TLDR
Exposure of Penicillium notatum to ionized air reduces the production of penicillin and growth of the mycelium and germination of spores also are depressed, but positive ions exert a greater effect than negative ions on spore germination.Abstract:
Exposure of Penicillium notatum to ionized air reduces the production of penicillin, negative ions exerting a greater effect than positive ions. Growth of the mycelium and germination of spores also are depressed, but positive ions exert a greater effect than negative ions on spore germination. Production of carbon dioxide is depressed to about the same extent as mycelial growth.read more

Biological impact of small air ions
TL;DR: It is shown that mice and rats display a charge-related metabolic response to air ions and this phenomenon also occurs in humans, and ion depletion is a constant concomitant of modern urban life, one reasonably may speculate about comparable inimical effects on humans.

A Model of Plasma-Biofilm and Plasma-Tissue Interactions at Ambient Pressure
Chen Chen,Dingxin Liu,Zhichao Liu,Aijun Yang,Hailan Chen,Gilbert Shama,Michael G. Kong,Michael G. Kong +7 more
TL;DR: In this paper, the authors present a model framework for plasma-biofilm and plasma-tissue interactions that can link molecular simulation of plasma chemistry to functions at a cell population level or a tissue level.

Negative Air Ions and Their Effects on Human Health and Air Quality Improvement.
TL;DR: A comprehensive reviewing on the effects of NAIs on humans/animals, and microorganisms, and plant development and the plant-based NAI release system under the pulsed electric field (PEF) stimulation is carried out.

TL;DR: The results of the study suggest that the bactericidal action attributed to negative air ions by previous researchers may have been overestimated.

Air pollution and microbial ecology
Harvey Babich,Bruce Lighthart +1 more
TL;DR: A detailed review of the literature pertaining to the interactions of and interrelationships between atmospheric pollution and microorganisms is presented in this paper, which is composed in such a manner as to stress the effects of pollution upon microbial ecology.

The effects of air ions on the living mammalian trachea
Albert P. Krueger,Richard Smith +1 more
TL;DR: Studies on the effects of air ions on the functional efficiency of the extirpated tracheal strip have been extended to the trachea of the living rabbit, rat, and mouse.

The action of air ions on bacteria. I. Protective and lethal effects on suspensions of Staphylococci in droplets.
TL;DR: In smog-contaminated atmospheres moderate concentrations of positive and negative air ions exerted a protective effect on staphylococci by delaying the drop in pH customarily observed and by diminishing the rate of evaporation.
Journal ArticleDOI
Effects of unipolar air ions on microorganisms and on evaporation
TL;DR: In this article, the authors used micro-chemical equipment and bacteriological techniques to study the effect of air ions on staphylococci and found that survival in clean and contaminated air was attributed to the action of contaminants in shielding the staphyclococci from high mobility ions.
