A video recording would be the best type of media to determine whether an organism is motile because it can capture the movement and behavior of the organism in real time, providing a more accurate assessment of its motility compared to images or text descriptions.
Microbiologists recommend inoculating a pair of oxidation-fermentation basal media without carbohydrates to determine the organism's ability to ferment specific carbohydrates. By comparing the results from both media types, microbiologists can differentiate between oxidative and fermentative metabolic pathways used by the organisms. This provides valuable information about the organism's metabolic capabilities.
An enriched medium
To reach an organism, you can use various methods such as calling them, sending an email, messaging through social media, or physically going to where they are located. The choice of communication method would depend on the preferred mode of contact of the organism and the urgency of the communication.
You can do an experiment to determine motility. You use a medium of agar that has tetrazolium salt (TTC). The TTC serves as a terminal electron acceptor for the bacteria and turns the medium red. You would inoculate a needle with your bacteria and put it straight into the media and straight out. After incubating your bacteria, if you see the red move away from where you inserted the needle, then it would indicate that your bacteria is motile. If the red is only in the place where you inserted the needle, then it is not motile.
Common media used to determine motility and growth patterns of bacteria include agar-based media such as nutrient agar, motility agar, or semisolid agar. These media allow for observing colony morphology, motility (through diffusion in semisolid agar), and growth patterns (e.g., pellicle formation). Additionally, specialized media like SIM (sulfide-indole-motility) agar can be used to detect hydrogen sulfide production, indole production, and motility of specific bacteria.

The two factors that determine media coverage of a campaign are: How candidates use their advertising budget and the "free" attention they get as news makers.
There is no information saying whether Nicole Brown Simpson was interested in the media.
I would think an aerobic organism would do the worst in an oxygen poor media, which would be one of the results of having an older media sitting around.
Semisolid media contains a 1.5% concentration of agar, which is used to grow and select isolated colonies. Semisolid media contains agar at a lower concentration (around 0.4%,) which is used for motility studies.
The media certainly are a source of information; whether any given viewer of the media can make sense of that information really depends upon the individual.
Comparing the growth of the four organisms in a given media allows you to understand their ability to thrive and survive under specific conditions, providing insights into their individual preferences and capabilities for growth. It can also help identify which organism is most adapted or suited to the particular media environment.
Knowing who created the text
You can determine whether culture media are sterile by checking for any signs of contamination such as unusual color, turbidity, growth, or foul odor in the media. Additionally, you can streak a small sample of the media onto an agar plate and incubate it to check for any microbial growth.
