OF test is used to differentiate those organisms that utilize carbohydrates aerobically (Oxidation) such as P. aeruginosa, from those that utilize carbohydrates anaerobically (Fermentation) such as members of the Enterobacteriaaceae. The OF medium contains peptone, test carbohydrate and bromothymol blue as indicator. When carbohydrate is utilized, acids are formed which changes the colour of the medium from green to yellow
They break down dead biological matter and waste products and convert them into useable energy; returning important materials to the environment. Decomposers are a particular important feature in the Great Barrier Reef considering the heavy bio-load. Main decomposers inside the reef include bacteria, sea cucumbers, some species of snails, crabs and bristle worms. Bacteria sis not only vital for the Great Barrier Reef’s food web, but is also said by scientists that it could be the key to keeping the coral healthy and able to withstand the impacts of global warming. Dr Tracy Ainsworth stated “it is very likely that these microorganisms play a vital role in the capacity of coral to recovering from bouts of bleaching caused by rising temperatures.” Corals rely on these good bacteria’s crucially although we don’t yet understand these microbe’s ell enough to know how they influence coral survival, which is vital in maintaining the food web of the Great Barrier Reef.
Using the micropipette, we transferred the appropriate volume of algae to the jars. We collected a sample of brine shrimp and added them to petri dishes in order to view them underneath a dissection microscope. Because we were testing the top-down effects, we decided on having
Biodiesel is produced from vegetable oils, used cooking oils, and animal fats by the production process called “trans-esterification” to convert those mixtures to the chemicals which have long chain mono alkyl esters or fatty acid methyl esters which can be used as “fuel” for vehicles. Approximately, 100 pounds of vegetable oil react with 10 pounds of alcohol (commonly methanol) in the presence of a catalyst, sodium hydroxide; later, 100 pounds of biodiesel and 10 pounds of glycerol (co-product) can be produced. For the glycerol which can be used for pharmaceuticals and cosmetics. Therefore, biodiesel can be considered as totally natural, alternative fuel source to be available for using in most of cases as similar as petrol or more specifically, “diesel distilled from petroleum”. Biodiesel is much safer than diesel from petroleum when biodiesel is escaped to the surrounding environment; moreover, it is much less inflammable as biodiesel’s flashpoint is 130°C as compared to petroleum diesel which is only 52°C.
The atmospheric nitrogen are made available to the plants when nitrogen fixing bacteria or rhizobia fixed atmospheric nitrogen and convert them into ammonia (NH3) in the presence of nitrogenase under different conditions such as, in loose association with other organisms, or in a symbiotic manner with them. The process whereby atmospheric nitrogen is reduced to ammonia in the presence of nitrogenase (found naturally in microorganisms viz. Rhizobium, free living Azotobacter etc) is called Biological nitrogen fixation (BNF). The best example for the symbiotic
The size of the flue gas treatment equipment can be reduced. The flue gas is primarily CO2, suitable for sequestration. Because nitrogen from air is not allowed in, nitrogen oxide production is greatly reduced. Keywords: CO2 rich flue gas, Sequestration, Reduced flue gas volume, Reduced NO Introduction In general process for the combustion in an IC
(source 5) Every single living thing on the planet requires energy to live and energy is produced through food. Plants have there own method in getting their energy which is by using photosynthesis. The equation for photosynthesis is carbon dioxide + water ( using light energy) → glucose + oxygen. Xylems act as the veins of the plants, they take the water through the xylems and the water goes through the leaves. Afterwards, the leaves capture carbon dioxide from the air taking it into the plant.
Natural gas is primarily composed of methane; the main products of combustion of natural gas are carbon dioxide and water vapor; same compounds that are exchaled when breathing. Coal and oil are composed of much more complex molecules with higher carbon ratio and higher nitrogen and sulfur contenents. When combusted, coal and oil release a higher level of harmful emissions that are dangerous to the environment. Coal and fuel oil release ash particles on the environment that are substance that do not burn, instead, it was carried into the atmosphere and contributes to the pollution. Burning natural gas releases a very small of those gasses that are harmful for the environment and contributes pollution to the surroundings.
There is a resistance to utilizing these alternative energies that need to be resolved. To some, the fight for alternative energy may seem unnecessary, but the switch to alternative energy is essential to the survival of our planet and way of life. Our energy needs come from mainly fossil fuels with alternative energy only being a small percentage of the total energy consumption. These fossil fuels create and give off carbon dioxide and greenhouse gasses. These gasses get trapped in our atmosphere and heat our planet.
Methane is the primary electron donor because it is the main food source of organisms, while the chlorinated solvent is a secondary substrate because it does not support the growth of bacteria. In addition to methane, toluene and phenol were used as primary substrates to stimulate the co-metabolism of chlorinated solvents. Another variation of microbial metabolism is reductive dehalogenation. Reductive dehalogenation is potentially important in the detoxification of halogenated organic contaminants, such as chlorinated solvents. In reductive dehalogenation, microbes catalyze a reaction in which a halogen atom on the contaminating molecule is replaced by a hydrogen atom.
Protists are known as algae which plays a vital role in our environment. Plant like protists are called algae, and autotrophs that can make their own food. Algae and autotrophs carry out oxygen there for generating photosynthesis, and then they use the
According to Living in the Environment, Principles, Connections, and Solutions by G. Tyler Miller Jr., natural gas is seen by analysts as a transition fuel between conventional fossil fuels such as coal and oil and renewable sources, like solar, wind, hydroelectric, and geothermal electricity. However, natural gas is still a fossil fuel, regardless of the fact that it burns cleanly. The process of extracting the natural gas, however, is dangerous, and the fact that it cleanly burns is not applicable. When not extracted properly, and even when it is extracted properly, there can be deadly consequences that cannot be
