“…The primary mechanism of metal accumulation by microbes is biosorption followed by bioaccumulation into the cells, controlled siderophore production, enhanced respiration and modified protein profile [55,56] Pseudomonas halodenitrificans efficiently biosorbed Co on its cell walls and the biosorption was significantly inhibited by the presence of divalent ions such as Ca [57]. Pseudomonas sp.…”

This study examined the influence of bioaugmentation on metal concentrations (aluminum, cadmium, chromium, cobalt, copper, iron, lead, manganese, molybdenum, nickel and zinc) in anaerobically digested sewage sludge. To improve the digestion efficiency, bioaugmentation with a mixture of wild-living Archaea and Bacteria (MAB) from Yellowstone National Park, USA, was used. The total concentration of all metals was higher in the digestate than in the feedstock. During anaerobic digestion, the percent increase in the concentration of most of metals was slightly higher in the bioaugmented runs than in the un-augmented runs, but these differences were not statistically significant. However, the percent increase in cadmium and cobalt concentration was significantly higher in the bioaugmented runs than in the un-augmented runs. At MAB doses of 9 and 13% v/v, cadmium concentration in the digestate was 211 and 308% higher than in the feedstock, respectively, and cobalt concentration was 138 and 165%, respectively. Bioaugmentation increased over 4 times the percentage of Pseudomonas sp. in the biomass that are able to efficiently accumulate metals by both extracellular adsorption and intracellular uptake. Biogas production was not affected by the increased metal concentrations. In conclusion, bioaugmentation increased the concentration of metals in dry sludge, which means that it could potentially have negative effects on the environment.

“…Despite its potential, progress in this method has been limited. This is primarily due to the high cost and scarcity of volatile and stable organometallic compounds. − Notably, cold plasma deposition allows for the precise deposition of nanometer-scale metal–organic compounds on organic biocompatible substrates.…”

Although metal−organic thin films are required for many biorelated applications, traditional deposition methods have proven challenging in preparing these composite materials. Here, a Co-organic composite thin film was prepared by plasma-enhanced atomic layer deposition (PEALD) with cobaltocene (Co(Cp) 2 ) on polydimethylsiloxane (PDMS), using two very high frequency (VHF) NH 3 plasmas (60 and 100 MHz), for use as a tissue culture scaffold. VHF PEALD was employed to reduce the temperature and control the thickness and composition. In the result of the VHF PEALD process, the Young's modulus of the Co-organic composite thin film ranged from 82.0 ± 28.6 to 166.0 ± 15.2 MPa, which is similar to the Young's modulus of soft tissues. In addition, the deposited Co ion on the Co-organic composite thin film was released into the cell culture media under a nontoxic level for the biological environment. The proliferation of both L929, the mouse fibroblast cell line, and C2C12, the mouse myoblast cell line, increased to 164.9 ± 23.4% during 7 days of incubation. Here, this novel bioactive Co-organic composite thin film on an elastic PDMS substrate enhanced the proliferation of L929 and C2C12 cell lines, thereby expanding the application range of VHF PEALD in biological fields.

“…However, these methods are expensive if relatively high concentrations of metals, such as 1-100 mg L −1 , are to be removed [7,9,10]. Furthermore, a major disadvantage of conventional treatment methods is the production of toxic sludge.…”

“…The cell walls of microbial biomass, mainly composed of polysaccharides, proteins and lipids, contain abundant metal-binding functional groups, such as carboxylate, hydroxyl, sulphate, phosphate and amino groups. Biosorption enables passive metal uptake by microbial biomass through processes such as complexation, ionexchange, physical adsorption and inorganic microprecipitation [9,12,13,15]. Several algae, bacteria, fungi and yeasts have been found to be effective metal sorbents [9,12].…”
