 \n\nOptimization of water extraction conditions for removal of yeast inhibi
 tory compounds from switchgrass\n\nAuthors: Iman Najafipour\, Dr. Rebecca O
 ng\n\nAbstract: Drought-stressed switchgrass\, a potential bioenergy feedst
 ock\, often exhibits elevated yeast inhibitor. Effective removal of inhibit
 ory compounds enhances sugar conversion to bioethanol\, maximizing energy p
 roduction\, yield\, and cost-efficiency. The objective is to optimize Accel
 erated Solvent Extraction (ASE) for efficient yeast inhibitor extraction\, 
 thereby increasing yield while minimizing water consumption. The impact of 
 temperature (A)\, time (B)\, and extraction cycles (C) on the extracted mas
 s was investigated using a Box-Behnken model. A\, B\, C\, AB\, BC\, and CC 
 terms influenced the extraction\, aligning well with experimental data. Thi
 s ongoing project examines how extraction conditions affect yeast inhibitio
 n\, and fermentation.\n\nPoster #2\n\nMicrobial Community Forms Biofilm in 
 Hybrid Chemical-Biological Upcycling Process\n\nAuthors: Hunter Stoddard\, 
 Dr. Rebecca Ong\n\nAbstract: Biofilms can form on process equipment and mak
 e harvest of the cell biomass challenging. In this study\, a microbial cons
 ortium was grown on products from pyrolysis and from depolymerization using
  ammonium hydroxide. Bioreactor conditions were varied to determine the hig
 hest production of biomass and the proportion of biomass as a biofilm. It w
 as determined that the most biomass was produced at 30°C\, pH 7\, 100 rpm a
 gitation\, and 10 sL/h airflow. Reducing temperature and increasing aeratio
 n had the largest impact on biofilm formation where the percentage of bioma
 ss that was attached as biofilm was 20.8% at 30°C and 27.8% at 10 sL/h airf
 low.\n\nPoster #3\n\nPrediction of ex-situ Direct Carbonation of Natural Mi
 nerals using Machine Learning Algorithms\n\nAuthors: William Hanson\, Dr. L
 ei Pan\n\nAbstract: Mineral carbonation is a carbon fixation method in whic
 h the atmospheric CO2 reacts with alkaline oxide/silicate minerals to form 
 carbonate minerals. In this work\, mineral carbonation efficiency for the d
 irect carbonation of various natural silicate minerals was investigated. In
  addition\, carbonation efficiency was modeled using machine learning techn
 iques including gradient boost\, random forest\, artificial neural network\
 , K-nearest neighbor\, and self-building neural network. Among models teste
 d\, gradient boost had the lowest error while artificial neural networks ha
 d the highest error. The present result is to ensure that industrial-scale 
 carbonation operations will be optimally designed.\n\nPoster #4\n\nInvestig
 ating thermal stabilization of porcine parvovirus by sugars and amino acids
 \n\nAuthors: Idris Tohidian\, Lynn Manchester\, Rohan Chaudhari\, Dr. Caryn
  Heldt\n\nAbstract: Developing thermostable vaccines not only reduces vacci
 nation cost\, but also increases their widespread distribution all over the
  world. To achieve this goal\, we focused on unravelling the stabilization 
 ability of four sugars and five amino acids frequently used as additives in
  biotherapeutic formulations today. Both dry and liquid formulations were e
 xplored. The results showed good stabilization effect of sugars in liquid a
 nd dry formulations\, but the amino acids were able to stabilize porcine pa
 rvovirus only in the dry state.\n\nPoster #5\n\nAquous two phased system fo
 r influenza b virus purification\n\nAuthors: Tara Sarvari\, Liza Korolkov\,
  Amanda Bekkala\, Lynn Manchester\, Dr. Caryn Heldt\n\nAbstract: We live in
  a time where viruses are constantly developing\, and millions of people co
 uld be infected before we can respond. The influenza A and B viruses are tw
 o examples of viruses that can cause serious respiratory infections in huma
 ns. To reduce the time required to produce a pure vaccine\, we need to have
