What beneftis the Bifidobacterium bifidum has?

Bifidobacterium bifidum is  a beneficial kind of bacteria. Probiotics live inside the body, mainly in the gastrointestinal system. These good bacteria promote healthy digestion, strengthen the immune system, and work to eliminate harmful and unhealthy bacteria from the body. Low levels of probiotics in the intestines can result in many unpleasant symptoms such as abdominal bloating and cramps, yeast infections, and food sensitivities. Bifidobacterium bifidumcan be added to the diet through the use of supplements or the consumption of yogurt containing live culture.

Bifidobacterium bifidum is one of many bacteria found in the human body. The digestive system is home to an estimated 500 different species of bacteria, including members of the Bifidobacterium, Lactobacillus, Clostridium, Fusobacterium, and Bacteroids families. In addition to these good bacteria, the human gut flora also includes a number of strains of yeast or fungi. Although the largest population of Bifidobacterium bifidum is located in the digestive system, lesser amounts are also found in the mouth, breast milk, and the vagina. Bifidobacterium bifidum known as B. bifidum, is a strain of bacteria commonly used as a probiotic. Probiotics are living microorganisms that simulate the beneficial bacteria found in the gastrointestinal tract of humans. B. bifidum is one of many bacterial strains that occur naturally in the gut flora, living in the colon. The inclusion of B. bifidum in a dietary regimen provides the host with a variety of benefits.

Applications of Bifidobacterium Brevis

Bifidobacterium is a genus of Gram-positive, non-motile, often branched anaerobic bacteria. They are ubiquitous, endosymbiotic inhabitants of the gastrointestinal tract, vagina and mouth (B. dentium) of mammals and other animals. Bifidobacteria are one of the major genera of bacteria that make up the colon flora in mammals. Some bifidobacteria are used as probiotics.

Bifidobacterium Brevis can improve children’s acute diarrhea and antibiotic cause of diarrhea, increase the white defensive capabilities.

Before the 1960s, Bifidobacterium species were collectively referred to as “Lactobacillus bifidus”.

Bifidobacterium brevis is acid-resistant and very sensitive to antibiotics and mostly distributed in the colon, Bifidobacterium brevis can inhibit the growth of harmful bacteria in intestines and help digestion.  Bifidobacterium Brevis can decomposition up to more than 20 kinds of carbohydrates, and it produce natural antibiotics and lactic acid. Bifidobacterium brevis is one of the most common probiotics in health food.

Monosodium Glutamate’s Production and Chemical Properties

Since the first time that monosodium glutamate (MSG) was released into the market, it has been produced by three methods: (1) hydrolysis of vegetable proteins with hydrochloric acid to disrupt peptide bonds (1909–1962), (2) direct chemical synthesis with acrylonitrile (1962–1973), and (3) bacterial fermentation; the current method.

Initially, wheat gluten was used for hydrolysis because it contains more than 30 g of glutamate and glutamine in 100 g of protein. But as the production to achieve the ever-increasing demand for MSG augmented, new production processes were studied: chemical synthesis and fermentation. The polyacrylic fiber industry began in Japan in the mid 1950s and acrylonitrile was adopted then as starting material to synthesize MSG.

Currently, most of the world production of MSG is by bacterial fermentation in a process similar to wine, vinegar, yogurt and even chocolate. Sodium is added later through the step of neutralization. During fermentation, selected bacteria (coryneform bacteria) cultured with ammonia and carbohydrates from sugar beets, sugar cane, tapioca or molasses, excrete amino acids into the culture broth from where L-glutamate is isolated. Kyowa Hakko Kogyo Co Ltd developed the first industrial fermentation to produce L-glutamate. Nowadays, the conversion yield and production rate from sugars to glutamate continues to improve in the industrial production of MSG, which allows for keeping up with demand. The final product after filtration, concentration, acidification and crystallization is pure glutamate, sodium and water. It appears as a white and odorless crystalline powder that in solution dissociates into glutamate and sodium. It is freely soluble in water, but not hygroscopic and practically insoluble in common organic solvents such as ether. In general, MSG is stable under the conditions of regular food processing. During cooking, MSG does not decompose, but like other amino acids, browning or Maillard reactions will occur in the presence of sugars at very high temperatures.

Enzyme-linked immunosorbent assay (ELISA), is a popular format of a “wet-lab” type analytic biochemistry assay that uses one sub-type of heterogeneous, solid-phase enzyme immunoassay (EIA) to detect the presence of a substance in a liquid sample or wet sample.

As a “wet lab” analytic biochemistry assay, ELISA involves detection of an “analyte” (i.e. the specific substance whose presence is being quantitatively or qualitatively analyzed) in a liquid sample by a method that continues to use liquid reagents during the “analysis” (i.e. controlled sequence of biochemical reactions that will generate a signal which can be easily measured quantified and interpreted as a measure of the amount of analyte in the sample) that stays liquid and remains inside a reaction chamber or well that is needed to keep the reactants contained; It is opposed to “dry lab” that can use dry strips – and even if the sample is liquid (e.g. a measured small drop), the final detection step in “dry” analysis involves reading of a dried strip by methods such as reflectometry and does not need a reaction containment chamber to prevent spillover or mixing between samples.

