amphibians have a large variety of antimicrobial peptides that serve as natural innate barriers limiting microbial infection or, in some instances, act as an integral component in response to inflammation or microbial infection. a novel peptide with antibacterial effects and without hemolytic activity was purified from skin secretions of rana ridibunda by multisteps cation-exchange fplc, revers...

One Bacillus thuringiensis (Bt) and two stacked Bt and cowpea trypsin inhibitor (Bt + CpTI) cottons and their non-transgenic isolines were consecutively cultivated to investigate the soil persistence of Cry1Ac and CpTI proteins and their effects on microbial properties and enzyme activities involving C, N, P, and S cycling in soil. Results showed that there were the persistence of Cry1Ac and Cp...

it has been known for years that microbial surface active agents have a wide range of applications not only in oil spill environment but also in many industries. their properties including: (i) changing surface active phenomena, such as lowering of surface and interfacial tensions, (ii) wetting and penetrating actions, (iii) spreading, (iv) hydrophylicity and hydrophobicity actions, (v) microbi...

background and objective: probiotics are live microbial feed supplements which beneficially affect the host animal by improving its intestinal microbial balance, producing metabolites which inhibit the colonization or growth of other microorganisms or by competing with them for resources such as nutrients or space. the aim of this study was to investigate the probiotic properties of candida fam...

In the food industry microbial contamination of surfaces can result in product spoilage which may lead to potential health problems of the consumer. Surface properties can have a substantial effect on microbial retention. The surface characteristics of chemically different coatings (Cu, Ti, Mo, Ag, Fe) were defined using white light profilometry (micro-topography and surface features), atomic f...
