genotypes of B. gladioli can also synthesize several molecules with different antagonistic mechanisms.…”

A random transposition mutant library of B. gladioli UAPS07070 was analyzed for searching mutants with impaired microbial antagonism. Three derivates showed diminished antimicrobial activity against a sensitive strain. The mutated loci showed high similarity to the quorum sensing genes of the AHL-synthase and its regulator. Another mutant was affected in a gene coding for a LysrR-type transcriptional regulator. The production of toxoflavin, the most well known antimicrobial-molecule and a major virulence factor of plant-pathogenic B. glumae and B. gladioli was explored. The absence of a yellowish pigment related to toxoflavin and the undetectable transcription of toxA in the mutants indicated the participation of the QS system and of the LysR-type transcriptional regulator in the regulation of toxoflavin. Additionally, those genes were found to be related to the swarming phenotype. Lettuce inoculated with the AHL synthase and the lysR mutants showed less severe symptoms. We present evidence of the participation of both, the quorum sensing and for the first time, of a LysR-type transcriptional regulator in antibiosis and swarming phenotype in a strain of B. gladioli
