Chapter 46, Problem 3CT
Nitrogen-fixing bacteria live throughout the ocean, from its sunlit upper waters to 200 meters (650 Feet) beneath its surface. Recall that nitrogen is a limiting factor in many habitats. What effect would an increase in populations of marine nitrogen-fixers have on carbon uptake and primary productivity in those waters?

Soil microorganisms, collectively referred to as dizotrophs, fix 90% of the inert nitrogen gas to
ammonium and nitrate. There are two-main types of nitrogen-fixing bacteria: free-living (nonsymbiotic)
and mutualistic (symbiotic). Describe the mutualistic relationship between Rhizobium and legumes. What
is the advantage of using legumes as a cover crop in agricultural systems?
A point of interest is that the nitrogenase enzyme complex is highly sensitive to oxygen. This is a major
problem for free-living aerobic species such as cyanobacteria and species of the genera Azotobacter and
Beiigrinckia. Describe two ways the bacteria can overcome to levels of oxygen in their cells.
Nitrogen fixing organisms have unique problems in terms of energy production and the need for low O2 tension to protect nitrogenase. Describe in detail how Azotobacter and Rhizobium species solve these problems. Thank you
Given that the bottom of the ocean is anaerobic, what process in the nitrogen cycle is likely to be occurring in this location?

(Economic applications?)arrow_forwardRegarding nitrogen fixation, are the following statements True or False? a) Atmospheric nitrogen is reduced to the biologically useful form NH3 (or NH4 ). b) Nitrogen fixation in nature and in the lab requires a metal cofactor or catalyst. c) The availability of fixed nitrogen limits biological productivity. d) Ammonium from the atmosphere is fixed to more usable forms of nitrogen, such as nitrite (NO2–). e) Nitrogen fixation is energetically neutral, using a negligible amount of ATP. f) The enzyme nitrogenase, which takes part in nitrogen fixation, is inactivated by oxygen.arrow_forwardAntibiotics enter the environment in wastewater from pharmaceutical manufacturing plants, in wastes from farms where they are used in animals, and in sewage from human populations. (Many antibiotics are excreted in their active form.) The influx of antibiotics into the environment is a concern because the presence of these compounds in the environment selects for antibiotic resistance. As pollutants, antibiotics can also have ecological effects. Describe some of the ecological roles of bacteria, and explain why disruption of these roles by antibiotic pollution would have a negative impact.arrow_forward

There are many places in the Philippines, which are now contaminated by petrochemical sources, such as petroleum refineries and storage sites, paint manufacturing plants, gasoline service stations, gas emissions, etc. (EMB-DENR, 1997). Although the basic solution to the pollution problem is the elimination of the sources of these pollutants, there are however overriding economic, social and political factors that must be considered. An attractive remedial measure is the use of pesticide-degrading microorganisms for the environmental clean-up. Bacteria of the genus Bacillus are a group of versatile microbes known to degrade complex organic matters refractive to most microorganisms. Several species produce enzymes that catalyze the breakdown of petroleum products in water as well as in oil. These bacteria may provide the means of eliminating unwanted pollutants in the…arrow_forwardWhat are the unique problems associated with Nitrogen fixing organisms in terms of energy production and the need for low O2 tension to protect nitrogenase?
