We consider a mathematical model for a bacterial growth in a Petri dish. The model consists of partial dieren tial equations and a hysteresis operator describing the relationship between some variables of the equations. We consider the hysteresis relation to be represented by a completed relay ...

Bacterial culture is a very important research method in medical treatment, animal husbandry, agriculture and forestry. Bacterial culture inevitably requires counting the number of bacteria. However, the commonly used counting method is very time-consuming and labor-intensive, and there are errors, and...
Bacteria are commonly grown on petri dishes containing a growth medium filled with nutrients needed for bacterial survival.Answer and Explanation: This statement is false. A quadrant streak is used to spread bacteria onto a petri dish through four successive "streaks." Each streak....
Clinical microbiology automation is currently limited by the lack of an in-plate culture identification system. Using an inexpensive, printed, disposable colorimetric sensor array (CSA) responsive to the volatiles emitted into plate headspace by microorganisms during growth, we report here that not only...
In addition to low-cost BC products, BC with different properties must be modified for various applications. In particular, BC, when used as a scaffold material in tissue engineering, is often enriched with various growth factors to stimulate or regulate the differentiation of specific tissues. BC...
Bacterial volatiles promote plant growth and elicit immunity responses in plants grown in two-compartment Petri dishes. Due to the limitations of bacterial volatile compound (BVC) treatments such as their high evaporation rates, it is convenient to apply BVCs in closed systems such as greenhouses....
(E,F) The growth and morphological characteristics of the biocontrol agent S. maltophilia on the nutrient agar medium from the top and the bottom of the Petri dish, respectively, after 7 days of incubation at 28 ± 2 °C. (G) The evolutionary analysis with the Maximum Likelihood method ...
Xanthomonas euvesicatoriais a bacterial phytopathogen and a cosmopolitan causal agent of pepper bacterial spot in countries with continental, tropical, and subtropical climate. Crop losses are usually very severe if the infection occurs at an early growth stage [1]. Defoliation as an infection conseque...
