Lactococcus lactis

Description and significance
Pseudomonas putida are Gram-negative rod-shaped bacteria. They are classified as Group 1 in Pseudomona. Other Pseudomonads are being re-evaluated to see if they truly fall into this category, while P. putida is firmly place in this group. P. putida are flourescent, aerobic, non sporeforming, oxidase positive bacteria. Having one or more polar flagella, they are motile organisms. They can be found in moist environments, such as soil and water, and grow optimally at room temperature. Certain strains have the ability to grow on and break down many dangerous pollutants and aromatic hydrocarbons such as toluene, benzene, and ethylbenzene. P. putida can also be used in petroleum plants to purify fuel. This bacterium is also capable of promoting plant growth after root colonization as well as simultaneously providing protection for the plant from pests and other harmful bacteria.
