Surfactant Abstract

1533 Words7 Pages

Abstract-
Biosurfactants are surfactants that are produced extracellular or as part of the cell membrane by bacteria, yeasts and fungi. Surfactants are compounds that reduce the surface tension of a liquid, the interfacial tension between two liquids, or that between a liquid and a solid. Surfactants are characteristically organic compounds containing both hydrophobic groups (their tails) and Hydrophilic groups (their heads). Therefore, a surfactant molecule contains both a water insoluble (and oil soluble component) and a water soluble component. Biosurfactants are the surfactants of microbial origin. They offer so many advantages over their synthetic counterparts due to their biodegradable and environmental friendly nature, that’s why gaining much more attention in creating the era of green technology. Biosurfactants are amphiphilic compounds which can reduce surface and interfacial tensions by accumulating at the interface of immiscible fluids and increase the solubility, bioavailability and subsequent biodegradation of hydrophobic or insoluble organic compounds. Their applications range from cosmetic, pharmaceutical and food processes as …show more content…

The biosurfactants from Torulopsis bombicola and Aspergillus ustus MSF3 were used for the release of bitumen from the contaminated soil and for the degradation of hydrocarbons (Cooper DG, Paddock DA, 1984 and Kiran GS et al., 2009). Mannosylerythritol lipids from Candida antarctica have potential applications in the removal and biodegradation of hydrocarbons in oil-contaminated soil and were also used to rinse oil and grease from the contaminated soil (Kitamoto D et al., 2001 and Chaplin MF

    Differential media allows for the differentiation between two similar micro-organisms through how the bacteria may handle certain compounds found in the media or the different reactions that may take place when the bacteria is exposed to the medium (3). Selective media on the other hand allow only certain microbes to grow. This is due to the plate containing a limited amount of nutrients, compounds and chemicals that will deter the growth of certain bacteria (3). Dyes, antimicrobial substances, salts, certain growth inhibitors and, antibiotics are also found on this type of medium (3). The differential and selective media mentioned in this lab are as follows:

    Goals The primary goal of this experiment was to identify an unknown compound by running various tests to determine the qualitative solubility, conductivity, and pH value of the compound. Tests were also performed for the presence of specific cations and anions in the compound. The second goal was to discover the reactivity of the unknown compound by reacting it with different types of substances. The third goal of this project was to calculate the quantitative solubility of the unknown compound in water.

    The discovery of chlorpromazine in 1953 was the main historical milestone in the field of psychiatry. This is not only because chlorpromazine was the first drug that cured symptoms of psychosis; but it also provided clues to identify the biological basis of psychotic disorders like schizophrenia, because of its action on dopamine receptors. After the discovery of chlorpromazine, a lot of antipsychotic drugs were identified to treat psychotic symptoms. Followed by chlorpromazine, other phenothiazines including perphenazine and fluphenazine were introduced.

  • Athabasca Oil Sands Lab Report

    The purpose of this experiment was to separate all components in a mixture that was consisted of water, salt, sand and mineral oil. This was achieved through the knowledge on physical properties of the substances being used, and also through previous understanding of intermolecular forces. This lab is based on the Athabasca Oil Sands, which are located in Northern Alberta, an area that is highly controversial due to its negative impact on the environment and the First Nations People. In 2011, 52 million tons of crude oil were extracted and distilled for fossil fuels, making it one of the largest mining operations in the world. In this area, crude oil exists as bitumen, which is mixed with sediments like sand and clay.

    Studies examining the effect of oil exposure on polar bears indicate that upon petroleum or fuel exposure, polar bears absorb bulk of oil in their hairy coat. After the physical contact, polar bears can metabolize sufficient quantity of oil, causing kidney malfunction, digestive system imbalance, and brain diseases that lead to death. Removal of thick blanket of hair, and skin and eye irritations are few of the other harmful effects (“Polar bears and oil developments”). Species like polar bears and seals are able to absorb oil across their skin, via gastrointestinal tract, or by inhalation. Once absorbed, it spreads to all tissues in varying quantities.

    The results do not support the hypothesis that a higher surface area to volume ratio would result in sulphuric acid being diffused into the agar cubes in the shortest amount of time. This is evident in the results as the exact opposite to what was predicted occurred. Instead of the smallest cube with the largest surface area to volume ratio of 1cm3 having the quickest diffusion rate, it conversely took the longest at 0.092 cm3 per second, whilst the 2cm3 cube with 0.0384 cm3 per second took the least amount of time. This directly refutes the hypothesis. There was also no consistent trend evident in the results.

Many are puzzled by how the production of cyclohexane seems to have become stagnant. Perhaps this is due to the cost of benzene increasing or the demand increasing. Through thorough investigation, the answer to this question and many more can be answered.

Throughout the experiment, scientists observed how the LMPOs were able to degrade xylans, leading to the production of biofuel. Within this article contains interesting information about the production of fuel. I learned that biomass is a source of fuel made from organic matter, and that biorefineries are facilities that integrate biomass into fuel.

    The reaction mixture was then cooled and poured into crushed ice with constant stirring and left overnight. A dark red coloured copolymer was obtained and washed with warm water, methanol and acetone followed by filtration to remove unreacted monomers and impurities. Finally, the copolymer was dried in an air oven at 75 °C for 24 h. The yield of the copolymer was found to be 85%. The copolymer was found to be soluble in solvents like dimethylsulphoxide, dimethylformamide and tetrahydrofuran and partially soluble in mineral acids.

Proteins Proteins are polymers of amino acids that are joined head-to-tail in a long chain that is then collapsed into a three-dimensional structure one of a kind to every sort of protein. The covalent linkage between two contiguous amino acids in a protein (or polypeptide) chain is known as a peptide bond.

  • Lab Report Hydrated Ammonium Sulfate

    954 Words  | 4 Pages

    One of the possible systematic error that may occur in this experiment is that the hydrated (II) ammonium sulfate is contaminated as the iron (II) salt was left uncovered. The iron (II) salt was prepared by the lab assistant and the salt was left at the table uncovered for students to scoop the desired amount of salt they want. The iron (II) salt might be contaminated by dust particles and even saliva. This would cause the standard iron (II) solution to have less iron (II) salt in it and this means that less potassium permanganate solution is needed to titrate the iron (II) solution. This is a systematic error because the iron (II) solution used throughout the experiment.
