These bacteria include the following species: Gluconobacter oxydans, Acetobacter aceti, and Erwinia herbicola. Erwinia herbicola is a member of the Enterobacteriaceae, a family that contains certain known plant pathogens in the genus Brenneria, Erwinia, and Pantoea. In the last few years, Pantoea citrea has been described as the causative agent of pink disease. It could be something soaked up into the fruit by the soil of the tree it grew on? Lapage, S.

The pink disease of pineapple, caused by the bacterium Pantoea citrea, is characterized by a dark coloration on fruit slices after canning. They were Gram-negative rods, produced acetic acid from ethanol, oxidized acetate and lactate to CO(2) and H(2)O, and had Q-9 as the major ubiquinone system. demonstrated high sequence similarities (99.6 to 94.2%, corresponding to 7 to 83 base differences). However, full pink coloration development, which is characteristic of the pink disease, appears to require this plasmid. Attem, member of the alpha-proteobacteria) and En, member of the beta-proteobacteria). Nutrition of Acetobacter species.—Arch. These organisms have been characterized with regard to their nutritional requirements and optimal growth properties (4), and are classified in distinct families: Acetobacteriaceae (as a member of the alpha-proteobacteria) and Enterobacteriaceae (as a member of the beta-proteobacteria). In this paper it has been shown that P. citrea contains a second, homologous gdh gene and its product, GdhB, represents the main source of Gdh activity in this organism. 23: 283–286. These isolates exhibited typical pathogenicity reactions in pineapple juice tests, pineapple slices and fruit. ananas. Cho, J. J., Hayward, A. C., and Rohrbach, K. G. 1980. symptomatology of pink disase of pineapple fruit in the Philippines. Erwinia herbicola is a member of the Enterobacteriaceae, a family that contains certain known plant pathogens in the genus Brenneria, Erwinia, and Pantoea.

J. and Douderoff, M. 1966. A previously isolated chemical mutant, CMC6, which is deficient in Gdh activity and pink disease formation, failed to express gdhB during the stationary phase of growth. All investigated species had unique 16S rDNA sequences by, Indirect immunofluorescence tests with antisera against whole cells of Phenylobacterium immobile strains revealed a serological relationship to Pseudomonas vesicularis, Aquaspirillum itersonii and Rhodospirillum rubrum, three members of the purple nonsulfur bacteria (group I) and also to Gluconobacter oxydans and Azotobacter vinelandii. Plant genetic engineering strategies are also being considered. In affected fruit populations around 106 CFU/g of fresh tissue were recovered.
On the basis of nucleotide and amino acid sequence analyses, pUCD5000 contains both replication and mobilization loci (bom and mobCABD) that are similar to those in plasmids pSW100 and pSW200 in Pantoea stewartii and pEC3 in Erwinia carotovora subsp. parasitica

Erwinia herbicola Gluconobacter oxydans. Management of pests and diseases often are achieved through simple good agricultural practices that include destruction of crop residue, use of high quality planting material, proper cultivar selection, adjustments to soil pH, and good soil drainage. Rainbow, C. and Mitson, G. W. 1953. Our results show that, while the Tris-NaCl-EDTA-lysozyme system (pH 8.3) worked very well with bacterial strains of Gluconobacter oxydans (ATCC9937) and Acetobacter melanogenus (NCIM2259), the Tris-sucrose-EDTA-lysozyme system worked well for Erwinia herbicola (ATCC21998), Pseudomonas chlororaphis (NCIM2041) and Corynebacterium species (ATCC31090). IVth Int. Buddenhagen, I. W. and Dull, G. G. 1967. The pathogen responsible for causing pink disease remained obscure and the nature of the pink color formation of the pineapple fruit tissue was not understood.
No isolates were identified as A. aceti (Group I), A. peroxydans (Group III), and A. estunensis (Group VI). The diseases are sporadically distributed geographically, and the severity of diseases is different according to the latitude or weather. Erwinia ananas pv. De Ley, J. and Frateur, J. 31: 453–354.
