Production/productivity marine

This series in heterocychc chemistry is being introduced to collectively make available critically and comprehensively reviewed hterature scattered in various journals as papers and review articles. All sorts of heterocyclic compounds originating from synthesis, natural products, marine products, insects, etc. will be covered. Several heterocyclic compounds play a significant role in maintaining life. Blood constituents hemoglobin and purines, as well as pyrimidines, are constituents of nucleic acid (DNA and RNA). Several amino acids, carbohydrates, vitamins, alkaloids, antibiotics, etc. are also heterocyclic compounds that are essential for life. Heterocyclic compounds are widely used in clinical practice as drugs, but all applications of heterocyclic medicines can not be discussed in detail. In addition to such applications, heterocyclic compounds also find several applications in the plastics industry, in photography as sensitizers and developers, and the in dye industry as dyes, etc. 

Dimethylsulfoniopropionate (DMSP) is an organic sulfur compound that occurs at high concentrations in many marine algae and plants, wnere it fulfills an osmotic function (1.21. DMSP is a principal form of organic sulfur in productive marine environments and its microbial catabolism entails either enzymatic cleavage to dimethyl sulfide (DMS) and aciylate (3.41 ...

Under certain conditions, the use of organic acids may enhance the growth of some fungal strains in bakery products (Marin et al., 2002). For example, a low concentration of sorbic acid (0.025 and 0.05%), almost without exception, has been shown to enhance fungal growth, regardless of aw and temperature levels (Samelis et al., 2002). Potassium benzoate (at a concentration of 2 mM) has been found to produce an increase in growth rate of 52% in Z. bailii cells (Macpherson et al., 2005). 

Gudmundsson and Borrehaug have presented results from a study to determine the feasibility of transporting natural gas in the frozen hydrate form. A NGH transportation chain comprises hydrate production, marine transport, and regasification elements. Even after a conservative economic analysis, it was found that the capital cost associated with an NGH chain will be 28% lower than the equivalent LNG chain. Takaoki et al. found that the most suitable way to store hydrate for transportation was as small pellets.

The following are key examples of how microwave thermal processing could affect the physical and chemical properties of a food material being processed. Each example represents major research areas in food processing, for example, fruits and vegetables, dairy products, meat products, marine products, and essential oils.

L. is widely used as acidulator and preservative (- food additives) in pickled products, marinated fish, cheese, cider, wine, meat and poultry. Technical applications include leather auxiliaries, rust remover in metal treatment and - coatings. Derivatives of importance are Na- and Ca-lactates, wdiich are used in the food industry. 

In 1993, French consumption of these products was around 6 Mt and 2.5 Mt respectively for use in burners and in diesel engines. The latter figure appears in the statistics under the heading, marine bunker fuel . Its consumption been relatively stable for several years, whereas heavy industrial fuel use has diminished considerably owing to the development of nuclear energy. However, it seems that heavy fuel consumption has reached a bottom limit in areas where it is difficult to replace, e.g., cement plants. 

Carbonate rocks are not normally transported over long distances, and we find carbonate reservoir rocks mostly at the location of origin, in situ . They are usually the product of marine organisms. However, carbonates are often severely affected by diagenetic processes. A more detailed description of altered carbonates and their reservoir properties is given below in the description of diagenesis .
