BACKGROUND Maize (Zea mays) is a C4 tropical cereal and its adaptation to temperate climates can be problematic due to low soil temperatures at early stages of establishment. METHODS In the current study we have firstly investigated the physiological response of twelve maize varieties, from a chilling condition adapted gene pool, to sub-optimal growth temperature during seedling emergence. To...
The continued spread of highly pathogenic H5N1 influenza viruses among poultry and wild birds, together with the emergence of drug-resistant variants and the possibility of human-to-human transmission, has spurred attempts to develop an effective vaccine. Inactivated subvirion or whole-virion H5N1 vaccines have shown promising immunogenicity in clinical trials, but their ability to elicit prote...
Microbial biofilms have great negative impacts on the world's economy and pose serious problems to industry, public health and medicine. The interest in the development of new approaches for the prevention and treatment of bacterial adhesion and biofilm formation has increased. Since, bacterial pathogens living in biofilm induce persistent chronic infections due to the resistance to antibiotics...
The cloning, overexpression and characterization of a cold-adapted DNA ligase from the Antarctic sea water bacterium Pseudoalteromonas haloplanktis are described. Protein sequence analysis revealed that the cold-adapted Ph DNA ligase shows a significant level of sequence similarity to other NAD+-dependent DNA ligases and contains several previously described sequence motifs. Also, a decreased l...
The ability to acclimate to variable environmental conditions affects the biogeographic range of species, their success at colonizing new habitats, and their likelihood of surviving rapid anthropogenic climate change. Here we compared responses to temperature acclimation (4 weeks at 7, 13 and 19°C) in gill tissue of the warm-adapted intertidal blue mussel Mytilus galloprovincialis, an invasive ...
BACKGROUND The biodiesel production can be carried out by transesterification using either chemical or enzymatic process. The enzymatic transesterification is more promising as it offers an environmental friendly option compared to the chemical process, where the lipases with high catalytic efficiency and good stability play a key role. Hence, it is of great value to identify novel lipases whic...
