Summary: The study evaluated the ability of Rhodovulum sulfidophilum DSM-1374 to convert certain organic acids into polyhydroxyalkanoate accumulations via a photo-fermentative process. Succinate was the most productive carbon source for P3HB synthesis, while acetate and lactate also produced significant amounts of polymer. By growing the bacterium in two steps, the cumulative P3HB production significantly increased, with lactate under phosphorus starvation showing the highest P3HB accumulation.

Summary: This study investigated the effect of a new draw solution produced from microalgae Spirulina platensis on the biofouling mechanism of forward osmosis (FO) membrane. The use of higher draw solution concentrations led to a decline in water flux due to the accumulation of fouling layer on the membrane, which reduced the effective osmotic pressure difference. Different cleaning strategies were examined, and the efficacy and amount of foulant removed by each cleaning stage were assessed using scanning electron microscopy and energy dispersive X-ray spectroscopy.

Summary: The present study investigates the optimal control of the photosynthetic growth process in an artificial light photobioreactor operated in batch mode. By using a simple and reliable model for the photosynthetic growth of microalgae, predictions can be made on the quantity of produced biomass and on the amount of light consumed. An improved objective function is proposed and a closed-loop control structure has been designed based on the developed optimization algorithm. The optimal controller has been validated in simulation.

Summary: An induced pre-saturation tower (IPST) for oil-water separation was built on a semi-industrial scale, based on results obtained on a laboratory scale prototype. The efficiency of the bench scale prototype was increased by using a biosurfactant as an auxiliary collector. The validation of the developed criteria allowed the construction of an IPST with three stages, all fed with previously saturated effluents.

Summary: Assets deteriorate over time due to various factors, and maintenance can only prolong their useful life to a certain extent. This study proposes a new methodology for estimating the remaining useful life (RUL) of assets, which considers multiple criteria to maximize asset value throughout its lifecycle. The experimental results with real datasets demonstrate the effectiveness of this approach. Additionally, an analytical tool has been developed to optimize asset renewal decisions using the proposed RUL estimation methodology, with its application to the Brazilian electric sector.

Summary: Efficient policies for forecasting electricity demand are crucial for ensuring continuous energy supply. However, the selection of independent variables remains an unresolved issue. This study proposes a model that integrates a multi-criteria approach and artificial neural networks to forecast electricity demand in different countries, considering the specificities of each application. The results show that including variables selected by the multi-criteria approach improves the forecasting performance of artificial neural networks compared to traditional linear models, with Radial Basis Function Networks and Extreme Learning Machines being potential techniques to enhance the forecasting.

Summary: In this study, surfactant-rich extracts from quinoa, soybean, and acerola were evaluated for their stability, antioxidant capacity, toxicity potential, and cleaning potential in shampoo formulations. The extracts remained stable under different temperature and pH conditions, exhibited antioxidant properties, and showed low or no toxicity in irritation tests. The extracts also demonstrated effective cleaning ability as primary surfactants in shampoo formulations. Seven shampoo formulations were developed, meeting standard requirements and having comparable or better sebum removal capacity than a commercial shampoo.

Summary: Raw date palm waste was found to be an effective and environmentally friendly adsorbent for removing tetracycline and ciprofloxacin from water. The study examined the influence of various factors such as pH, biosorbent dose, antibiotic concentration, contact time, temperature, and salt concentrations. The pseudo-second-order model was the most suitable for describing the experimental data, and Langmuir and Dubinin-Radushkevich isotherms were found to be the best for TC and CIP adsorption, respectively. Thermodynamic parameters indicated that the process was spontaneous and endothermic.

Summary: In order to ensure the performance of the electrical system, the Brazilian national electricity system operator requires at least two power supplies for the AC auxiliary systems of the Electric substations (ESS), and an emergency generator (EG) to supply energy to essential loads in case of failure of these sources. To improve the availability of auxiliary systems, a microgrid with photovoltaic systems and Battery Energy Storage Systems (BESS) can be considered. This study focuses on the economic optimization of the PV/BESS system, taking into account the costs of equipment installation and maintenance, as well as the gains from the credits generated by the photovoltaic system in the net metering scheme, aiming to achieve a null total cost.

Summary: Small-scale wind turbines are important in distributed generation as they allow customers to produce electric energy using their own properties. The development of power electronics systems for small-scale wind turbines is a concern due to the need to balance cost, simplicity, efficiency, and performance. This paper presents the results of testing a three-phase phase-modular single-ended primary-inductance converter rectifier for processing the energy of a small-scale wind turbine system. The rectifier was able to process the non-sinusoidal three-phase system of the wind turbine and showed advantages such as using the generator's inductance as input filter inductor and simplicity of control.

Summary: This study compares the performance of a nanofiber device and a resin column for antibody capture. The nanofiber device has a larger housing volume and lower binding capacity, but comparable eluate purity to the resin column. It shows high stability, can be used for multiple cycles, and maintains consistent eluate quality when scaled up. The use of a single nanofiber device can significantly reduce costs compared to a resin column, especially when the number of batches is limited.

Summary: Fed-batch cell culture processes are commonly used in biomanufacturing due to their simplicity and applicability in cGMP environments. However, the challenge lies in the changing physiochemical conditions within the bioreactor as the cell density changes. Traditional response surface models (RSMs) are commonly used for optimization but are limited by their use of time-invariant factors. Dynamic RSM (DRSM) models can predict the time-dependent impact of process inputs, allowing for optimization of process operations that change over time.

Summary: Water for injection (WFI) production in the biopharmaceutical industry consumes excessive amounts of water and energy. Recycling buffers can potentially save up to 90% of resources, but achieving the full theoretical potential is impossible when a risk-aware design is used.

Summary: In this study, heterologous expression and homologous overexpression of ABC transporter proteins AatA and MdlB were found to improve butyric acid production in C. tyrobutyricum. The overexpression of these proteins upregulated the expression levels of key enzymes in the acetate synthesis pathway and promoted the synthesis and secretion of acetic acid. Additionally, the increase in ATPase activity facilitated sugar utilization, induced extracellular secretion of acetate, and shortened fermentation periods.
