Simulated Microgravity Accelerates Alloy Corrosion by Aspergillus sp. via the Enhanced Production of Organic Acids

Abstract

The space station and other long-term manned spacecrafts will experience the risk of microbial corrosion, especially mold, which will be harmful to the platform system and astronauts. Aspergillus sp. has been widely reported to produce organic acids that corrode and destroy materials, and the ability of these crafts to fly through space can be significantly affected. Research on the mechanism that causes enhanced corrosion ability of fungi in space stations is important to control their growth.

Mg–Al LDH nanosheets as a nanotechnological tool in agriculture: an exploratory toxicity evaluation study

“…The mechanism used by T. atroviride to take advantage of the nutrients from the nanoparticle for its growth is a topic that requires study; however, fungi are capable of bioabsorbing and/or biodegrading metal ions. 77 The metal ions are essential elements for the metabolic activity and optimal growth of fungi; for example, it was discovered that the absence of Mg produces significant delays in the cell cycle, low lipid yields, and decreased biomass production. 78 In this context, fungi could take advantage of the metal ions in Mg-Al LDH through various absorption mechanisms or intra or extracellular biodegradation for growth.…”

The microbial community of rust layer biofilm was driven by seawater microbial community

“…The production of organic acids by Aspergillus sp. has been extensively documented as having detrimental effects on various materials, leading to corrosion and destruction (38). The resilience of Aspergillus terreus in the face of organic carbon deficiency enables its ability to establish a biofilm on the surface of Aluminum alloys, thereby hastening the corrosion of aluminum alloys (24).…”
