Microarray analysis of high light intensity stress on hydrogen production metabolism of Rhodobacter capsulatus
Gurgan, Muazzez; Koku, Harun; EROĞLU, İNCİ; Yucel, Meral (Elsevier BV, 2020-01-29)
Biohydrogen obtained from purple non sulfur bacteria (PNSB) is an environmentally friendly alternative for hydrogen production. PNSB can be employed in large scale outdoor photobioreactors to produce hydrogen by photofermentation with sunlight as the light source. In external environmental conditions, however, bacteria can experience stress due to high light intensities, which can inhibit or slow down hydrogen production. Previous studies with other PNSB showed varying responses to light intensities (above ...
Microarray analysis of the effects of light intensity on hydrogen production metabolism of rhodobacter capsulatus

Biohydrogen generated by purple non-sulfur bacteria is a clean and renewable method of hydrogen production. It can be achieved in outdoor phototobioreactors using the natural sun light in lab to pilot scales. Light is one of the most important parameter affecting hydrogen production in the outdoor condition. Hydrogen productivity may decrease upon light intensity stress by sun light and the diurnal cycle in outdoor conditions. It is important to understand the metabolic response of these bacteria to varying...
Microarray analysis of the effects of heat and cold stress on hydrogen production metabolism of Rhodobacter capsulatus

Rhodobacter capsulatus DSM1710 is a purple non-sulfur bacterium capable of hydrogen production via photofermentation. Biohydrogen is a clean and renewable way of hydrogen production, which can be achieved by PNS bacteria in outdoor large scale photobioreactors using sun light. In outdoor conditions bacteria can be exposed to heat and cold stress. In this study in order to understand the effects of heat and cold stress on photofermentative hydrogen production and gene expression profile of R.capsulatus on ac...

DNA microarrays, being high-density and high-throughput, allow quantitative analyses of thousands of genes and their expression patterns in parallel. In this study, Barley1 GereChip was used to investigate transcriptome changes associated with boron (B) toxicity in a sensitive barley cultivar (Hordeum vulgare L. cv. Hamidye). Eight-day-old aseptically grown seedlings were subjected to 5 or 10 mM boric acid (B(OH)(3)) treatments for 5 days and expression profiles were determined with DNA microarrays using to...
Microarray based expression profiling of barley under boron stress and cloning of 3H boron tolerance gene
Öz, Mehmet Tufan; Eyidoğan, Füsun; Öktem, Hüseyin Avni; Department of Biotechnology (2012)
Both deficiency and toxicity of the essential micronutrient boron (B) lead to reduced crop yield in agriculture. However, our understanding of the molecular responses of plants under B stresses to tackle the yield loss is limited. Therefore, in the present study, transcriptional alterations in sensitive and tolerant barley cultivars under B deficiency and toxicity were investigated in order to reveal the molecular responses. Transcriptomes were monitored at seedling stage by global expression profiling usin...
