Use of biotechnological approaches and processes to increase soil fertility productivity, allow be made sustainable agriculture with less use chemical fertilizers.So, the aim this study was understand biochemical mechanisms action 10 different plant growth promoting rhizobacteria (PGPR) species (Bacillus megaterium (M3), Pantoea agglomerans (RK-92), Bacillus (Tv-17C), (Tv-3D), (Tv-87A), Hafnia alvei (Tv-34A), (Tv-60D), Pseudomonas fluorescens (FDG-37), (KBA-10) (Tv-91C) on their host...

Abstract This study was carried out to identify pathogenic bacteria and fungi on mistletoe ( Viscum album L.) investigate their potential use in biological control of this parasitic plant. For purpose, a total 48 fungal isolate 193 bacterial strains were isolated from contaminated V. during the summers 2005–2006. The isolates identified by using Sherlock Microbial Identification System MIS ; ID , Newark) microscopic methods, respectively. that induced hypersensitive reaction HR ) tobacco...

Abstract This study was conducted for identifying phylogenetic relationships between 15 scab-causing Streptomyces species including S. bottropensis, europaeiscabiei , scabiei stelliscabiei and, other 11 sp. All of the strains were originally isolated from symptomatic potatoes in Erzurum Province, The Eastern Anatolia Region Turkey. Some morphological and biochemical properties defined our former research. Then, 16 s rRNA regions them sequenced. After sequence data assembly, analyzes...

ABSTRACT : The common bean ( Phaseolus vulgaris L.) belongs to the family Leguminosae, and is a diverse food resource of high nutritional value. Plant growth promoting bacteria (PGPB) are group that actively colonize plants, increase plant yield, suppres disease. In this study, effectiveness ten PGPBs Alcaligenes piechaudii strain RK-136, Bacillus megaterium M-3, pumilus M-13, subtilis BA-142, Erwinia rhapontici RK-135, Burkholderia cepacia RK-277, Pantoea agglomerans RK-84, RK-123, RK-92,...

In this study, five non-pathogenic Pantoea agglomerans strains were utilized. The objective of study was to test for biochemical characteristics these strains, and evaluate their inoculation effects on fruit set rate, pomological traits, chemical compositions some vegetative parameters plum cultivar 'Stanley'. results showed that the tested had beneficial composition and/or growth in comparison control. conclusion, (especially RK-85) are suitable inoculants cultivation cold areas such as...

In this study we aimed that isolation, identification and characterizations of PGPR strains from rhizosphere legume plants. 188 bacterial isolated different plants like clover, sainfoin vetch in Erzurum province Turkey. These three are cultivated commonly the province. It was screen 50 out can fix nitrogen solubilize phosphate. were identified via MIS (Microbial system). According to results, 40 as Bacillus, 5 Pseudomonas, 3 Paenibacillus, 1 Acinetobacter, Brevibacterium. classical test...

Emergence of multi-drug-resistant bacteria poses an imminent and clear threat to human health. Acinetobacter baumanii is such organism, which may cause up 40% mortality due bacteremia. Ranunculus kotschyi, a widespread herb, utilized in Türkiye for treatment rheumatism, leg pain bruises folk medicine, also consumed as food. Molecular identification kotschyi was performed using ITS1 partial sequence, 5.8S ITS2 sequence. Phylogenetic analyses the plant were conducted. The sample extracted...

β-Lactamases are enzymes that catalyze the hydrolysis of β-lactam ring, resulting in loss function antibiotics. In this report, inhibition β-lactamase enzyme by group-based selected aromatic compounds, especially containing flavone was investigated vitro and silico. For purpose, inhibitory effects 7-hydroxy-4'-nitroisoflavone, myricetin, formononetin, 3-methylflavone-8-carboxylic acid, 6-fluoroflavone caffeic acid on from Bacillus cereus activity were investigated. IC50 values these...

Like most cultivated crops, onions (Allium cepa L.) are plagued by phytopathogenic bacteria. Although bacterial diseases of onion occur sporadically, they can cause loss yield, in the range a few percent up to 40%. Center rot caused Pantoea ananatis is one major disease. Cultural methods and copper compounds often recommended for control diseases, but these insufficient use some chemicals has adverse effects. For reasons, biological important manner plant In this study; it was researched...

The aim of this study is to determine effect Origanum rotundifolium's essential oil on some plant pathogenic bacterias, seed germination and growth tomato. Xanthomonas axanopodis pv. vesicatoria strain (Xcv-761) Clavibacter michiganensis ssp. (Cmm) inoculated tomato seed. seeds were tested for in vitro disease severity parameters vivo. In assay, maximum was observed at 62,5 µl/ml treatment with Xcv-761 streptomycin Cmm. least infected cotiledon number 500 µg/ml vivo 250 teratment Lowest...

Bu calismada; bitki buyumesini tesvik eden bazi bakteriyel strainlerin (Pantoea agglomerans strain RK-79, RK-80 ve RK- 92, Serratia liquefaciens RK-102 Pseudomonas putida RK-142) arazi sartlarinda sekerpare kayisi cogurlerinin boyu, govde capi, yillik surgun sayisi, yaprak alani, yan kok sayisi capi uzerine etkilerinin arastirilmasi amaclanmistir. Butun strainler kontrole gore boyunda istatistiki olarak onemli artislara sebep olmustur. Uygulamalarin alanina etkisi ilk yik onemsiz bulunurken,...

OZET: Bu calismada; Erzurum, Erzincan, Artvin, Kars ve Igdir illerinde yumusak cekirdekli meyve agaclarindan izole edilen ates yanikligi hastaliginin etmeni Erwinia amylovora’nin toplam 41 straininin streptomisin sulfata karsi duyarliliklari test edilmis; mikrobial tani sistemi (MIS) ile strainlerin yag asidi metil ester (FAME) gruplari belirlenerek, patojenin asitleri antibiyotiklere arasindaki iliski arastirilmistir. Elde sonuclara gore % 31,7’sinde dayaniklilik tespit edilmistir. Yag...
