Microbiologically susceptibility

It may be possible to use less microbiologically susceptible raw materials. For example, hydroxypropyl methyl cellulose has been shown to be more resistant than hydroxyethyl and carboxymethyl cellulose (Briggs, 1980). 

In addition to primary-contaminated or microbiologically susceptible natural raw materials, many multiactive agents classes are based on an alcoholic or phenolic structure. These extracts, such as melissa extract, rosemary acids, phenylethylalcohol II, 1.6.] etc., often show strong microbial efficacy and can be used to support product preservation in cosmetics (Eggensperger, 2001).

Poultry, Fish. About a quarter of food products in the United States are meats, including beef, poultry, fish, lamb, veal, and pork. AH of these are susceptible to microbiological, en2ymatic, and physical changes. 

Poultry, susceptible to microbiological deterioration, is an excellent substrate for Salmonella. Therefore, the temperature is reduced as rapidly as possible after slaughter. Packagiag at factory level is in soft film, ie, low density polyethylene or plastici2ed PVC, which retards water-vapor loss and permits oxygen entry. 

Gandy. Chocolate is subject to flavor or microbiological change. Inclusions such as nuts and fillings such as caramel are susceptible to water gain or loss. Chocolates, which are stable, are packaged in greaseproof papers and moisture/fat barriers such as polypropylene film (see Chocolate and cocoa). 

Many tracer chemicals are inherently unstable even as the unlabeled forms. Susceptibility of a chemical to hydrolysis, oxidation, photolysis, and microbiological degradation needs to be evaluated when designing suitable storage conditions for the labeled compound. Eactors that reduce radiolytic degradation, such as dispersal in solution, are apt to increase chemical degradation or instability. 

Open-loop systems have inherently long residence times which may be detrimental if the retentate is susceptible to degradation by shear or microbiological contamination. A feed-bleed or closed-loop configuration is a one-stage continuous membrane system. At steady state, the upstream... 

Nitrite formulations are employed for both hot and cold water closed loops (and also occasionally for open cooling systems). Unfortunately, nitrite is easily oxidized to nitrate and is very susceptible to microbiological attack (by Nitrobacter agilis and other microorganisms). Nevertheless, it is a good low-cost passivating inhibitor. 

Possible exposure to pesticide-derived N,-nitroso compounds depends on environmental processes that influence formation, movement, and degradation of the compounds. Although laboratory studies have shown the feasibility of environmental nitrosamine formation, there has been little evidence that it is an important process. Nitrosamines vary greatly in their environmental stabilities, but all seem to be susceptible to one or more modes of decomposition including photolysis, microbiological degradation, and plant metabolism. 

Bacterial corrosion is often referred to as microbiologically influenced corrosion. MIC involves the initiation or acceleration of corrosion by microorganisms. The metabolic products of microorganisms appear to affect most engineering materials, but the more commonly used corrosion-resistant alloys, such as stainless steels, seem to be particularly susceptible. 

Because of the raw materials that they contain and the conditions under which they are manufactured and stored, water based paints are highly susceptible to microbiological infection and spoilage in the wet-state.

The saturated hydrocarbon moieties give lipids an aliphatic character, and thus hydro-phobic properties, which limit their loss from artefacts by water leaching. However, they are subject to chemical and microbiological alterations since they have a limited number of reactive sites, they are relatively less susceptible to structural modification and degradation than polysaccharides, proteins and nucleotides. 

The selection of a specific agent or combination should be based on culture and susceptibility data for peritonitis that occurs from chronic peritoneal dialysis. If microbiologic data are unavailable, empiric therapy should be initiated. 

A-10.2.1 Test Fluid (See Para. IP-10.7.1). Consideration should be given to susceptibility to microbiologi-cally influenced corrosion (MIC). This condition is especially prevalent in no-flow, high-moisture environments. Internal MIC may also depend on the characteristics of the treated or untreated test fluid. Internal MIC may be lessened or possibly eliminated by properly draining and drying systems and / or by proper selection of test fluid. 

Microbiological Quality of Tofu. Tofu is a protein-rich substrate with pH around 6, hence it is quite susceptible to microbial growth. Traditionally, tofu has been made and consumed in the same day. However, in the United States, tofu may be held at the supermarkets for many days on produce counters before consumption where temperatures are usually 10-15°C. Thus, microbial deterioration becomes a serious problem (23-25).

Pigment slurries are one of the major components in paints and coatings that contribute to or affect the performance of a formulation. The nature of pigment slurries makes them extremely susceptible to microbiological contamination that can degrade the final formulation. Often biodeterioration can be prevented with plant sanitation and the use of a preservative, but formulators must not rely on the precept that a particular preservative that works today will always remain effective down the road. In complex environments, contaminants can enter the system at different points, or a formulation change may render the original preservative less effective. Manufacturers must remain aware of trends in the industry to ensure their products are properly protected.
