Optimal Conditions

The surfaces of building materials of hydrotechnical constructions undergo the process of algae biofouling. The degree of damage depends on the environmental factors that are affect-ed by the level of anthropogenic load areas. Modeling the biofouling process of concrete with algae under laboratory conditions has allowed determining their impact on the building ma-terial, accompanied by changes in chemical and mineralogical composition of the surface of products. The microscopic examination of sample’s surfaces and evaluation of the effective-ness of various ions leaching from building materials shows the results of "algal attack" relat-ed to the acceleration of biodegradation of materials under the influence of aggressive meta-bolic products, mechanical action neoplasms, creating optimal conditions for the development of subsequent aerobic microbial decomposers. To clarify the nature of chemical processes in the system “algocenosis – concrete” the changes of chemical and phase (mineralogical) com-position of the surface layer of concrete sample were studied. The effect that algae produce on hydraulic engineering constructions is due to the fact that these organisms, belonging to phototrophs and standing at the beginning of the food chain, initiate new microbial growth.

Multiple Challenges

Salmonellosis is known to be one of important issues that affect poultry industry as well as it can affect human health. Recently, multiple challenges are facing the use of natural antibacterial compounds, such as herbal extracts to overcome the massive increase in bacterial antibiotic resistance. Different Salmonella serotypes were recovered throughout examination of diarrheic poultry. These strains showed multidrug resistance by disc diffusion methods also, the resistance genes qnrS and aac (6′)-Ib-cr were detected in S. Enteritidis and S.Typhimurium which isolated from broiler's organs and muscles. The methanolic extracts of five plants (Alhagi maurorum, Conyza dioscoridis, Coriander sativum, Caracuma longa and Cuminum cyminum) were tested for their antibacterial activity against different isolated Salmonella serotypes using minimum inhibitory concentrations (MIC). Conyza dioscoridis was the most effective extract retarding microbial growth of Salmonella Enteritidis, while other plant extracts showed variable antimicrobial activity. These results are promising in the way of replacing the antibiotic therapy with natural substances to overcome the multidrug resistance.
