Summary: This study investigated the peptidomic patterns of fermented milk by different strains of Lactobacillus delbrueckii ssp. bulgaricus and ssp. lactis before and after simulated gastrointestinal digestion. Variations in peptidomics were found among samples, with different subspecies displaying distinct peptide profiles. Digestion appeared to reduce peptidomics variations and the strain L. delbrueckii ssp. bulgaricus DQHXNS8L6 was the most efficient in generating bioactive peptides.

Summary: This study investigates the possibility of utilizing high GABA-producing Bifidobacterium adolescentis strains to produce fermented probiotic milks naturally enriched in GABA. In silico and in vitro analyses were conducted to evaluate their metabolic and safety traits as well as their survival in a simulated gastrointestinal passage. One strain, IPLA60004, showed better survival to lyophilization, cold storage, and gastrointestinal passage compared to other investigated strains. Fermentation with this strain yielded milk drinks with the highest GABA concentration and viable bifidobacterial cell counts, achieving conversion rates of the precursor, monosodium glutamate (GMS), up to 70%. This is the first report on the elaboration of GABA enriched milks through fermentation with B. adolescentis.

Summary: This study found that antibiotic treatment leads to dysbiosis of the gut microbiota in mice, which in turn affects bone development and bone density. On the other hand, probiotic treatment promotes fracture healing in osteoporotic mice after dysbiosis, potentially through inhibiting the RAS/RANKL/RANK pathway.

Summary: This study investigated the application of Bifidobacterium longum CCFM5871 as an adjunct starter culture for the production of fermented milk. Genome analysis revealed that CCFM5871 possesses various carbohydrate metabolic pathways, and comparative genomic analysis showed similar functional genes in other bifidobacteria strains used in dairy fermentation. The results demonstrated that supplementation with CCFM5871 increased acidification and solidification of fermented milk, without significantly affecting flavor and taste compared to the control group.

Summary: This study used non-targeted metabolomics technology to analyze the metabolic profile of fermented milk beverages (FMB) co-fermented by Bifidobacterium animalis subsp. lactis ProbioM8 and Lacticaseibacillus paracasei PC-01 over a 21-day period. Comparative analysis revealed 21 discriminatory metabolites and enrichment in key metabolic pathways during and after storage. The metabolic profile of FMB after 21-day storage differed significantly from shorter storage durations, containing more health-promoting metabolites. This study provides valuable information on post-fermentation changes in fermented dairy milk products.

Summary: The study investigated seven strains of lactic acid bacteria isolated from breast milk for their probiotic properties. Lactobacillus plantarum 5H1 and 5L1 were chosen for their beneficial characteristics and utilized in the production of probiotic fermented milk. The findings demonstrated the antimicrobial activity of the strains against pathogenic bacteria and toxigenic fungi, as well as their ability to adhere and reduce Salmonella adhesion to Caco-2 cells. During milk fermentation, an increase in lactic acid content, decrease in milk pH, and rise in total bacterial count were observed, while LAB viability in fermented milk storage remained at around 8 log10 CFU/mL.

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: The production of cement contributes to climate imbalance by emitting 5 to 7% of global carbon dioxide emissions. Biotechnology offers a solution by cultivating bacteria and fungi to synthesize calcium carbonate as a main component of cement. Bioconcrete can be delivered to concrete cracks through biomineralization and crystallization, assisted by microencapsulation that determines when crystallization is needed. This review explores the composition of Portland cement, analysis methods, deterioration, and the environmental and energetic benefits of using bioconcrete, as well as discussing the concept of carbon credits. The findings strengthen the potential of self-healing concrete in meeting the high demand for concrete and building a sustainable society.

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.

A lab-scale batch reactor was used to optimize the reaction using advanced oxidation process (AOP) with hydrogen peroxide as the oxidizing agent. A maximum total organic carbon (TOC) conversion of 63% was achieved. The kinetic modeling of the oxidation process provides valuable information for in situ seawater treatment and reducing ocean contamination caused by offshore oil and gas exploration.

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.
