The main aim of this study was to utilize naturally selected Pseudomonas putida strains isolated from activated sludge in a wastewater treatment plant, for the purpose of bioremediation of biogas effluent to remove organic content and color. Biogas effluent from anaerobically digestion of distillery wastewater treated with P. putida at the best evaluated condition (sample concentration of 50% v/v, agitation and aeration rates of 250 rpm and 1.0 vvm for 6 days) showed significant decolorization and organic removal efficacies of 34.29 ± 0.87% and 38.94 ± 0.63%, respectively. Bioremediation efficiency was dependent on bacterial growth which organic content in sample and dissolved oxygen during cultivation were key factors. The natural selected bacterium could tolerate higher organic content and work synergistically with other indigenous microorganisms found in the biogas effluent. Consequently, bioremediation of biogas effluent by natural selected P. putida is feasible to apply in biogas power plant where sterilization is not necessary in the process. © 2023, The Authors.

The study investigated the potential of wastewater-derived microalgae as a cost-effective feedstock for bioethanol production. The influence of CO2 loading, use of swine wastewater as a nutrient source, effect of micronutrients in the cultivation media, and scale-up of Chlorella vulgaris FSP-E was conducted. Results showed that 2% CO2, 25% swine wastewater, 500 mg/L sodium nitrate, 40 mg/L K2HPO4, 75 mg/L MgSO4, and 6 mg/L citric acid were optimal for maximal biomass production, nitrate removal, and carbohydrate accumulation in BG-11 medium. The maximum biomass and carbohydrate content obtained in this study were 35-fold and 60%, respectively. Scaling up to 5 L volume was challenging due to illumination, aeration, and mixing issues. The obtained carbohydrate-rich biomass was subjected to mild sulfuric acid hydrolysis and subsequently used for bioethanol fermentation. The hydrolysate was composed solely of glucose and galactose and was converted into bioethanol within 8 h by Saccharomyces cerevisiae with an ethanol yield of 0.22 ± 0.01 g ethanol per g biomass. Further exploration of effective lighting and mixing strategies are recommended to realize economically viable microalgal biofuels. © 2024 Elsevier Ltd

Future human spaceflight beyond low-Earth orbit will bring substantial changes and new requirements to the development of fully sustainable, healthy indoor human environments across a range of gravitational, radiative, and thermal conditions. One key aspect is understanding (and potentially leveraging) microorganisms that must coexist with humans, plants, and animals in enclosed habitats (their microbiota or microbiomes). Modern, genome-resolved microbiome science provides an opportunity to better understand how we can utilize microbes to optimize space missions and protect human health and well-being long-term. Microorganisms will be critical to mission success due to their direct or indirect interactions with 1) humans, 2) other living systems (e.g., plant and animal life as a food source and for experimentation), and 3) the built environment. For example, the human gut microbiome is a complex community that has important implications for human health and performance that include mental health, nutrition intake, and immune system function. The health of plant microbiomes is also critical for sustainable, dependable, and nutritious food production. Humans, plants, and other living systems (e.g., animals used in experimentation) will also shed microbes into the built environment, which may impact human exposure, plant health, system integrity, and planetary protection from microbial contamination in both forward and reverse directions. Microbes from all three systems will interact, resulting in potentially important 'non-linear' system implications that must be understood for the overall long-term sustainability of hardware, crew, and other living systems. This paper discusses recent advances in technology that expand measurement capabilities to ultra-low-biomass samples and now allow for better understanding of microbial taxa, community structure and drivers, and functional capacity, which together will empower microbiome-optimized deep-space human exploration miss

Background The removal of hazardous dyes from water by magnetic adsorbents has received significant interest due to their low cost and ease of separation from the solution phase. This study explores the efficacy of a novel hybrid adsorbent, magnetite and activated charcoal-modified MgAl layered double hydroxide (MgAlLDH@MAC), for removing congo red (CR) from aqueous solutions. Methods MgAlLDH@MAC was successfully prepared via a co-precipitation to hydrothermal method and characterized using FE-SEM, FE-STEM, VSM, BET, XRD, FTIR, XPS, and HPLC analysis. Significant findings The incorporation of magnetite and activated charcoal was successful, resulting in excellent adsorption performance for CR and easy separation from the solution due to its magnetic properties. The adsorbent achieved a maximum adsorption capacity of 625 mg/g, which is in line with the Langmuir isotherm and pseudo-second-order kinetic model. Moreover, the adsorbent demonstrated excellent stability and reusability, retaining 91.78% efficiency after five adsorption-desorption. This study offers a fresh viewpoint on creating high-performance LDH adsorbents that remove dyes quickly and effectively using carbon and magnetite materials. © 2024, The Authors.

