Biological indicators commonly use the microorganism Geobacillus stearothermophilus. This bacterium is highly resistant to heat and serves as a reliable test organism for validating sterilization processes, particularly in steam sterilization. Its spores are used to confirm that sterilization conditions have been effectively met. When subjected to proper sterilization, the spores should be killed, indicating the process's efficacy.
Indicators are used frequently for testing pH; but many other indicators exist for other compounds or ions.

Biosensors are commonly used for the collection and detection of biological agents. They can detect specific biological molecules, such as proteins or DNA, through a combination of biological recognition elements and transducers that convert the biological response into a measurable signal. These devices are widely used in fields such as healthcare, environmental monitoring, and food safety.
Biological safety cabinets are used for handling biological agents safely by providing a contained workspace with controlled airflow. Biosensors are used for detecting and measuring biological agents in samples by converting a biological response into an electrical signal. Polymerase chain reaction (PCR) machines are used to amplify and detect DNA or RNA of biological agents for identification and analysis.
Performance indicators used in ports typically include metrics such as vessel turnaround time, berth occupancy rate, cargo handling productivity, container dwell time, and equipment utilization. These indicators help measure the efficiency and effectiveness of port operations and identify areas for improvement.
Biological indicators are species used to monitor the health of an environment or ecosystem.
Toxins
Biological indicators of water pollution are organisms or biological communities that reflect the health of aquatic ecosystems and the quality of water. Common indicators include macroinvertebrates, such as mayflies and caddisflies, which are sensitive to pollution and can indicate changes in water quality. The presence, absence, or abundance of certain species can help assess levels of organic matter, toxic substances, and overall ecological balance in a water body. Monitoring these indicators is essential for effective water quality management and pollution control.

Pollution indicators can include changes in air quality, such as high levels of particulate matter or ozone. Water pollution indicators may involve elevated levels of contaminants like heavy metals or bacteria. Biological indicators like the presence of certain species can also signal pollution in an ecosystem.
There are two main types of indicators used in titration: color indicators and pH indicators. Color indicators change color at specific pH ranges to indicate the endpoint of the titration, while pH indicators change color based on the pH of the solution.
Autoclaves can be tested for proper functioning using biological indicators, chemical indicators, and physical monitoring. Biological indicators involve using specific spores that are resistant to sterilization; if the spores are killed after the autoclave cycle, it confirms effective sterilization. Chemical indicators change color when exposed to specific conditions of temperature and pressure, providing a quick visual check. Additionally, physical monitoring includes checking temperature and pressure readings on the autoclave's gauges during operation.
