This study aimed to clarify whether the transcript levels of the transgenes and those of plant stress response markers (i.e., hypersensitive response and endoplasmic reticulum [ER] stress) could be primary determinants of the accumulation of recombinant influenza hemagglutinin (HA) at 21 or 26°C. We found no correlation between the transgene expression levels (HA, RdRP, and MP) and the number of days needed to reach the maximum HA protein content at both temperatures. Regardless of the accumulation compartment, HA protein content peaked earlier at 26°C than at 21°C. The rapid reduction of HA content after reaching the maximum, observed only in the ER at 26°C, correlated with severe necrosis and high transcript levels of two representative ER stress markers, bZIP60 and BiP. This correlation suggests that high postinfiltration air temperature affects HA accumulation primarily through ER stress, a key factor in the rapid reduction of HA content after the peak.","PeriodicalId":9168,"journal":{"name":"Biotechnology and Bioengineering","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143063719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the optimization of the CHO cell culture process is very complex and influenced by various factors. This study investigates the use of machine learning (ML) algorithms to optimize an established industrial CHO cell cultivation process. A ML algorithm in the form of an artificial neural network (ANN) was used and trained on datasets from historical and newly generated CHO cell cultivation runs. The algorithm was then used to find better cultivation conditions and improve cell productivity. The selected artificial intelligence (AI) tool was able to suggest optimized cultivation settings and new condition combinations, which promised both increased cell growth and increased mAb titers. After performing the validation experiments, it was shown that the ML algorithm was able to successfully optimize the cultivation process and significantly improve the antibody production. The best results showed an increase in final mAb titer up to 48%, demonstrating that the use of ML algorithms is a promising approach to optimize the productivity of bioprocesses like CHO cell cultivation processes clearly.","PeriodicalId":9168,"journal":{"name":"Biotechnology and Bioengineering","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143063720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The integrated models correctly represented all experimental observations and identified mechanisms underlying how and why AnMBBR performance changed when the volumetric loading rate (VLR) of total chemical oxygen demand (TCOD) increased from 3.9 to 19.5 kg CODT/m3-d. The fractional removal of TCOD and CH4 production decreased as the VLR of TCOD increased, in part, due to an increasing biofilm thickness that filled the protected channels in the interior of the plastic carriers and led to a decrease in biofilm surface area and an increase in the mass-transfer boundary layer. Also, the ~25-day duration for each VLR of TCOD was too brief to allow the biofilm to establish a new quasi-steady state with respect to biofilm thickness. The mechanistic understanding of how biofilm characteristics and process performance respond to increased VLR of TCOD can be applied in engineering practice to improve AnMBBR process design and operation.","PeriodicalId":9168,"journal":{"name":"Biotechnology and Bioengineering","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143063721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Screening of small-scale cultures (75 mL) at 75°C revealed that ~pH 3.0 was a maximal threshold for bioleaching onset. Subsequently, chalcopyrite at 10 g/L in 750 mL culture media, containing small amounts of ferric ion, adjusted to pH 2.5 with sulfuric acid and incubated for 24 h at 75°C before inoculation, brought the pH to approximately 3.0 through abiotic chemical reactions. However, the resulting subtle differences in pHinitial (3.0 ± 0.15) in bioleaching cultures, while not affecting microbial growth, were critical to bioleaching onset and progress. Initial iron levels were less important than pHinitial in starting the bioleaching process. X-Ray Diffraction (XRD) surface analysis informed bioleaching trajectories over 21 days and reinforced the impact of pHinitial. The subtle differences in pHinitial markedly affected S. ohwakuensis onset and outcomes, as it presumably would for other bioleaching thermoacidophilic archaea.

The tolerant mutant SEC4.0 was characterized through comprehensive analysis of whole genome sequence, transcriptome, and phosphoproteome. The findings revealed that the high resistance of SEC4.0 was not primarily due to large-scale transcriptional upregulation of stress response genes, but rather through alterations in the phosphorylation levels of lipid-related pathways. PKC1 mutations that affect stress signal transduction and SPT3 mutations that affect arginine biosynthesis have been shown to significantly enhance 2-PE resistance. This study also investigated the effects of exogenous amino acid addition and synergistic effects with two key mutanted genes on 2-PE resistance.

However, large-scale implementation is hindered by our inability to predict performance as a function of key operational parameters. A predictive mathematical model would be a valuable tool for designing efficient FA-based systems. Developing accurate models is challenging due to dynamic environmental conditions and the spatial complexities of FA cultures. In this work, a model was developed to mathematically describe the biomass productivity of static FA cultures (mats and turfs) in relation to the incident light intensity and temperature. The model was validated against published data to investigate the influence of time-dependent inhibition (inhibition from sustained light exposure) on productivity. When time-dependent inhibition was included in the model, predictions were within ~10% of experimental values, however, without including time-dependent inhibition there was a sixfold overestimation of biomass productivity. The model could also generate predictions of the effects of time-dependent inhibition during diurnal light fluctuations using experimentally determined rate constants. The model represents a powerful tool for optimizing the design and operational parameters in FA cultures that could be further expanded to incorporate the influence of nutrient and CO2 availability.","PeriodicalId":9168,"journal":{"name":"Biotechnology and Bioengineering","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143063717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although photolithography technology has been extensively employed to fabricate a variety of anisotropic patterned structures to guide cell growth, it remains a great challenge to design high-resolution micro/nano hierarchical structures directly onto medical titanium (Ti)-based implants. Herein, we present a rapid, reliable and reproducible approach combining photolithography and hydrothermal technology to construct a micro/nano hierarchical structure including anisotropic micro-strips and a porous structure composed of TiO2 nanotubes features. In vitro biological and physicochemical analyses revealed that the micro/nano hierarchical structures not only efficiently facilitate the localization and adsorption of BSA molecules, but also enhances the control of cell growth behavior. The synergistic effect between the physical limitation for organizing cellular cytoskeleton at micropattern and the control of focal adhesion sits at the nanoscale can effectively guide cells to maintain stable elongation and alignment, even at large micro-stripe width of 100 μm. This study presents a promising strategy to precisely construct micro/nano multi-level patterned structure on Ti substrate using biomaterials with excellent biocompatibility. These functional micro/nano hybrid micropatterns offer a powerful platform for regulating bioreagent localization and cell behaviors in various applications including tissue engineering, regenerative medicine, drug screening, and biosensors.","PeriodicalId":9168,"journal":{"name":"Biotechnology and Bioengineering","volume":"48 1","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143057115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
