Streptomyces bio-products against apple and pear diseases in organic orchards

Tinatin DOOLOTKELDİEVA

Erwinia amylovora as a fire blight pathogen and Venturia inaequalis as a scab pathogen were isolated from the blossoms, exudates, infected fruits, leaves and bent branches of diseased apple, pear and hawthorn trees, selected in the Chy, Osh and Jalal Abad regions. Biochemical and pathogenicity tests, alongside PCR analyses were conducted to identify the local isolates of Erwinia amylovora and Venturia inaequalis. The alternative antagonistic microorganisms which combat bacterium E. amylovora and fungus Venturia inaequalis were tested within in vitro and in vivo conditions. The results revealed ...Более

Mürüvvet ILGIN

In this study, Abbas fig variety grown in Kahramanmaraş province of Turkey was used.Abbas fig variety was covered with peppermint oil, an essential oil variety, and stored at 4°C for 5 weeks in bags prepared with modified atmosphere packaging (MAP) technology. As a result of the study, it was aimed to extend the storage time and shelf life of the fig fruit with these applications. Pomological and chemical analyses were performed on the samples during storage.In the study, in order to determine fruit quality characteristics, weight loss, fruit width and fruit length, fruit rind and flesh color, ...Более

Tinatin DOOLOTKELDİEVA

The main agricultural activities in the Kyrgyz Republic are include the production of cereal grains, vegetables, potatoes and commercial crops such as cotton, tobacco, sugar beets and livestock. The sustainability of the agriculture sector was severely affected by the large scale mono-cropping approach of the Soviet era. Intensive agriculture has caused environmental pollution due to the excessive use of mineral fertilizers and pesticides. To combat this menace we have isolated and introduced non-chemical crop protection agents, the antifungal micro-organisms Streptomyces spp., producing antib ...Более

Alkane monooxygenase diversity recovered from Central Asia sediments

Tinatin DOOLOTKELDİEVA

Previous studies in our lab and elsewhere showed that different microbial gene groups are obtained from geographically distant sites. Alkane monooxygenases activate terminal carbon-carbon bonds in the first step of alkane degradation with the addition of an oxygen to the compound, resulting in an alcohol product. The aim of this study was to test the hypothesis that unique microbial populations and alkane monooxygenase (alkB and Cytochrome P450) genes can be recovered from geographically distinct sites, with varying degrees of anthropogenic impact. Sediment was collected from six river and str ...Более
