Yes, agar agar can expire. To determine if it is still safe to use, check the expiration date on the packaging. Additionally, inspect the agar agar for any signs of discoloration, unusual odor, or mold growth. If any of these are present, it is best to discard the agar agar to avoid any potential health risks.
Agar-agar is a vegetarian substitute for gelatin made from seaweed. It is commonly used in cooking and baking to thicken, stabilize, or set foods such as desserts, soups, and jams. Agar-agar is flavorless, odorless, and has stronger gelling properties than traditional animal-based gelatin.

Agar is generally made by mixing the powdered form with varying ingredients. The powder is based on seaweed extract for nutrient agar, and nutrient agar is generally a base for most other agars - eg. Horse Blood Agar is nutrient agar with horses blood added; Choc agar has defibrinated (cooked) horses blood added.
The scientist who studied how wounds heal was Alexander Fleming, a Scottish scientist famous for his discovery of penicillin in 1928. He observed the antibiotic properties of the Penicillium mold on his petri dishes, leading to the development of the first antibiotic.

A scientist cannot be made responsible for his discoveries anymore than an explorer can be made responsible for his discoveries. In both cases the thing discovered was always there, it just needed someone to find it. Also if that scientist or explorer chose to withhold his/her discovery for fear of what might come of it, there is nothing to keep another person from discovering it too.
The scientists responsible for the discovery of bacterial transformation are Oswald Avery, Colin MacLeod, and Maclyn McCarty. They demonstrated that DNA is the genetic material that carries hereditary information in bacteria.
Agar, a type of polysaccharide derived from seaweed, solidifies nutrient agar plates when it cools below 45°C. This process forms a gel matrix that helps to support bacterial growth on the surface of the plate.

A detailed answer to the question can be found in John Forge's book The Responsible Scientist.
Because no scientific work is considered a "discovery" until it has been independently verified by several other scientists in different places. If their work verifies the original claim, then it is indeed, a "discovery" by the first scientist in question. If the work of the other scientists cannot verify it, or vary wildly from the first scientist's work, then it is not a new "discovery".
Who was the scientist who first suggested that the bacteria are responsible for many diseases of humans and animals
One scientist who does study heredity is called a Geneticist.
