    Abstract A combined usage of animal and plant proteins-mixture could aid to solve environmental and social problems arising from the use of animal protein alone, while also improving the taste and texture of plant protein. Protein mixtures could be a better protein source due to the high availability of amino acids in the body compared with single proteins. Consuming proteins with probiotics can provide more beneficial health effects by helping to hydrolyze protein and absorb amino acids in the body. In this study, coadministration of an animal and plant protein mixture with a high concentration of probiotics was investigated to increase protein digestibility and amino acids absorbability in a mice model. Lactiplantibacillus plantarum IDCC 3501, which has the maximum ability to hydrolyze a protein mixture, composed of soybean protein and milk protein, was selected, and the changes in mice (C57BL/6J, male, six weeks) were investigated after the coadministration of protein mixture and 5 × 10⁸ or 5 × 10⁹ CFU/mL of L. plantarum for eight weeks. Normal diet, high-protein diet (HPD), and HPD supplementing L. plantarum were separately administered to mice. Food and water consumption of the mice did not differ depending on diet type. Measurements of the serum concentrations of amino acids showed that the absorption of aspartate, glutamate, isoleucine, leucine, valine, and lysine increased when high concentrations of protein and probiotics were administered. Thus, high L. plantarum concentrations could be a protein diet supplementation to improve health by promoting the absorption of amino acids.

    Abstract The demand for plant-based proteins as alternative meat sources continues to increase because of environmental concerns, animal welfare, and religious reasons. However, plant-based proteins have low digestibility than real meat, which should be overcome. In the present study, the effect of co-administration of legumin protein mixture and the probiotic strain on plasma concentration of amino acids was investigated as a strategy of enhancement in protein digestion. First, the proteolytic activity of the four probiotic strains was compared. As a result, Lacticaseibacillus casei IDCC 3451 was identified as an optimal probiotic strain that efficiently digested the legumin protein mixture by forming the largest halo produced by proteolysis. Next, to investigate whether the co-administration of legumin protein mixture and L. casei IDCC 3451 could synergically improve digestibility, mice were fed either a high-protein diet or a high-protein diet with L. casei IDCC 3451 for 8 weeks. Compared to only in the high-protein diet only group, the concentrations of branched chain amino acids and essential amino acids were 1.36 and 1.41 times higher in the co-administered group, respectively. Therefore, co-supplementation of plant-based proteins with L. casei IDCC 3451 can be suggested to improve protein digestibility based on the this study.

    Abstract During motor learning, dendritic spines on pyramidal neurons (PNs) in the primary motor cortex (M1) undergo reorganization. Intriguingly, the inhibition from local somatostatin-expressing inhibitory neurons (SST-INs) plays an important role in regulating the PN plasticity and thus new motor skill acquisition. However, the molecular mechanisms underlying this process remain unclear. Here, we identified that the early-response transcription factor, NPAS4, is selectively expressed in SST-INs during motor learning. By utilizing in vivo two-photon imaging in mice, we found that cell-type-specific deletion of Npas4 in M1 disrupted learning-induced spine reorganization among PNs and impaired motor learning. In addition, NPAS4-expressing SST-INs exhibited lower neuronal activity during task-related movements, and chemogenetically increasing the activity of NPAS4-expressing ensembles was sufficient to mimic the effects of Npas4 deletion. Together, our results reveal an instructive role of NPAS4-expressing SST-INs in modulating the inhibition to downstream task-related PNs to allow proper spine reorganization that is critical for motor learning.

