摘要: Abstract Bacteria (dead and living) may be the main energy (food) source for benthic organisms — mainly because they are very nutritive in terms of proteins, carbohydrates, lipids, nucleic acids (phosphate-rich), ectocrine compounds. If methionine is an essential arnino acid organisms, then bacteria can supply this amino so that protein synthesis take place. A mechanism (substrate capture) by which obtain substrates a dilute environment presented.
