Summary Introduction

To review:

The way by which ruminant fermentation provides food molecules that can be utilized by the animal host and the ability of the host to utilize the waste products formed by microbial metabolism.

Introduction:

An anaerobic process that leads to the breakdown of complex organic molecules into their simpler forms by the action of anaerobic microbes is referred to as fermentation. The rumen of the animals also possesses several anaerobic microbes that ferment the ingested food. The colon region of the large intestine of human beings is also referred to as a fermenter.

A) Filter-feeder B) Incomplete digestion C) Food vacuoles D) Extracellular digestion E) Substrate feeder 11. Organisms that have one opening for both entry of food and exit of undigested food. 12. Vacuole which contains foreign substances that fuses with lysosome which is involved with cellular digestion. 13. Clams suck in water to strain small organisms and dissolved nutrients found in water. 14. Larvae that thrive on the source of its food such as fly larvae staying on meat surface. 15. Mushrooms excrete enzymes within its surrounding where digestive cells and nutrients are transferred back through body fluid.
Assume tu inoculated 100 facultative anaerobic cells unto nutrient agar and incubated the plate aerobically. You then inoculated 100 cells of the same species unto nutrient agar and incubated the second plate anaerobically. After incubation for 24 hours, you should theoretically have: A) More coloneis on the aerobic plate B) More colories on the anaerobic plate C) The same number of colonies on both paltes D) Fewer colonies on the anaerobic plate E) None of the above
