“…[38][39][40] Positive value of ΔH° (22.42 kJ/kmol) shows the endothermic nature of the adsorption. This fact indicates the possibility of physical adsorption, since the heat of chemisorption generally falls into a range of 80-200 kJ/mol.…”

The adsorption of malachite green (MG) from aqueous solution by waste green tea (WGT) biomass was investigated. A series of experiments in batch conditions were conducted in order to assess the MG removal on WGT, following adsorbent quantity and temperature influences. Maximum removal efficiency for untreated WGT was 89% (4 g biomass, 100 mL solution of 94 mg/L, 316 K). It was found that the adsorption of MG increased by increasing temperature from 296 to 316 K. Thermodynamic parameters (ΔH°, ΔS°, ΔG°) were calculated, and indicated that dye adsorption onto the studied biomass was endothermic and non-spontaneous. Six chemical treatments were tested (four acidic -H 3 PO 4 , H 2 SO 4 , HCl, and tartaric acid, one oxidant -H 2 O 2 , and one basic -NaOH) in order to study the chemical groups responsible for MG adsorption onto WGT biomass. The alkali and acidic treatments led to an increase of adsorption efficiency up to 92% and 95% (H 2 SO 4 ) respectively. The FTIR spectroscopy results emphasized the modifications of the biomass surface and how these are influencing the adsorption process.

“…hispanica is capable to grow on acetate as a sole carbon source and possesses a gene cluster for the methylaspartate cycle enzymes, similar to H. marismortui (Figure 2; Juez et al, 1986;Liu et al, 2011b;Ding et al, 2014). In this study, we used deletion mutants of H. hispanica to prove the participation of the key enzymes of the methylaspartate cycle in acetate assimilation.…”

The methylaspartate cycle in haloarchaea and its possible role in carbon metabolism

et al. 2015

Haloarchaea (class Halobacteria) live in extremely halophilic conditions and evolved many unique metabolic features, which help them to adapt to their environment. The methylaspartate cycle, an anaplerotic acetate assimilation pathway recently proposed for Haloarcula marismortui, is one of these special adaptations. In this cycle, acetyl-CoA is oxidized to glyoxylate via methylaspartate as a characteristic intermediate. The following glyoxylate condensation with another molecule of acetylCoA yields malate, a starting substrate for anabolism. The proposal of the functioning of the cycle was based mainly on in vitro data, leaving several open questions concerning the enzymology involved and the occurrence of the cycle in halophilic archaea. Using gene deletion mutants of H. hispanica, enzyme assays and metabolite analysis, we now close these gaps by unambiguous identification of the genes encoding all characteristic enzymes of the cycle. Based on these results, we were able to perform a solid study of the distribution of the methylaspartate cycle and the alternative acetate assimilation strategy, the glyoxylate cycle, among haloarchaea. We found that both of these cycles are evenly distributed in haloarchaea. Interestingly, 83% of the species using the methylaspartate cycle possess also the genes for polyhydroxyalkanoate biosynthesis, whereas only 34% of the species with the glyoxylate cycle are capable to synthesize this storage compound. This finding suggests that the methylaspartate cycle is shaped for polyhydroxyalkanoate utilization during carbon starvation, whereas the glyoxylate cycle is probably adapted for growth on substrates metabolized via acetyl-CoA.

TaCNbC with and without the addition of 5 vol.% B 4 C and 5 vol.% Si nano-powders as sintering aids were consolidated by spark plasma sintering at 1850°C. The effect of sintering aid addition on the densification and mechanical properties is evaluated along with secondary phase formations. Relative density >99% is achieved with a hold time of just 3 min for the addition of Si and 10 min for the addition of B 4 C as sintering additives. High load instrumented indentation was performed and projected area of residual damage is compared to estimate relative fracture toughness. The addition of 5 vol.% Si as a sintering additive resulted in a 46% reduction in projected residual damage area and 14.5% more energy dissipation during indentation than the sample with 5 vol.% B 4 C as the sintering additive resulting in a higher overall toughness.
