SAN FRANCISCO, Nov. 16 (Xinhua) -- Researchers of U.S. Stanford University have discovered new bacteria that were never seen before, which were described as "a dark matter of the biological world," said a study released Thursday. The two deep lineages of bacteria found in the dolphins' to...
Broiler carcasses were packed in low-permeability film bags that were evacuated, injected with CO2, then held at 2 C. Broilers were examined microbiologically and for off-odor to determine the shelf-life and types of bacteria. Vacuum level did not significantly affect bacterial counts. Broilers...
Well-known examples include species of Streptococcus and Staphylococcus. Rod-Shaped Bacteria Rod-shaped bacteria are also known as bacilli. As the name suggests, these species have a long, rod or stick-like shape. They are often found living in soil and water. Well-known examples of this ...