    Abstract Background: Ceramides are essential lipids in stratum corneum for skin permeability barrier function in that they retain the skin moisture and protect from the invasion of foreign pathogens. Previously, we demonstrated that ferment lysates of Lacticaseibacillus rhamnosus IDCC 3201 enhanced ceramide production in human epidermal keratinocytes. Furthermore, for comprehensive knowledge of this effect, in vitro experiments and multi-omics analysis were conducted to explore the underlying mechanisms.
    Aims: This study was designed to identify whether a cosmetic sample (i.e., Cera-Glow) containing the lysates improves the skin barrier function in clinical trials.
    Patients/methods: Twenty-four female participants (45.46 ± 9.78 years) had been enrolled in the transepidermal water loss (TEWL) measurement for 5 days and 21 female participants (50.33 ± 5.74 years) had undergone a skin hydration evaluation for 4 weeks. TEWL and skin hydration were evaluated using a Tewameter and the Epsilon Permittivity Imaging System, respectively. After applying the Cera-Glow sample, all participants recorded a satisfaction survey questionnaire (e.g., satisfaction, efficacy, and adverse reactions).
    Results: Application of Cera-Glow significantly improved transepidermal water loss induced by 1% (w/v) sodium lauryl sulfate (p < 0.05-0.01) and increased skin hydration (p < 0.01). Metabolic analysis suggested that Cera-Glow should contain beneficial gradients for skin barrier function. According to the questionnaire, most of participants were satisfied with the skin hydration improvement and efficacy of Cera-Glow.
    Conclusions: Cera-Glow, ferment lysates of Lacticaseibacillus rhamnosus IDCC 3201, can significantly improve skin barrier function.

    Abstract The use of dietary protein products has increased with interests in health promotion, and demand for sports supplements. Among various protein sources, milk protein is one of the most widely employed, given its economic and nutritional advantages. However, recent studies have revealed that milk protein undergoes fecal excretion without complete hydrolysis in the intestines. To increase protein digestibility, heating and drying were implemented; however, these methods reduce protein quality by causing denaturation, aggregation, and chemical modification of amino acids. In the present study, we observed that

    Abstract As a renewable energy from biomass, isobutanol is considered as a promising alternative to fossil fuels. To biotechnologically produce isobutanol, strain development using industrial microbial hosts, such as Escherichia coli, has been conducted by introducing a heterologous isobutanol synthetic pathway. However, the toxicity of produced isobutanol inhibits cell growth, thereby restricting improvements in isobutanol titer, yield, and productivity. Therefore, the development of robust microbial strains tolerant to isobutanol is required. In this study, isobutanol-tolerant mutants were isolated from two E. coli parental strains, E. coli BL21(DE3) and MG1655(DE3), through adaptive laboratory evolution (ALE) under high isobutanol concentrations. Subsequently, 16 putative genes responsible for isobutanol tolerance were identified by transcriptomic analysis. When overexpressed in E. coli, four genes (fadB, dppC, acs, and csiD) conferred isobutanol tolerance. A fermentation study with a reverse engineered isobutanol-producing E. coli JK209 strain showed that fadB or dppC overexpression improved isobutanol titers by 1.5 times, compared to the control strain. Through coupling adaptive evolution with transcriptomic analysis, new genetic targets utilizable were identified as the basis for the development of an isobutanol-tolerant strain. Thus, these new findings will be helpful not only for a fundamental understanding of microbial isobutanol tolerance but also for facilitating industrially feasible isobutanol production.

    Abstract A randomized, double-blind, placebo-controlled trial was designed to assess the efficacy of the parabiotic Bifidobacterium breve IDCC 4401, named BBR 4401, for lowering cholesterol levels. The 66 subjects (per protocol set, n = 60) with low-density lipoprotein-cholesterol (LDL-C) levels between 100 mg/dL and 150 mg/dL were enrolled after a 4-week run-in period (e.g., no probiotics, low cholesterol diet and no food affecting lipid profiles). The two groups were prescribed 1 × 10¹⁰ (low-dose) and 1 × 10¹¹ CFU (high-dose), whereas the placebo group was prescribed 97% (w/w) of maltodextrin for 4 weeks. The compliance rates exceeded 97% in the subjects who completed the study. Comparison of the mean changes from baseline between the placebo group and test groups after the 12 weeks of BBR 4401 consumption showed a statistically significant reduction in LDL-C (up to −10.8%, p-value = 0.008) and apolipoproteinB (up to −8.1%, p-value = 0.008). Meanwhile, there were no clinically significant changes in vital signs, clinical pathology tests or electrocardiograms and no significant adverse events were reported during the study period. Concerning bowel habits, the consumption of BBR 4401 alleviated defecation strain, distension and watery feces in the high-dose group. Thus, BBR 4401 may be a safe and functional food for adults with moderate hypercholesterolemia.
