Bacteriostatics and fungistatics
The innovation and technological center of JSC “IVKHIMPROM” presents a number of agents for bacteriostatic and fungistatic treatment (bacteriostatic and fungistatic). To find out about the terms of purchase, contact us by phone / fax: 8 (4932) 570112, 570121.
In manufacturing processes, many materials, fluids and equipment are subject to microbial contamination, which can be caused by a wide variety of factors.
Main sources of infection
First of all, this is the use of raw materials and water affected by microorganisms: improper storage of water, recirculation (flush) water, water supply from natural sources.
Secondly, the sources of equipment contamination can be its unsuccessful layout, the presence of “dead zones”, and poor equipment maintenance. Favorable conditions for the reproduction of bacteria and fungi are most often created during stagnation, accumulation of affected materials in one place.
Thirdly, the causes of infection are poor hygiene, unsanitary conditions at work and ineffective disinfection. Spores of fungi and bacteria can be brought in by the hands of employees. Dust, moisture and insufficient ventilation act as catalysts for bacterial growth. Fungal spores are easily airborne, adhere to dust particles, and develop rapidly in a humid environment. Fungal spores are known to be highly resistant to external influences – some species survive at temperatures below 0 ° C and at elevated temperatures up to 80 ° C, withstand very low humidity. They seem to fall into suspended animation and, even if the main culture dies, they wait for the temperature and humidity to return to normal in order to resume their development.
Even with a thorough rinsing of the room or equipment, there are areas that are difficult to clean. Over time, a biofilm begins to form in such places – microorganisms living on the walls of tanks. These microorganisms are often difficult to detect with the naked eye, but under a microscope it can be seen that they are a conglomerate of fungi and bacteria that invade microbial extracellular products, organic matter residues, and corrosion products. Biofilm is a frequent intruder in the “dead zones” of equipment.
Dangerous consequences of infections
The consequences of such microbial “implants” are different. Their primary impact is a change in the physical properties of the equipment, for example, a decrease in strength. The secondary effect is manifested after the release of metabolic products and electrolytes by microbes and becomes the cause of premature aging, oxidation and destruction.
In addition, moisture remains in the mycelium of mushrooms for a long time, which, even after processing the room, leads to damage to products and equipment.
A great danger for contamination of all equipment is its complexity and the presence of internal connections through which microorganisms move from one part to another and reduce their biostability. Biofilm formation can corrode the surface of the equipment walls, and as a result, block nozzles, pipes and filters. With further development, fungi and bacteria begin to emit an unpleasant odor and spoil the appearance of the product.
The listed consequences of the introduction of microorganisms into materials are dangerous by reducing the service life of the product, and this, if anti-corrosion treatment with inhibitors and pH regulators is not used, can lead to the replacement of the affected parts or even the entire equipment.
Means for combating bacterial and fungal infections
Many manufacturing plants, knowing the dangers of contamination with harmful bacteria and not wanting to incur additional costs, treat products with biocides.
Biocides are chemicals that inhibit the growth and reproduction of bacteria and fungi. To stop the development of bacteria, bacteriostatics are used, and fungi – fungistatics. There are also complexes of biocides with the properties of both bacteriostatic and fungistatic.
