Bacteriostatic properties

Food apphcations of sorbates expanded rapidly after issuance of the original patents in 1945 (92). The first uses were based on their excellent fungistatic properties and thus involved foods with low pH and/or low water activity in which yeasts and molds are the primary spoilage agents. More recent appHcation research has been directed toward utilizing the bacteriostatic properties of sorbates. 

Some phosphorus-containing surfactants have bacteriostatic properties. In combination with their physiological acceptance they are used in cosmetics and pharmaceuticals. In mutanase oral anticarie compositions the combination of alkyl phosphates and nonionic surfactants stabilizes mutanase. A dentifrice useful for prevention of dental caries contains 0.5% sodium lauryl phosphate and 1.5% polyoxyethylene (20) sorbitan monooleate [222]. 

Studies to elucidate the mode of bacteriostatic property of xanthostatin (XS), a novel depsipeptide antibiotic with an A/-acetylglydne side chain and selective antimicrobial activity against Xanthomonas spp., were carried ont by Kim and coworkers [80]. Two biotransformed XSs were isolated by the treatment of XS with the cell... 

The results showed that silver particles are sufficiently bound to the cotton fabric, which can retain good bacteriostatic properties even after 10 cycles of washing. 

The chemistry of organic azides has been the subject of many theoretical and practical investigations. Apart from their application as explosives some organic azides possess interesting pharmacological and bacteriostatic properties. 

Vanillin itself has some bacteriostatic properties and therefore has been used in formulations to treat dermatitis. Hydrazones of vanillin have been shown to have a herbicidal action similar lo that of 2.4-D, and the zinc salts of dithiovanillic acid. A new potential use for vanillin is as a ripening agent to increase the yield of sucrose in sugarcane by the treatment of the cane crop a few weeks before harvest...

In contrast, there are substances like some nitrofurane derivatives for which the presence of particular molecular structures is the decisive condition. Thus, a nitrofurane derivative prepared by Casini and his co-workers (87) has shown bacteriostatic properties similar to classical low molecular preparations of nitrofurane, e.g. l-[5-(nitrofurfuryliden)amino]hydantoine. The polymeric substance shows an activity considerably longer than that of the reference substance if parenterally applied, whereas oral application gives no effect. This is easy to understand because, as already mentioned, polymers cannot be resorbed in the digestive tract. Here, the active polymeric substance [22] has been prepared by condensation of 5-nitrofuraldehyde with poly(acryloylhydrazide). 

Propolis (SEDA-12, 410) (SEDA-13, 459) (SEDA-18, 4) or bee-glue is a resinous material used by bees to seal hive walls and to strengthen the borders of the combs and the hive entrance. It has antiseptic, antimycotic, and bacteriostatic properties and is found in cosmetics and natural products for self-treatment.

The synthesis and preparation of macromolecules with bactericidal or bacteriostatic properties are reviewed. The synthesis of polymers with antibacterial groups and the irmnobilisation of antibacterial reagents, such as iodine, qrratemary ammonitrm salts or antibiotics, are presented. Particular attention is paid to bacterium-adsorbing polymers, which can remove bacterial cells from aqueous media. Filter membranes coated with bacteria-adsorbing macromolectrles are also discussed. 103 refs.

L-Alanine is produced at a level of 10 tons/month using this kind of high pressure column reactor system. L-Alanine is useful as an additive to both entheral and parenteral nutrition, being a food additive with a sweet taste and bacteriostatic properties [2]. 

Cationic surfactants contain quaternary ammonium ions as their hydrophilic parts (Table 30.3). This class of surfactants has gained importance because of its bacteriostatic properties. Therefore, cationic surfactants are applied as disinfectants and antiseptic components in personal care products and medicine. Because of their high adsorptivity to a wide variety of surfaces, they are used as antistatic agents, textile softeners, corrosion inhibitors, and flotation agents.
