Sure, here is a step-by-step guide on how to investigate the effects of antibacterial agents and antibiotics on the growth of bacterial culture:

1. **Preparation of Bacterial Culture**: Start by preparing a bacterial culture. This can be done by inoculating a sterile broth with the bacteria you wish to study. Allow the bacteria to grow until it reaches the log phase of growth.

2. **Preparation of Antibacterial Agents and Antibiotics**: Prepare different concentrations of the antibacterial agents and antibiotics you wish to test. This can be done by diluting them in a sterile solution.

3. **Inoculation**: Inoculate each concentration of the antibacterial agent or antibiotic into a separate culture of bacteria. Also, prepare a control culture without any antibacterial agent or antibiotic.

4. **Incubation**: Incubate the cultures at an appropriate temperature for the bacteria to grow. This is usually at 37 degrees Celsius for most bacteria.

5. **Observation**: After a suitable period of incubation, observe the cultures. Look for changes in the turbidity of the culture, which indicates bacterial growth. The more turbid the culture, the more bacteria are present.

6. **Measurement**: Measure the bacterial growth in each culture using a spectrophotometer. This device measures the amount of light that passes through the culture, which is inversely proportional to the amount of bacterial growth.

7. **Analysis**: Analyze the results. Compare the growth of bacteria in the cultures with the antibacterial agents or antibiotics to the growth in the control culture. This will give you an idea of the effectiveness of each antibacterial agent or antibiotic.

8. **Conclusion**: Draw conclusions from your results. Determine which antibacterial agents or antibiotics are most effective at inhibiting bacterial growth.

Remember to always follow lab safety procedures when handling bacteria and potentially harmful substances.
