Special Issue Information

Dear Colleagues,

Heterogeneous surfaces, especially those with pores on the nanometer and submicrometer scale, affect the growth of microorganisms differently compared to homogeneous surfaces made of the same materials. There is a popular belief among scientists that nano surfaces have potential as antibacterial and bacteriostatic materials. Inverse situations where the growth of microorganisms favors rough (nano and submicrometer) surfaces compared to atomically smooth are less common but also observed. This fact shows that our knowledge of this phenomenon is still incomplete and describing it systematically would give us a powerful tool to control the microbes in our surroundings. This is of great importance due to the role of biofilms in bacterial infections and the production of chemicals using microbes (e.g., lactic acid and dextran). In this case, studying less-described phenomena, i.e., growth stimulation, may reveal new information to help understand the broader perspective.

This Special Issue welcomes the submission of original research works, as well as reviews, dealing with the modification of bacterial growth by well-characterized and defined surfaces. Topics should focus on correlating surface topology and the nature of growth modification. Works showing any effects related to pro-growth stimulation and less-common observations in the scientific literature are particularly welcome.

Growth of Lactic Acid Bacteria on Gold—Influence of Surface Roughness and Chemical Composition

The main focus of this work was to establish a correlation between surface topography and chemistry and surface colonization by lactic acid bacteria. For this reason, we chose gold substrates with different surface architectures (i.e., smooth and nanorough) that were characterized by atomic force microscopy (AFM), electron scanning microscopy (SEM), and X-ray diffractometry (XRD). Moreover, to enhance biocompatibility, we modified gold substrates with polymeric monolayers, namely cationic dextran derivatives with different molar masses. The presence of those layers was confirmed by AFM, infrared spectroscopy (IR), and X-ray photoelectron spectroscopy (XPS). In order to determine the adhesion abilities of non-modified and modified gold surfaces, we tested three lactic acid bacteria (LAB) strains (i.e., Lactobacillus rhamnosus GG, Lactobacillus acidophilus, and Lactobacillus plantarum 299v). We have shown that surface roughness influences the surface colonization of bacteria, and the most significant impact on the growth was observed for the Lactobacillus rhamnosus GG strain. What is more, covering the gold surface with a molecular polymeric film by using the layer-by-layer (LbL) method allows additional changes in the bacterial growth, independently on the used strain. The well-being of the bacteria cells on tested surfaces was confirmed by using selective staining and fluorescence microscopy. Finally, we have determined the bacterial metabolic activity by measuring the amount of produced lactic acid regarding the growth conditions. The obtained results proved that the adhesion of bacteria to the metallic surface depends on the chemistry and topography of the surface, as well as the specific bacteria strain. Full article
