We constructed and characterized a transcriptional fusion that measures the availability of water to a bacterial cell. This fusion between the proU promoter from Escherichia coli and the reporter gene gfp was introduced into strains of E. coli, Pantoea agglomerans, and Pseudomonas syringae. The proU-gfp fusion in these bacterial biosensor strains responded in a quantitative manner to water depr...

Ascochyta blight, an infection caused by a complex of Ascochyta pinodes, Ascochyta pinodella, Ascochyta pisi, and/or Phoma koolunga, is a destructive disease in many field peas (Pisum sativum L.)-growing regions, and it causes significant losses in grain yield. To understand the composition of fungi associated with this disease in Zhejiang Province, China, a total of 65 single-pycnidiospore fun...

A bacterial consortium capable of degrading the linear alkylbenzene sulfonate (LAS) was isolated from the wastewater treatment plant. The bacterial consortium consisted of two members, Pantoea agglomerans and Serratia odorifera 2. Cells were grown evenly together in a minimal medium (M9) and nutrient broth (NB). The bacterial consortium was able to grow in the minimal medium containing LAS as t...

Xylella fastidiosa is a xylem-limited bacterium that causes citrus variegated chlorosis disease in sweet orange. There is evidence that X. fastidiosa interacts with endophytic bacteria present in the xylem of sweet orange, and that these interactions, particularly with Methylobacterium mesophilicum, may affect disease progress. However, these interactions cannot be evaluated in detail until eff...

Pantoea agglomerans strain E325, a commercially available antagonist for fire blight of apple and pear, was originally selected through screening based on suppression of Erwinia amylovora on flower stigmas, but specific mechanisms of antagonism were unknown. Bacterial modification of pH was evaluated as a possible mechanism by analyzing stigma exudates extracted from 'Gala' apple stigmas. The p...

Çalışmada; Kayseri Şeker’e ait Gemerek (Sivas) ve Yahyalı (Kayseri) şeker pancarı ekiliş alanlarında, bakteri içerikli mikrobiyal gübre formülasyonlarının pancar verimi kalitesi üzerine etkisi araştırılmıştır. Çalışmada “Beta marka Zanzibar (NZ) çeşidi çıplak tohum” tercih edilmiş 6 farklı izolatı (Pantoea agglomerans RK-79, Pantoea RK-92, Bacillus megaterium TV-3D, TV-6D, Paenibacillus polymyx...

Bu çalışma, in vitro ve vivo koşullarda farklı kaynaklardan izole edilen bakteri strainlerinin Erwinia amylovora’nın gelişimini engelleme potansiyellerini belirlemek amacıyla yapılmıştır. Patojen olarak Iğdır ilinde hastalık semptomu gösteren elma (Malus domestica L.) ağaçlarından 5 E. amylovora straini kullanılmıştır. In ortamda patojene karşı 130 test edilmiş bunlardan 34’ü etkili bulunmuştur...
