Antimicrobial non-porous surfaces: a comparison of the standards ISO 22196:2011 and the recently published ISO 7581:2023.

The application of antimicrobial surfaces requires the proof of their effectivity by methods in laboratories. One of the most well-known test methods is ISO 22196:2011, which represents a simple and inexpensive protocol by applying the bacterial suspension with known volume and concentration covered under a polyethylene film on the surfaces. The incubation is then done under defined humidity conditions for 24 h.

Fiber-based food packaging materials in view of bacterial growth and survival capacities.

Understanding interactions of bacteria with fiber-based packaging materials is fundamental for appropriate food packaging. We propose a laboratory model to evaluate microbial growth and survival in liquid media solely consisting of packaging materials with different fiber types. We evaluated food contaminating species (, , ), two packaging material isolates and bacterial endospores for their growth abilities.

Modelling and Determination of Parameters Influencing the Transfer of Microorganisms from Food Contact Materials.

The transfer of microorganisms on packaging materials to a contact surface has only been investigated in the context of laboratory-produced spiked packaging products and agar surfaces in small quantities (0.03-0.10%) so far.

in Packaging Material: Molecular and Phenotypical Diversity Revealed.

The group has been isolated from soils, water, plants and numerous food products. These species can produce a variety of toxins including several enterotoxins [non-hemolytic enterotoxin (Nhe), hemolysin BL (Hbl), cytotoxin K, and enterotoxin FM], the emetic toxin cereulide and insecticidal Bt toxins. This is the first study evaluating the presence of in packaging material.

Comparison of Updated Methods for Detection in Environmental Water Samples.

The difficulty of cultivation of spp. from water samples remains a strenuous task even for experienced laboratories. The long incubation periods for make isolation difficult.
