pantoea ananatis is an important pathogen causing bacterial center rot in onion. isolated strains from onion soft rot bulbs based on morphological characteristics were tested for hypersensitivity reaction on tobacco. pathogenic strains underwent some biochemical tests which detected the presence of p. ananatis, based on rna16s sequencing, this result was confirmed. symptoms were reproduced by i...

We studied bacterial isolates 15M and 16M from calla lily tubers showing soft rot in commercial plantations in Poland. Colony morphology differed from that of known agents of bacterial soft rot of this plant. The use of Microgen Bacillus ID system allowed to identify both isolates as Paenibacillus polymyxa. This was confirmed by sequence analysis of 16S rRNA gene fragments. The isolates showed ...

Bacterial diseases of bananas and enset have not received, until recently, an equal amount of attention compared to other major threats to banana production such as the fungal diseases black leaf streak (Mycosphaerella fijiensis) and Fusarium wilt (Fusarium oxysporum f. sp. cubense). However, bacteria cause significant impacts on bananas globally and management practices are not always well kno...

BACKGROUND Understanding about the impact of white rot fungi on indigenous bacterial communities, NH4+ and turbidity in digested piggery wastewater, will allow the optimization of wastewater treatment methods and its use as a feasible medium for algal growth. Here, the white rot fungi were inoculated into undiluted and unsterilized digested piggery wastewater under different temperatures and pH...

The internal stipe necrosis of cultivated mushrooms (Agaricus bisporus) is caused by the bacterium Ewingella americana, a species of the Enterobacteriaceae. Recently, Ewingella americana was isolated from cultivated white button mushrooms in Korea evidencing symptoms of internal stipe browning. Its symptoms are visible only at harvest, and appear as a variable browning reaction in the center of...

Mutations in rot restore in vitro toxin production to agr-negative strains of Staphylococcus aureus. We show that a rot mutation returns wild-type virulence to an agr mutant, as measured in experimental endocarditis infections by target organ bacterial counts. Implications of our data are discussed in terms of agr antagonist strategies.

Rhizo-bacteria of high biocontrol potential against different Fusarium isolates were bio-assayed under both laboratory and greenhouse conditions. Eighty five rhizo-bacteria isolated from the rhizosphere of plants growing in various desert areas were screened for their antagonistic activity against eight Fusarium isolates (four isolates of Fusarium solani and four isolates of Fusarium oxysporum)...

samples with stalk rot, yellowing and stunting symptoms from maize fields in western provinces of iran were collected. after cultured of them on eosin methylen blue (emb) medium, twenty bacterial strains with metallic green color colonies on emb medium were selected for identification tests. according to the biochemical and phenotypic characteristics, these strains were identified as dickeya ze...

Bacteria have been isolated from 10 different strains of Phanerochaete chrysosporium, a white rot fungus which degrades lignocellulosic materials. The investigations showed that one or more bacterial species were always associated with the fungus. Various attempts to eliminate the bacteria on the fungus were unsuccessful. Three different bacterial species were isolated and identified. One of th...

Soft rot caused by Pectobacterium carotovorum is one of most common bacterial diseases occurring in fruits and vegetables worldwide, yet consumer-acceptable options for post-harvest disease management are still insufficient. We evaluated the effect of potassium tetraborate tetrahydrate (B4K2O7.4H2O) (PTB) on the growth of P. carotovorum using strain BA17 as a representative of high virulence. C...
