The significance, however, is in the relative rates of such processes, such as days, weeks, years or centuries.

A number of factors determine the rate at which this degradation of organic compounds occurs.

The breakdown of materials by microorganisms when oxygen is present, it's aerobic digestion.

And the breakdown of materials when oxygen is not present, is anaerobic digestion.Several materials will test as being biodegradable under optimal conditions in a lab for approval but these results may not reflect real world outcomes where factors are more variable.For example, a material may have tested as biodegrading at a high rate in the lab may not degrade at a high rate in a landfill because landfills often lack light, water, and microbial activity that are necessary for degradation to occur.Some of the products from fragmentation are easily transported within the cell by membrane carriers.However, others still have to undergo biotransformation reactions to yield products that can then be transported inside the cell.A prominent example is poly-3-hydroxybutyrate, the renewably derived polylactic acid, and the synthetic polycaprolactone.Others are the cellulose-based cellulose acetate and celluloid (cellulose nitrate).This site uses cookies to improve performance by remembering that you are logged in when you go from page to page.To provide access without cookies would require the site to create a new session for every page you visit, which slows the system down to an unacceptable level.
