#2The stats on this look good.
Do any biochemists have notes that would point to it being or not being worthwhile?

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 predominantly hindered by the economics, including high labor costs, expensive inputs, and slow processing times.
Hopefully in the future we can dump a bunch of used brewers yeast into a giant gold tailings pond and leech gold and other precious metals for cheap, but we're not there yet.

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, fluidized bed bioreactors, textile industry, metal smelting, petrochemicals, paper manufacturing, and electrolysis applications.
The heavy metal contaminated wastewater finds its way into the environment, threatening human health and the ecosystem. The heavy metals are non-biodegradable1 and could be carcinogenic; thus, the presence of these metals in water by improper amounts could result in critical health issues to living organisms.
