Antibiotic screens typically rely on growth inhibition to characterize compound bioactivity-an approach that cannot be used to assess the bactericidal activity of antibiotics against bacteria in drug-tolerant states. To address this limitation, we developed a multiplexed assay that uses metabolism-sensitive staining to report on the killing of ...
Some examples of primary screening criteria are hydrolysis halos, inhibition halos, precipitation or emulsification halos, pH indicator changes, growth in solid …
Quantification of Antibiofilm activity. All Actinomycetes crude extracts showed both biofilm inhibition and destruction activity against B. cereus, B. subtilis, and S. putrefaciens.The inhibition activity of biofilms formed by the food spoilage bacteria can be seen in Table 3, where biofilms formed by B. cereus and S. putrefaciens inhibited the …
Tomato yield losses are mainly caused due to bacterial wilt (Ralstonia solanacearum) throughout the world. The disease management is mainly done through chemicals which lead to health risks. Among non-chemical strategies, development of resistant varieties can be a good alternative. The present study was conducted to screen …
A series of linear pentamidine analogs exhibiting low cytotoxicity, active against Pneumocystis carinii, were evaluated for in vitro activities against bacterial and fungal strains. The majority of the tested bis-amidines exhibited marked activities against Gram-positive strains. In view of the fact that the highest potency was found for 1,5 ...

These bacteria produce several secondary metabolites including antimicrobial compounds. The objectives of this study were to isolate and identify EPNs and their symbiotic bacteria from Mae Wong National Park, Thailand and to evaluate the antibacterial activities of symbiont extracts against drug resistant bacteria.
Bacterial leaf blight (BLB) is one of major threats in rice production as it can cause yield loss. Concern on the environment and human health has led an attempt to replace existing methods of chemical control and avoid extensive use of bactericides by using endophytic bacteria. The present study was conducted to screen and characterize …
Rice blast is an important disease but effective biological control agents (BCAs) for controlling the causal organism Magnaporthe grisea, are currently unavailable.In this study, to effectively screen potential BCAs against M. grisea from those substrates, an assessment system was established to screen the biological control potential from 935 …
A total of 98 isolates with antagonistic activity against Phytophthora capsici were isolated from the rhizosphere soil of healthy pepper plants in the fields seriously infected by pepper Phytophthora capsicit, and two strains named as HL-3 and LZ-8 were screened, which had the characteristics of wide-spectrum antagonism and good growth under poor soil …
Walnut blight caused by Xanthomonas arboricola pv.juglandis (Xaj) is the most important bacterial disease in walnut production worldwide.To seek biocontrol agents against Xaj, we screened 152 endophytic bacteria isolated from 87 plants.Through dual-culture method screening, we obtained four antagonistic bacteria, ATE17, BME17, CIE17, and OFE17 …
