The capacity of slightly acidic hypochlorous acid water (SAHW), in both liquid and spray form, to inactivate bacteria was evaluated as a potential candidate for biosecurity enhancement in poultry production. SAHW (containing 50 or 100 ppm chlorine, pH 6) was able to inactivate Escherichia coli and Salmonella Infantis in liquid to below detectable levels (≤2.6 log10 CFU/ml) within 5 sec of expos...

Condensate of black liquor vapors is known to cause corrosion in pulp mill equipment like digesters, flash tanks, storage tanks, evaporator domes, and other equipment handling black liquor condensate. This type of corrosion typically occurs in parts of equipment where the black liquor vapors can condense on a metal surface. Generally organic acids and other wood extractives in the condensate ar...

BACKGROUND Several methanogenic archaea have been detected in the human intestinal microbiota. These intestinal archaea may contaminate medical devices such as colonoscopes. However, no biocide activity has been reported among these human-associated archaea. METHODOLOGY The minimal archaeacidal concentration (MAC) of peracetic acid, chlorhexidine, squalamine and twelve parent synthetic deriva...

Exposure tests in natural atmospheres are an indispensable means for determining the behaviour and durability of metallic materials in the atmosphere. The corrosion behaviour of bare aluminium and anodised aluminium with three different coating thicknesses has been evaluated for two years' exposure in two natural atmospheres of very different corrosivities: one urban and the other marine. Sever...

Several factors may contribute to the structural failure of cast and ductile iron water mains, the most important of which is considered to be corrosion. The ANSI/AWWA C105/A21.5–99 10-point scoring (10-P) method is commonly used to predict corrosivity potential of a given soil sample using certain soil properties. The 10-P and other scoring methods use binary logic to classify the soil either ...

This search aims to evaluate the corrosivity of AISI 1020 steel in clayey soil through microbiological analyzes and mass loss technique. Through results obtained, according identification methodology Bergey manual, presence two microorganisms was verified, Acidithiobacillus thiooxidans ferrooxidans , responsible for biocorrosion process addition filamentous fungi. The these bacteria does not ge...

in this paper pi, szeged and revised szeged indices of an infinite family of ipr fullereneswith exactly 60+12n carbon atoms are computed. a gap program is also presented that isuseful for our calculations.

Abstract Although it is well known that microbes play a significant role in marine corrosion, few studies have systematically studied the relationship between microorganisms and corrosion products under long-term immersion. In this study, characteristics of rust layer formed on carbon steel immersed South China Sea for 5.5 years were investigated using various surface analysis microbial communi...