  fast\, efficient\, and robust purification techniques. Current vaccine pur
 ification methods are time-consuming and labor-intensive\, as well as expen
 sive and low yield. Aqueous two-phase extraction (ATPE)\, which may be prog
 rammed to run continuously\, is an excellent alternative for the purificati
 on of influenza A and B viruses.\n\nPoster #6\n\nLow-cost\, Stable\, and Se
 lective Synthetic biosensors for Lactate Detection\n\nAuthors: Grace Dykstr
 a\, Dr. Yixin Liu\n\nAbstract: High lactate levels can be a sign of lactic 
 acidosis and is attributed to sepsis and septic shock\, cardiac arrest\, lu
 ng disease\, and trauma within the body. Electropolymerized Molecularly Imp
 rinted Polymers (eMIPs) can be used to develop biosensors with a molecularl
 y imprinted cavity as their recognition element\, with major advantages of 
 low-cost\, quick fabrication\, inherent selectivity\, and stability. We can
  further enhance eMIPs with Prussian blue (PB) nanoparticles deposited on t
 he electrode surface as a redox-active species to create label-free biosens
 ors for lactate detection with a one-step detection.\n\nUndergraduate Resea

 se Sample Throughput\n\nAuthors: Morgan Redding\, Mikayla Marshalek\, Andre
 a Senyk\, Dr. Rebecca Ong\n\nAbstract: One approach toward biofuel producti
 on requires lignocellulosic biomass to undergo high-solids enzymatic hydrol
 ysis to convert cell wall carbohydrates into fermentable sugars. However\, 
 our current process suffers from bottlenecks in sample throughput\, limitin
 g the types of experiments we can perform. To overcome bottlenecks in solid
 s separation\, enzymatic hydrolysis will be scaled down from 32 mL hydrolys
 ate volume to ~4–10 mL volume to allow for higher speed processing in micro
 centrifuge and avoid time consuming vacuum filtration. The new enzymatic hy
 drolysis procedure will be coupled with a revised pretreatment and micropla
 te fermentation to enable higher throughput processing and analysis of dive
 rse lignocellulosic feedstocks.\n\nPoster #8\n\nQuantifying Dielectrophoret
 ic Responses of RAW 264.7 Macrophages: Baseline and LPS Activated Cells\n\n
 Authors: Prajeet Kadam\, Juan Cruz-Moreno\, Holly Flores\, Nick Peterson\, 
 Roger Guillory\, Zainab Alshoug\, Dr. Adrienne R. Minerick\n\nAbstract: Mac
 rophages are critical effector immune cells that eliminate diseased or dama
 ged cells based on their nascent or activation state (induced via lipopolys
 accharide\, LPS). Dielectrophoretic (DEP) tools induce cellular charges tha
 t probe RAW 264.7 macrophages in baseline and LPS-stimulated states by obse
 rving changes in cell morphology and quantifying DEP spectra. This provides
  insights into cell membrane capacitance\, conductivity\, and polarizabilit
 y. A custom-designed microfluidic device precisely controls and monitors th
 e cell during DEP experiments\, revealing altered cell morphology\, stronge
 r DEP responses at higher voltages\, and distinctive responses in LPS-activ
 ated macrophages at lower frequencies.\n\nStudent Organization\n\nPoster #9

 a\, Dr. Jeana Collins\n\nAbstract: The American Institute of Chemical Engin
 eers (AIChE) develops the engineering students at MTU personally and profes
 sionally by offering them the opportunity to meet with industry representat
 ives. This connection allows our members to learn about what they do in the
 ir role with the company\, what their company does\, and grow an authentic 
 friendship. AIChE promotes the sharing of knowledge pertaining to the field
  of chemical engineering and sustainability. This organization has been inv
 olved actively in the community\, participating in Make a Difference Day an
 d more. AIChE is a Chem-E-Car sponsor\; this is a competition where student
 s design a chemical reaction-driven car and compete with other schools at b
 oth regional and national levels.
