Propionic Acid Research Paper

1629 Words7 Pages

The method of production and separation of propionic acid is a complex one and over the course of years, various methods have been explored, invented and commercialized. The earliest known work performed in the separation of propionic acid dates back to the early 1900’s. To make sure that the work that will be done for this particular project is in a direction that is not explored before, extensive research papers have been read-both form the past and the most recent as well, websites have been searched for possible methods of separation and purification of propionic acid, patents have also been studied. This extensive and long literature survey has given many interesting insights in the process and the conclusions that have been arrived to …show more content…

Bacteria of the genus Propionibacterium will produce propionic acid as an end-product of their anaerobic metabolism. This class of bacteria is generally found in the stomachs of ruminants and the sweat glands of humans, and their activity is partially responsible for the odor of both Swiss cheese and also sweat. It is also biosynthesized in the large intestine of humans by bacterial fermentation of the dietary …show more content…

The solvents that were used in this particular experiment included the likes of - n – hexane, Cyclohexane, cyclohexanol and Cyclohexyl acetate. Further they also reported the distribution coefficient and separation factors. When the two phase region was considered, n hexane and Cyclohexane proved to be suitable agents for establishment of equilibrium data of propionic acid-water-solvent mix. On the other hand, when distribution coefficient values were considered it was shown that Cyclohexyl acetate is most suitable. In conclusion, when all the properties were taken into consideration it could be concluded that cyclohexyl acetate is the most suitable extracting agent that was studied is this research. Another paper investigated the continuous extraction and re-extraction of propionic acid (PA) and acetic acid (AA) in a multimedia hybrid system (MHS). The system was composed of a bulk liquid membrane (BLM) and two strongly basic polymer membranes arranged as: Feed Solution Anion Exchange Membrane Hydrophobic Bulk Liquid Membrane Anion Exchange

Alcaligenes Faecalis Experiment

636 Words | 3 Pages

According to the series of test that my group ran for our unknown specimen, we had a match with the bacteria known as Alcaligenes Faecalis. This bacterium belongs to one of the major group of gram-negative bacteria (Phylum Proteobacteria). Alcaligenes Faecalis (Genus, species) is a rod shaped (bacillus), 0.5-1.2 x 1.0-3.0 µm, round with scalloped margin (colony configuration growth), motile (with one to nine peritrichous flagella), gram-negative, non-fermentative bacteria, obligate aerobic, having oxygen as the principal terminal electron acceptor in the electron transport chain (ETC). We consider we have a match with the species Alcaligenes Faecalis because of the following reasons: Fermentation tests performed (Durham sugars) were negative, which indicate that our bacteria use a different metabolic means for growth (non-fermentative gram-negative bacteria).

Introduction Propionibacterium acnes or former Corynebacterium parvum is an important bacterial agent which acts as a multifunctional microorganism. This bacterium is seen in different parts of the human body; from conjunctivae, oral cavity, and nares to intestinal and respiratory tracts. The biochemical properties of P.acnes are related to the bacterial functions and activities. This bacterium is a slow growing Gram +ive, anaerobic and microaerophilic bacillus which is able to produce propionic acid as a fermentative microbial product.

The bacteria, Pseudomonas Aeruginosa, is gram- negative. This means it is does not have a violet stain. It is also considered a bacillus bacteria. Pseudomonas aeruginosa can be strictly found in aerosols, this means it is compressed in pressure and released into a fine spray. Research has been made and found that this bacterium harms a lot of plants, animals, but mainly humans in such case.

Vitamin C Research Paper

Ascorbic acid with the chemical formula C6H8O6 is comprised of L-dehydroascorbic acid and L-ascorbic acids. Ascorbic acid is most commonly known as Vitamin C, which many know are most commonly found in citrus fruits and some vegetables, eg; oranges, limes, lemons, bell peppers, etc. Vitamin C can be easily oxidized, when the ascorbic acid reacts to form dehydroascorbic acid. This is when two hydrogen atoms are lost, forming two ketone groups. Vitamin C is also a biological compound that is actively involved in the synthesis of collagen which is responsible for the structural protein in the hair, nail and skin growth.

However, this method has been modified suitably under controlled conditionsand has become an industrial tool for partial separation of fatty acids. Temperature-controlled crystallization has been used inthe industry to separate the oleic acid rich fraction from amixture of oleic and linoleic acids. The main disadvantage of this process is poor separation, as the separation is only based on the solidification point, resulting in the contamination of each fraction of the acids with high levels of other acid
