“…These acids have low reactivity, which makes the surface of mycobacteria waxy and extremely hydrophobic [ 74 ]. According to multiple studies, mycolic acids ensure the resistance of R. erythropolis to various stress factors and pollutants, such as oil products and heavy metals [ 75 , 76 , 77 , 78 , 79 ], and also allow survival on very poor nutrient media [ 80 ]. We assume that the presence of a negative effect of NCs on the viability of Cms is associated with the absence of mycolic acids in the cell wall of this bacterium.…”

New promising manganese-containing nanobiocomposites (NCs) based on natural polysaccharides, arabinogalactan (AG), arabinogalactan sulfate (AGS), and κ-carrageenan (κ-CG) were studied to develop novel multi-purpose trophic low-dose organomineral fertilizers. The general toxicological effects of manganese (Mn) on the vegetation of potatoes (Solanum tuberosum L.) was evaluated in this study. The essential physicochemical properties of this trace element in plant tissues, such as its elemental analysis and its spectroscopic parameters in electron paramagnetic resonance (EPR), were determined. Potato plants grown in an NC-containing medium demonstrated better biometric parameters than in the control medium, and no Mn accumulated in plant tissues. In addition, the synthesized NCs demonstrated a pronounced antibacterial effect against the phytopathogenic bacterium Clavibacter sepedonicus (Cms) and were proved to be safe for natural soil microflora.

“…are known to degrade PAHs (Wang et al, 2021 ), phthalates (Choi et al, 2005 ), and lignin (Bhatia et al, 2019 ). Rhodococcus erythropolis HX7 was isolated from Russian soil and is known to degrade oil (Novikov et al, 2021 ). Rhodococcus jostii RHA1 is a known phthalate and aromatic degrader and was used to identify the terephthalate degradation pathway (Hara et al, 2007 ).…”

Versatile microbial communities rapidly assimilate ammonium hydroxide-treated plastic waste

Most plastic waste accumulates in landfills or the environment. Natural microbial metabolisms can degrade plastic polymers. Unfortunately, biodegradation of plastics is slow even under ideal conditions; depolymerization of plastic is the rate limiting step. Rapid chemical depolymerization yields biodegradable plastic monomers, improving biodegradation rates. Here we demonstrate that ammonium hydroxide depolymerizes PET into terephthalic acid and terephthalic acid monoamide which are rapidly metabolized by diverse consortia obtained from compost and sediment. By neutralizing the product with phosphoric acid prior to bioprocessing, the final product contains plastic-derived carbon and biologically accessible nitrogen and phosphorus from the process reactants, removing the need for culture medium. Three microbial consortia were able to degrade chemically deconstructed PET in ultrapure water and scavenged river water without the addition of nutrients, with no statistically significant difference in growth rate compared to communities grown on deconstructed PET in Bushnell Haas minimal culture medium. The consortia were dominated by Rhodococcus spp., Hydrogenophaga spp., and many lower abundance genera. All taxa were related to species known to degrade aromatic compounds. Microbial consortia are known to confer flexibility in processing diverse substrates. To highlight the versatility of these consortia, we also demonstrate that two microbial consortia can grow on similarly deconstructed polyesters, polyamides, and polyurethanes in water instead of medium. Our findings suggest that using microbial communities enable flexible bioprocessing of mixed plastic wastes. We also demonstrate the flexibility of this approach for coupled chemical deconstruction and bioprocessing.
