Bacterial Growth and Productivity

Earlier discussions emphasized that dead organic matter, called detritus, exists as a spectrum from dissolved organic compounds, organic colloids, and larger particles of organic matter. Dissolved organic matter is in much greater abundance, by about five to ten times, than is particulate organic matter. All microflora must degrade particulate organic matter enzymatically to the dissolved form prior to assimilation for further metabolic breakdown and eventual mineralization to inorganic solutes and gases.
