“…So the influence of MFs on organisms may depend on different magnetic field types and intensities, action times, and the variability of cell structures [ 57 , 58 ]. This complexity may be one of the reasons for the consistent controversy of the effect of MF is positive or negative on various microorganisms [ 59 ].…”

The effects of a static magnetic field (SMF) on Monascus ruber M7 (M. ruber M7) cultured on potato dextrose agar (PDA) plates under SMF treatment at different intensities (5, 10, and 30 mT) were investigated in this paper. The results revealed that, compared with the control (CK, no SMF treatment), the SMF at all tested intensities did not significantly influence the morphological characteristics of M. ruber M7, while the intracellular and extracellular Monascus pigments (MPs) and extracellular citrinin (CIT) of M. ruber M7 were increased at 10 and 30 mT SMF but there was no impact on the MPs and CIT at 5 mT SMF. The transcriptome data of M. ruber M7 cultured at 30 mT SMF on PDA for 3 and 7 d showed that the SMF could increase the transcriptional levels of some relative genes with the primary metabolism, including the carbohydrate metabolism, amino acid metabolism, and lipid metabolism, especially in the early growing period (3 d). SMF could also affect the transcriptional levels of the related genes to the biosynthetic pathways of MPs, CIT, and ergosterol, and improve the transcription of the relative genes in the mitogen-activated protein kinase (MAPK) signaling pathway of M. ruber M7. These findings provide insights into a comprehensive understanding of the effects of SMF on filamentous fungi.

“…The consequence is the ability of microbial activation and regulation of biological processes, resulting in improved quality of the agricultural environment and, consequently, of crops. According to Beretta et al (2019), the results support the possibility of using this technology on a large scale although evaluations regarding the effects of the use of different electromagnetic scales on microbial activity are scarce. The different agricultural practices, usually used in production systems, directly interfere in the growth and multiplication of arbuscular mycorrhizal fungi in the soil and in their symbiosis with the plant.…”

Agriculture is considered to be one of the most vulnerable sectors to climate-change. Crop production, particularly in tropical regions is facing increasing stresses due to natural and anthropogenic factors. Increased incidence of abiotic and biotic stresses has become a major cause for stagnation of productivity in main crops. There is evidence of yield declines in crops in many parts of the world due to increasing water stress, reduction in number of rainy days and increased air temperature. The symbiosis between arbuscular mycorrhizal fungi and plants has been studied for many decades. This symbiosis is recognized as the interaction with the greatest economic impact on agriculture due to the reduction of environmental stresses. The effects of mycorrhization on plants grown under heat stress conditions and the effect of Penergetic technology in increase of the mycorrhization percentage was evaluated in this study. It was observed that plants in symbiosis with mycorrhizae showed greater tolerance to heat stress and that the use of Penergetic in the crops enabled a significant increase in the mycorrhization percentage and it promove to be efficient to improve the conditions of maintenance and productivity of plants under stress conditions.

“…Evaluating the development of plant tissue in tissue culture with the presence of so-called "biofields" or regulated electromagnetic energy, Nayak et al (2018) observed an increase in plant development in the order of 68% when using different frequencies of biofields. Similar results were also observed by Mihaela et al (2006) Increases in microbial growth have also been reported, demonstrating effects on acceleration of substrate consumption kinetics, increased resistance to soil pollutants, microbial biomass, metabolic activity or specific enzymes, increased metabolic activity or respiration rate, variation ATP concentration, alterations in cellular proteome, alterations in DNA / RNA synthesis and related activities, variations in transposition and production of secondary metabolites, increased cell hydrophobicity and adhesion between bacterial cells (Alvarez et al 2006;Cellini et al 2008;Aslanimehr et al 2013;Fijalkowski et al 2013;Ahmed et al 2015;Beretta et al 2019). According to Bereta et al (2019), although evaluations regarding the effects of the use of different electromagnetic scales on microbial activity are scarce, the known results support the possibility of using this technology on a large…”

The advances in productivity and product quality observed in world agriculture lead to the use of new technologies capable of meeting current demands. The use of low frequency electromagnetic fields has shown significant results. In this context, the objective of this study was determine the effects of Penergetic technology on the direct stimulation of beneficial soil microorganisms under in vitro conditions. Mycelial growth and conidial formation of Trichoderma asperelloides, mycelial growth of ectomycorrhizal fungi Pisolithus microcarpus and Suillus sp. and the multiplication of bacterial cells of Bradyrhizobium japonicum species in culture medium with and without the addition of Penergetic. Significant increases in fungal and bacterial growth were observed when using the commercial biostimulator in culture medium. The use of sustainable technological tools represents a viable path because it consists of a solid and efficient management alternative capable of increasing the stimulus to biological development in the soil and, consequently, to agricultural productivity in an environmentally and sustainable safety.
