“…In our study, magnetic field transmitted by high voltage line was not found to have any effect on the number of bacteria. Unlike our study, in a study conducted by Nascimento et al, (2003), a significant increase was found in the growth rate and glucose consumption of E. coli bacteria exposed to electromagnetic field in laboratory medium. Al-Khaza'leh and Al-Fawwaz (2015) researched the effect of magnetic field on the growth rate of three different bacteria strains (E. coli, Staphylococcus aureus and Bacillus subtilis).…”

The aim of this study is to find out whether there is chemical and microbiological degradation in the samples taken from fresh water sources near and far from high voltage lines. The samples were taken from Erfelek Meydan Village location Karasu River, Ayancık Tevfikiye Village location Zindan Brook, Ayancık Türkeli road junction Ayancık Brook, Durağan Yalnız Kavak location Gökırmak Water, Durağan-Boyabat Yalnız Kavak location Gökırmak water and Boyabat Sinecan Village location Kırkgeçit Brook in Sinop province of Turkey. Na + , K + , Cl-, pH and conductivity analysis were conducted chemically, while microbiological tests were made against Escherichia coli and coliform bacteria. All the results obtained were assessed according to 06.07.2019 dated and 30823 numbered 'Legislation on the quality and treatment of water from which drinking water is obtained' in T. C. Official Gazette. With this study, it can be said that high voltage lines in the province of Sinop do not have a significant effect on fresh water sources. Na + , K + , Clgave results in expected levels and conductivity gave results directly proportional to pH. In microbiological test results, Escherichia coli and coliform bacterial growth was found, while no microbiological degradation was found.

“…This behavior under stress conditions could also explain the high glucose consumption rate by K. xylinus when growing in the presence of chloramphenicol. Concerning the increase of K. xylinus glucose consumption under the effect of a magnetic field, it has been mentioned that this factor has a positive effect on bacterial growth [ 44 ]. The cause of this result can be explained by an increase of glucose entering through the cell membrane as a consequence of the stimulated transport system, as well as by shortening of the lag phase and excitement of the log phase.…”

In Vivo Modification of Microporous Structure in Bacterial Cellulose by Exposing Komagataeibacter xylinus Culture to Physical and Chemical Stimuli

et al. 2022

Bacterial cellulose (BC) samples were obtained in a static culture of K. xylinus under the effect of a low-intensity magnetic field, UV light, NaCl, and chloramphenicol. The effect of such stimuli on the amount of BC produced and its production rate, specific area, pore volume, and pore diameter were evaluated. The polysaccharide production was enhanced 2.28-fold by exposing K. xylinus culture to UV light (366 nm) and 1.7-fold by adding chloramphenicol (0.25 mM) to the medium in comparison to BC control. All the stimuli triggered a decrease in the rate of BC biosynthesis. BC membranes were found to be mesoporous materials with an average pore diameter from 21.37 to 25.73 nm. BC produced under a magnetic field showed the lowest values of specific area and pore volume (2.55 m2 g−1 and 0.024 cm3 g−1), while the BC synthesized in the presence of NaCl showed the highest (15.72 m2 g−1 and 0.11 cm3 g−1). FTIR spectra of the BC samples also demonstrated changes related to structural order. The rehydration property in these BC samples is not mainly mediated by the crystallinity level or porosity. In summary, these results support that BC production, surface, and structural properties could be modified by manipulating the physical and chemical stimuli investigated.

“…This can affect ion transport into the cells and this can result in biological changes in the organisms [6]. The other possible effects are the formation of free radicals due to magnetic field exposure [3] in addition to other main effect is the influence of electromagnetic fields on carbohydrate metabolism [7,19,20]. [20] also reported differences in cDNAfingerprints between cells exposed to magnetic fields and unexposed cells, and showed that the magnetic field induced changes in gene expression.…”

In vitro, inhibitory effects of static magnetic fields in the type of two poles and negative and positive pole on some virulence factors belong to C.albicans as pathogenic microorganism was investigated in this study. According to the findings of this study static magnetic fields in the type of two poles and negative pole displayed a variable degree of inhibitory effects against this microorganism via its virulence factors such as: germ tube formation, adhesion ability and biofilm formation in which negative pole showed more strongly effect than two poles as inhibitory values ranged from 35% as germination ability, 30% adhesion ability after 3hrs of treatment and 2.2mg/disk dry weight as biofilm formation after 72hrs of treatment compared with the inhibitory values for two poles ranged from 30% as germination ability, 25% adhesion ability after 3hrs of treatment and 2.7mg/ disk dry weight as biofilm formation after 72hrs of treatment . Following our earlier demonstration, the effects of positive pole also investigated in this study as 10 % for germination ability, 10% adhesion ability after 3hrs of treatment and 3mg/ disk dry weight as biofilm formation after 72hrs of treatment. These results revealed that static magnetic fields in the type of negative pole may be useful as antifungal agent against Candida albicans.
