Due to the increase of microbial resistance to antibiotics and the occurrence of side effects, use of medicinal plants with anti-microbial properties seems to be rational. Hence, in this study, some plants of the Apiaceae, Asteraceae, Brassicaceae, and Cucurbitaceae families were evaluated for antimicrobial effects. The aerial parts of the plants were extracted by different solvents using a Sox...
Microorganisms are vital in mediating the earth's biogeochemical cycles; yet, despite our rapidly increasing ability to explore complex environmental microbial communities, the relationship between microbial community structure and ecosystem processes remains poorly understood. Here, we address a fundamental and unanswered question in microbial ecology: 'When do we need to understand microbial ...

background and objectives: pre-requisite programs (prps) are “primary conditions and requirements essential for haccp operations, which are crucial in food safety programs”. the present study was conducted to evaluate the impact of implementation of prps on the microbial parameters of pasteurized milk (according to the national standard of iran). effectiveness of haccp operation requirements an...
Motivation: Microbial communities play important roles in the function and maintenance of various biosystems, ranging from human body to the environment. Current methods for analysis of microbial communities are typically based on taxonomic phylogenetic alignment using 16S rRNA metagenomic or Whole Genome Sequencing data. In typical characterizations of microbial communities, studies deal with ...
Functional gene markers can provide important information about functional gene diversity and potential activity of microbial communities. Although microarray technology has been successfully applied to study gene expression for pure cultures, simple, and artificial microbial communities, adapting such a technology to analyze complex microbial communities still presents a lot of challenges in t...
Proteomics has begun to provide insight into the biology of microorganisms. The combination of proteomics with genetics, molecular biology, protein biochemistry and biophysics is particularly powerful, resulting in novel methods to analyse complex protein mixtures. Emerging proteomic technologies promise to increase the throughput of protein identifications from complex mixtures and allow for t...
We are interested in quantitative understanding of the design and functioning of cellular networks. Although specific molecular mechanisms differ, any such system must be able to extract signals from a noisy environment, adapt to large changes in signal and background strengths, and integrate multiple cues. It can thus be expected that biological networks rely on a small number of common evolut...
The set of proteins which are conserved across families of microbes contain important targets of new anti-microbial agents. We have developed a simple and efficient computational tool which determines concordances of putative gene products that show sets of proteins conserved across one set of user specified genomes and not present in another set of user specified genomes. The thresholds and th...
