A large amount of antibiotics has long been used to control pathogenic diseases and as growth promoters to improve performance in livestock. However, this approach had significant and unwanted side-effects, such as development of antimicrobial resistance and carry-over of the antibiotic residues to poultry products. In this light, the use of antibiotics as growth promoters (AGPs) was banned by ...
Cells containing reporters which are specifically induced via selected promoters are used in pharmaceutical drug discovery and in environmental biology. They are used in screening for novel drug candidates and in the detection of bioactive compounds in environmental samples. In this study, we generated and validated a set of five Bacillus subtilis promoters fused to the firefly luciferase repor...
The desirable features for a screening assay to detect antibacterial antibiotics include 1) high specificity for the desired antibiotic type 2) high sensitivity 3) lack of interference by other compounds likely to be associated with the antibiotic of interest and 4) ease of operation to allow a large number of samples to be tested. These characteristics are largely found in screens employing st...
Currently, the high food demand led to a mass agriculture practices, whereas crop productivity is one of major concerns for producers. However, intensification use synthetic fertilizers has serious harmful impacts human health and environment. The quest novel natural agricultural products current trend, hence seaweed polysaccharide bioactivity can contribute this pursuit. principal carbohydrate...
