Summary: We present a new production process for lactobionic acid (LBA) using an engineered Neurospora crassa strain F5. The F5 strain showed slower lactose utilization rate and higher production of cellobiose dehydrogenase (CDH) compared to the wild-type strain. The F5 strain produced CDH and laccase simultaneously in the presence of pretreated wheat straw and induced by cycloheximide. Direct addition of deproteinized cheese whey to shake flasks with the fungus led to LBA production, with a yield of approximately 85% from consumed lactose and a productivity of about 1.37 g/L/h.

Summary: Block freeze concentration (BFC) is an emerging technology that allows for the production of high-quality organoleptic products through low temperatures. This study investigated the effects of vacuum-assisted BFC on whey, specifically examining vacuum time, vacuum pressure, and initial solids concentration. The results showed significant impacts of these variables on solute yield and concentration index. By optimizing the conditions, it is possible to recover at least 70% of lactose in whey samples in a single step.

Summary: This study reported for the first time the co-crystallization of lactose with bioactive compounds (flavonoids) using cheese whey as a lactose source. The results showed successful encapsulation of flavonoids in lactose crystals, with an encapsulation efficiency of approximately 40%. The co-crystals exhibited stable antioxidant activity during storage and only slight decrease in IC50 values after UV light exposure.

Summary: This study investigated the changes in kinetics, yield, size and composition of lactose crystals in Panela cheese whey when acidified (pH 3.80) or slightly alkalinised (pH 6.89) before crystallisation. Acidification at pH 3.8 accelerated crystallisation and reduced the incorporation of salts and proteins in lactose crystals, but also resulted in the formation of amorphous lactose. On the other hand, at pH 6.89 and under stirring conditions, amorphous lactose was not formed and a high crystallisation yield (approximately 25 g of lactose per Kg of whey) with around 80% lactose recovery was achieved.

Summary: Native whey obtained during casein micelle microfiltration was used as a novel source to produce galacto-oligosaccharides (GOS). The effect of different ultrasound processing conditions on GOS synthesis using concentrated native whey was evaluated. At specific conditions, a high specific enzyme productivity similar to pure lactose was achieved, allowing for the production of prebiotic-containing products without the need for purification steps.

Summary: Valorization of by-products in the dairy industry is a priority worldwide to promote circular economies. This study demonstrates a process to produce galacto-oligosaccharides (GOS) from whey permeate, which can be used directly in daily dairy products. The results show high GOS yield and utilization, and improved flavor and mouthfeel in the final product.

Summary: A green methodology was introduced to convert cellulose directly into electrical power output using a cellulase complex and an enzymatic biofuel cell. The biofuel cell achieved a maximal operational lifetime of 32 hours under optimized conditions and generated electrical power of approximately 300-600 μW cm(-2) under different conditions. The one-pot biofuel cell allows bias-free electrical power generation with only cellulose and O2 required for operation.

Summary: This study analyzes the characteristics of process parameters in three lean gas ethane recovery processes and establishes a prediction and multiobjective optimization model for ethane recovery and system energy consumption. A new method for comparing ethane recovery processes for lean gas is proposed, and the addition of extra coolers improves the ethane recovery. The support vector regression model based on grey wolf optimization demonstrates the highest prediction accuracy, and the multiobjective multiverse optimization algorithm shows the best optimization performance and diversity in the solutions.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.

Summary: This study uses survey data from the Loess Plateau in China to evaluate the impact of social interaction on the adoption of soil and water conservation (SWC) technology by farmers. The study finds that social interaction increases the likelihood of farmers adopting SWC, and internet use moderates this effect. The positive impact of social interaction on SWC adoption is more pronounced for farmers in larger villages and those who join cooperative societies.
