Often, new life at hydrothermal vents begins with a burst of bacteria from the opening of the vent. These bacterias can endure high temperatures more than any other organism (Masters). Plants and organisms that live near hydrothermal vents use a process called chemosynthesis, allowing organisms to use energy released by inorganic chemical reactions to produce food (“Ocean Explorer”). Some bacteria and archaea cannot withstand the hot hydrothermal fluids of black smokers, but they thrive just outside the extreme heat of the water (“The Microbes That Keep Hydrothermal Vents Pumping”). Also, being close enough to the chimney but far enough from the heat allows bacteria to gather
However, the cons are they can cause diseases, pathogenic, and etc. Without bacteria there will be no life in the world, as it is responsible for beginning everything. The next domain and kingdom to exist was Archaea. They are organisms that can survive in extreme habitats as in volcanoes, deserts, and even Antarctica. They are heat loving bacteria which are called Extreme Thermophiles, and
Enzymes are proteins that catalyze chemical reaction, and they work best at their optimal conditions (optimum pH, temperature etc.) but when the environment is not close to the optimum conditions, the enzymes denature and do not function anymore1. An excellent example would of the effect of temperature on yeast fermentation would be that the bacterial cells if exposed to very high temperature (above the optimal) would no longer function since their enzymes are denatured. The yeast would produce the most Carbon dioxide in the optimal temperature (45 °C ±1/°C) and other temperatures below the optimal temperature would not produce sufficient Carbon dioxide and any temperature above will produce too much that it will lead to the sinking of the bread and death of yeast because its enzymes have been denatured, therefore the reaction will stop. The bread will certainly sink if is not exposed to the right temperature the yeast will not ferment
Water on hydrophobic surfaces will display a high contact point. Superhydrophobic surfaces are exceptionally hydrophobic, i.e., greatly hard to wet. The contact angle of a water droplet surpasses 150° and the contact angle hysteresis is under 10°. This is also referred to as the Lotus impact, after the superhydrophobic leaves of the lotus plant.Rough and microstructured surfaces characteristically build hydrophobicity of hydrophobic surfaces through two altogether
In precipitation process, large volumes of sludge are generated which can present dewatering and disposal problems , as well as re-carbonation of the softened water are needed . Ion-exchange resin have been widely used to remove calcium and magnesium ions due to their many advantages, such as high capacity and fast kinetics [12-14]. However, ion-exchange resins must be regenerated by chemical reagents when they are saturated and the regeneration can cause serious secondary pollution. In large scale, application of resin is expensive . In recent years, various method such as nanofiltration [15, 16], capacitive deionization , electrodialysis , electrochemical treatment  and, adsorption [20, 21] have been widely studied for ions removal from aqueous solution, especially water softening.
Multiple factors affect the activity of an enzyme (1). These factors include the pH and the temperature of the solution (1). Most enzymes have a preferred temperature and pH range (2). The preferred temperature for catalase falls between the ranges of thirty five to fifty degrees Celsius (4). Temperatures that are too high denature the enzyme and halt the enzyme’s activity (2).
Enzymes are one the most powerful catalysts and play an important role in living organisms as they allow reactions which would normally require extreme temperatures to occur in all living cells without destroying the organic matter. For a chemical reaction to occur a minimum threshold must be exceeded for a process to occur. This is the activation energy. Enzymes catalyse reactions by lowering the activation energy of a chemical reaction which allows the reaction to happen at lower temperatures. Enzymes are proteins and have a specific shape for its specific function.
An organism that thrives at high pressures is called a piezophile or barophile. These organisms have a waxy cell layer that helps them survive the crushing pressures found below the sea. It has been difficult for studies to be done on such organisms because of the pressure and temperature barrier. A study done on bacteria from the Mariana trench concluded that “much of deep-sea microbiology may have been done with spurious deep-sea organisms due to warming of samples” (Yayanos, Dietz and Boxtel, 1981). The pressure of the deep ocean is incredibly hard to recreate in a
In the alkali-catalyzed process, the presence of free fatty acid (greater than 1 mg/g KOH) and water in the oil can cause high amounts of undesirable soap formation, also consuming some quantity of alkaline catalyst and reduces the eﬀectiveness, all of which result in a lower conversion. Therefore, for the feedstock with high free fatty acids, it is essential to have a pretreatment stage before subjecting it to transesteriﬁcation process.  1.2 Pretreatment Process for Waste Cooking Oil Pretreatment of waste cooking oil consists of physical treatment for removing the suspended solid contaminants and chemical treatment processes mainly for deacidiﬁcation. A ﬂow sheet giving the diﬀerent approaches for pretreatment of waste cooking oil is shown in Figure 2. Issariyakul et al.
Researchers agree that this ‘ultra-food’ is more valuable and potent than virtually all the ‘superfoods’ we rave about today. NASA says it is intricately connected to life on Earth as it is believed to produce up to 90% of the oxygen present in the planet. To put this in another way, if this item is completely destroyed, the earth would become uninhabitable for many organisms – including humans. This wonderful ‘ultra-food’ is known as phytoplankton. Phytoplankton basically refers to numerous aquatic microscopic organisms that utilize light and dissolved carbon dioxide to produce their energy and nutritional requirements.
When inhaled it stops the oxygen that gets to the brain and can be life threatening. When natural gas builds up it causes explosions also. Many people use natural gas to heat their water, but there are many reports of the water being contaminated and making people sick and their animals sick due to natural gas water heaters exploding. If a water heater explodes it can contaminate many water supplies not just one, if in town the water will contaminate some if not all of the households and it could expand further out. Today fracking in the United States is very common and very helpful, fracking produces natural gas which is used to fuel vehicles, heat homes and businesses, and is also used to cook with, although natural gas has its perks it also is a tad bit dangerous if not consumed correctly.
