Bacteria are variously shaped spherical (cocci), rod-shaped (bacilli), spiral shaped (spirilla) and vibrio (comma-shaped). The microorganisms help keep nutrients cycling through the ecosystem. What are Bacteria. Microorganisms play a primary role in regulating biogeochemical systems in virtually all of our planet 's environments. 2. In other words, bioremediation is a procedure for the eradication of environmental pollutants from the ecosystem through the application of microbes to restore the ecosystem to its original form (Ayangbenro and Babalola, 2017). There is an urgent need for sustainable techniques to address this problem to generate a minimal impact on the environment. Soil microbes are a dynamic component of soil and performed many beneficial functions in the soil system. At onset there are usually no symptoms, but if they develop, symptoms generally begin around middle age. In their natural environment, plants are part of a rich ecosystem including numerous and diverse microorganisms in the soil. Bacteria are single-celled organisms, which means that the basic structure of the bacteria is simple and easy to distinguish under a microscope.
