Difference Between Bioaugmentation and Biostimulation

Biostimulation (meaning the addition of limiting nutrients to support microbial growth) and Bioaugmentation (meaning the addition of living cells capable of degradation) studies have enjoyed a heavy presence in literature and reviews of these technologies focusing on the technical aspects are very few if at all ...

What is the difference between biostimulation and bioaugmentation quizlet?

What is the difference between biostimulation and bioaugmentation? Biostimulation is a bioremediation process designed to remove pollutants from an environment. Bioaugmentation is a method used in laboratories to promote the growth of fastidious microbes.

What is bioremediation and bioaugmentation?

Bioaugmentation is a process where selected, standardized bacteria (microbes) are added to an area that has been contaminated with an unwanted substance. These bacteria breakdown the contaminants. ... Many of the most toxic environmental contaminants are now candidates for bioremediation.

What is the difference between Bioremediation and Biodegradation?

The key difference between biodegradation and bioremediation is that biodegradation is a natural process that occurs in the environment. On the other hand, bioremediation is an engineered technique applied by humans to clean the environment. ... Biodegradation is a microorganism-mediated decomposition of organic matter.

What is biostimulation used for?

While biostimulation is usually associated with remediation of hydrocarbon or high production volume chemical spills, it is also potentially useful for treatment of less frequently encountered contaminant spills, such as pesticides, particularly herbicides.

What is an example of Bioaugmentation?

An example of how bioaugmentation has improved an environment, is in the coke plant wastewater in China. ... In the enhanced microbial community indigenous microorganisms broke down the contaminants in the coke plant wastewater, such as pyridines, and phenolic compounds.

Is bacteria acidic or alkaline?

Most bacteria grow best around neutral pH values (6.5 - 7.0), but some thrive in very acid conditions and some can even tolerate a pH as low as 1.0. Such acid loving microbes are called acidophiles. Even though they can live in very acid environments, their internal pH is much closer to neutral values.

What are 2 types of bioremediation?

Some of the most common types of bioremediation are microbial bioremediation, phytoremediation, and mycoremediation.

What is bioremediation give an example?

Bioremediation companies that specialize in soil and groundwater use microbes that feed on the hazardous substances for energy, which results in the breakdown of the targeted contaminant. Examples include junkyards, industrial spills, land development, fertilizer use, and more.

What is Biosparging?

Biosparging is an in-situ remediation technology that uses indigenous microorganisms to biodegrade organic constituents in the saturated zone. In biosparging, air (or oxygen) and nutrients (if needed) are injected into the saturated zone to increase the biological activity of the indigenous microorganisms.

Which organism is most important in biodegradation?

Several microorganisms, including fungi, bacteria and yeasts are involved in biodegradation process. Algae and protozoa reports are scanty regarding their involvement in biodegradation [5]. Biodegradation processes vary greatly, but frequently the final product of the degradation is carbon dioxide [6].

What contaminants can be treated with bioremediation?

Contaminants treated using bioremediation include oil and other petroleum products, solvents, and pesticides. How Does It Work? Some types of microbes eat and digest contaminants, usually changing them into small amounts of water and harmless gases like carbon dioxide and ethene.

What are the types of Biodeterioration?

Types of Biodeterioration • 1. Physical or mechanical • 2. Fouling or soiling • 3. Chemical assimilator – using as food • 4.