Evapotranspiration is an important parameter to evaluate soil water deficit and water use efficiency, especially at places with irregularly distributed precipitation. The aim of this study was to assess the daily actual evapotranspiration (ETa) estimated by the Thornthwaite and Mather soil water balance method adapted for crops (ThM) and by the dual Kc approach with the crop coefficients optimized from inversing modeling and by the adjustment procedure suggested in FAO-56. The models comparison and optimization were performed with actual evapotranspiration determined by the Bowen ratio – energy balance method (ETβ) for sugarcane at full canopy closure grown in Alagoas State, Northeastern Brazil. The objective function of the inverse problem was defined in terms of ETβ and ETa estimated by the ThM and dual Kc method by optimizing single crop coefficient (Kc) and the basal coefficient Kcb, respectively. Both optimized Kc and Kcb were lower than the adjusted Kc FAO56, with optimized Kc only 3% less than the Kc obtained experimentally. ETa estimated by ThM and dual Kc models with optimized crop coefficients (Kc = 1.05 or Kcb = 1.00) had similar high precision (r2 > 0.79) and accuracy (dm > 0.93 and RMSE -1), whereas using the coefficients derived from FAO 56 overestimated ETa in both models. © 2021, CC BY.

General framework for the mechanical response of metallic glasses during strain-rate-dependent uniaxial compression

Experimental data on compressive strength σmax versus strain rate ɛ̇eng for metallic glasses undergoing uniaxial compression show varying strain rate sensitivity. For some metallic glasses, σmax decreases with increasing ɛ̇eng, while for others, σmax increases with increasing ɛ̇eng, and for certain alloys σmax versus ɛ̇eng is nonmonotonic. To understand their strain rate sensitivity, we conduct molecular dynamics simulations of metallic glasses undergoing uniaxial compression at finite strain rates and coupled to heat baths with a range of temperatures T0 and damping parameters b. In the T0→0 and b→0 limits, we find that the compressive strength σmax versus temperature T obeys a “chevron-shaped” scaling relation. In the low-strain-rate regime, σmax decreases linearly with increasing T, whereas σmax grows as a power law with decreasing T in the high-strain-rate regime. For T0>0, σmax(T) deviates from the scaling curve at low strain rates, but σmax(T) rejoins the scaling curve as the strain rate increases. Enhanced dissipation reduces compression-induced heating, which causes σmax(T) to deviate from the b→0 scaling behavior for intermediate strain rates, but σmax(T) converges to the high-strain-rate power-law scaling behavior at sufficiently high strain rates. Determining σmax(T) as a function of b and T0 provides a general framework for explaining the strain rate sensitivity of metallic glasses under compression.

This study delves into the evaluation of the Komodo dragons Adaptive Conservation program (KACP) at Komodo National Park in Indonesia through Importance-Performance Analysis (IPA). It aims to understand how the programs components align with community priorities and assess its effectiveness. Utilizing a mixed-methods approach, this research analyzes community perceptions of KACP's critical elements, spanning eco-tourism initiatives to environmental protection strategies. The community is categorized into local advocates, eco-tourism enthusiasts, and eco-community harmonizers, identifying how each group perceives and interacts with various facets of KACP. The findings reveal significant differences in perceptions of importance and performance among these groups, providing insights into areas of strength and those needing improvement. Additionally, the study includes an analysis of demographic influences on these perceptions through Logit and Probit models, aiming to understand the impacts across different community segments. The results highlight the necessity for an adaptive and responsive design in conservation efforts, considering community expectations and ecological impacts. Despite offering comprehensive insights, the study acknowledges limitations in the demographic scope and suggests future research directions, such as longitudinal studies and an expanded analysis of variables. These findings offer critical guidance for policymakers and conservation practitioners to enhance conservation programs’ effectiveness and community alignment, emphasizing the need to adapt to the challenges and changes introduced by KACP. © 2024 Elsevier GmbH

Cellular metabolism is dynamic, but quantifying non-steady metabolic fluxes by stable isotope tracers presents unique computational challenges. Here, we developed an efficient 13 C-tracer dynamic metabolic flux analysis (13C-DMFA) framework for modeling central carbon fluxes that vary over time. We used B-splines to generalize the flux parameterization system and to improve the stability of the optimization algorithm. As proof of concept, we investigated how 3T3-L1 cultured adipocytes acutely metabolize glucose in response to insulin. Insulin rapidly stimulates glucose uptake, but intracellular pathways responded with differing speeds and magnitudes. Fluxes in lower glycolysis increased faster than those in upper glycolysis. Glycolysis fluxes rose disproportionally larger and faster than the tricarboxylic acid cycle, with lactate a primary glucose end product. The uncovered array of flux dynamics suggests that glucose catabolism is additionally regulated beyond uptake to help shunt glucose into appropriate pathways. This work demonstrates the value of using dynamic intracellular fluxes to understand metabolic function and pathway regulation.
