This is the first time I've seen the use of spent brewers yeast as the biomass for bioaccumulation. However, it falls short of addressing the economic feasibility of extracting the accumulated metals, an essential aspect for practical implementation. The ability of fungi to absorb metals is well-documented, but the real-world application of fungi for purposes such as bioaccumulation and bioremediation is predominantl…

Extracting metals would be a bonus, removing them from wastewater and concentrating them in a mass that can be buried for later processing is boon enough for now. The presence of heavy metals in wastewater has been increasing with the growth of industry and human activities, e.g., plating and electroplating industry, batteries, pesticides, mining industry, rayon industry, metal rinse processes, tanning industry, flui…

You can as well just bury the microelectronics directly

The stats on this look good. Do any biochemists have notes that would point to it being or not being worthwhile?

am I the only one getting strong ChatGPT vibes here?

The first paragraph totally misses the point of any scientists discussion of this, which would center on the fraudulence level (esp. in a frontiersin-publication). Economic viability is important of course, but first results have to be robust...

That just leaves the bulk of the metals as toxic waste in water supplies; the metal compounds from: plating and electroplating industry, batteries, pesticides, mining industry, rayon industry, metal rinse processes, tanning industry, fluidized bed bioreactors, textile industry, metal smelting, petrochemicals, paper manufacturing, and electrolysis applications, etc.

Not disputing the potential ChatGPT, but I wouldn't harp on that top paragraph. The lab I work in does similar research (with inorganic materials) and virtually anything with anionic functional groups will work pretty effectively and more or less to the same degree. So the real question at this point is economic viability and local availability
