Project description:A urease positive marine actinobacterium Brevibacterium lines was demonstrated to form and dissolve calcite precipitation in conditions with different concentration of Ca2+. Next-generation sequencing (NGS) was used to analyze the transcriptome of B. lines under 0, 50 and 150 mM Ca2+ after 24 h incubation to discover the differentially expressed genes involved. Results provide insight into the molecular response of B. lines stressed with different concentration of Ca2+.
Project description:Transcriptional profiling of ssa_1972-null mutant of Streptococcus sanguinis compared with wild type. The ssa_1972 gene was inactivated in Streptococcus sanguinis SK36 and transcriptional profile was compared with wild type SK36. More information can be found at http://www.people.vcu.edu/~pingxu