Ferrochrome (FeCr) is an alloy of chromium and iron containing between 50% and 70% chromium. The ferrochrome is produced by electric arc melting of chromite, an iron magnesium chromium oxide and the most important chromium ore. Most of the world’s ferrochrome is produced in South Africa, Kazakhstan and India, which have large domestic chromite resources. Increasing amounts are coming from Russia and China. The production of steel is the largest consumer of ferrochrome, especially the production of stainless steel with chromium content of 10 to 20% is the main application of ferrochrome.

Ferrochrome is often classified by the amount of carbon and chrome it contains. The vast majority of FeCr produced is charge chrome from Southern Africa. With high carbon being the second largest segment followed by the smaller sectors of low carbon and intermediate carbon material.

A Study on 1-Bromohexadecane

Item Name: 1-Bromohexadecane
Molecular Formula: C16H33Br
CAS No.: 112-82-3
Synonyms: N-HEXADECYL BROMIDE;HEXADECYL BROMIDE;CETYL BROMIDE;1-BROMOHEXADECANE;1-HEXADECYL BROMIDE;1-Bromhexadecan;1-bromo-hexadecan

In a paper, people present the results of using alkane derivatives to assist in the adsorption of planar molecules by employing 1-bromohexadecane(C16Br) and phthalocyanine (Pc) as examples. Their assembly behaviors have been well resolved on the observed STM images. The observations presented in this work demonstrate that single molecular arrays of Pc can be obtained with a template of C16Br on highly oriented pyrolytic graphite (HOPG) substrate surface to allow high-resolution STM studies. Binary mixtures of different molar ratios were also observed. By adjusting the molar ratio of Pc to C16Br to about 1:3–1:4, uniform assembly can become dominative on the surface. The resulting high stability and the well ordered assembly are attributed to the increased adsorption barrier of alkanes. This approach could be adapted to the studies of other molecules to observe molecular features and could be helpful in obtaining two-dimensional assemblies of monodispersed molecules, especially planar molecules.

Viny Chloride’s Production

Vinyl chloride is produced on a substantial scale – approximately 31.1 million tons (7.5 Bel tons) were produced in 2000. Two methods are employed, the hydrochlorination of acetylene and the dehydrochlorination of ethylene dichloride (1,2-dichloroethane).

Manufacturing details from ethylene dichloride
Direct chlorination
The production of vinyl chloride from 1,2-dichloroethane (EDC) consists of a series of well-defined steps. EDC is prepared by reacting ethylene and chlorine. In the presence of iron(III) chloride as a catalyst, these compounds react exothermically:

CH2=CH2 + Cl2 → ClCH2CH2Cl
This process is very selective, resulting in high purity EDC and high yields. However any dissolved catalyst and moisture must be removed before EDC enters the VCM production process.

Thermal cracking
When heated to 500 °C at 15–30 atm (1.5 to 3 MPa) pressure, EDC vapor decomposes to produce vinyl chloride and anhydrous HCl.

ClCH2CH2Cl → CH2=CHCl + HCl
The thermal cracking reaction is highly endothermic, and is generally carried out in a fired heater. Even though residence time and temperature are carefully controlled, it produces significant quantities of chlorinated hydrocarbon side products. In practice, EDC conversion is relatively low (50 to 60 percent). The furnace effluent is immediately quenched with cold EDC to stop undesirable side reactions. The resulting vapor-liquid mixture then goes to a purification system. Some processes use an absorber-stripper system to separate HCl from the chlorinated hydrocarbons, while other processes use a refrigerated continuous distillation system.

Oxychlorination
Modern VCM plants use recycled HCl to produce more EDC via oxychlorination, which entails the reaction of ethylene, oxygen and hydrogen chloride over a copper(II) chloride catalyst to produce EDC:

CH2=CH2 + 2 HCl + ½ O2 → ClCH2CH2Cl + H2O.
The reaction is highly exothermic.

Due to the relatively low cost of ethylene, compared to acetylene, most vinyl chloride has been produced via this technique since the late 1950s. This is despite the lower yields, lower product purity and higher costs for waste treatment. By-products of the oxychlorination reaction, may be recovered, as feedstocks for chlorinated solvents production. One useful byproduct of the oxychlorination is ethyl chloride, a topical anesthetic.

Waste treatment
For environmental reasons, the acidic aqueous wastestream is treated to remove organic compounds and neutralized before it can be sent to the plant’s “outfall”. An outfall is a monitored wastewater stream that must conform to the plant’s standards. Some very hazardous wastes are generated in the recovery of the product vinyl chloride. These wastes require specialized procedures. These wastes are burned onsite in hazardous waste burners that again are subject to strict standards.
