Descrição: Oil spills cause devastation to the environment, killing sea life, birds, and coastal plants. Spraying areas of contamination with oil-eating microbes accelerates the degradation of the oil. This process is known as bioremediation. In this open-ended experiment, students grow a mixture of oil-eating bacteria and observe their effectiveness at degrading a variety of oils.

Descrição: MP EcoChrom™ SILICA is used as a suspending and thickening agent in pharmaceutical.A silica-based aerogel was used in the Stardust spacecraft to collect extraterrestrial particles. Silica is also used in the extraction of DNA and RNA due to its ability to bind to the nucleic acids under the presence of chaotropes. As hydrophobic silica it is used as a defoamer component. In hydrated form, it is used in toothpaste as a hard abrasive to remove tooth plaque. SiO2 has a number of distinct crystalline forms (polymorphs) in addition to amorphous forms. In the majority of silicates, the Si atom shows tetrahedral coordination, with 4 oxygen atoms surrounding a central Si atom.

MP EcoChrom™ Silica, the chemical compound silicon dioxide, also known as silica (from the Latin silex), is an oxide of silicon with the chemical formula SiO2 with a mean pore size of 60Å and particles size of 200-500μm. MP silica are free of particles outside the standard range. The irregular shape of MP Silica permits the easy packing of column permeability and plate number. They allow easy switching from one sieve cut to another, offering an easy way to change the chromatographic methods. It has been known for its hardness since ancient times. Silica is most commonly found in nature as sand or quartz, as well as in the cell walls of diatoms.

Sodium chloride is a commonly used chemical which is found widely in nature. It is considered to be an essential nutrient. Excess amounts of sodium chloride can destroy electrolyte balance and cause death in most animals, including humans.
Sodium chloride is used in a wide variety of biochemical applications, including intravenous fluids (normal saline is 0.9% w/v in water), density gradients, a diluent to increase ionic strength in buffers or culture media and in salt-out procedures in the isolation of DNA. It has also been used in high concentrations for preservation of foods since bacteria cannot grow in high salt conditions. Sodium chloride is widely used in protein crystallization.

Sodium chloride is used in a wide variety of biochemical applications, including intravenous fluids (normal saline is 0.9% w/v in water 10), density gradients 3,6, a diluent to increase ionic strength in buffers or culture media and in salt-out procedures in the isolation of DNA. It has also been used in high concentrations for preservation of foods since bacteria cannot grow in high salt conditions. A salt-ice mixture in the ratio of approximately 33 g sodium chloride to 100 g ice (at -1°C) will drop in temperature to as low as -21°C, depending on the rate of stirring and the size of the ice chunks.

Descrição: Agar is a polysaccharide complex extracted by bleaching and hot water treatment of agarocytes from the red alga Rhodophyceae, and usually consisting of the genera Gelidium, Acanthopeltis, Ceramium, Pterocladia and Gracilaria. The algae are typically found in the Pacific and Indian Oceans and in the Sea of Japan. It is primarily composed of two different units: Agarose and Agaropectin; Agarose is a neutral gelling component which is composed of a linear polymer of alternating D-galactose and 3,6-anhydrogalactose units. Agaropectin is a non-gelling component which consists of D-1,3-glycosidically linked D-galactose units, some of which are sulfated at the 6th position.
Agar is specially purified for use in preparing solid culture media for microbiological and bacteriological applications.
