Bioremediation of chlorinated aliphatic hydrocarbon-contaminated aquifers can be hindered by high contaminant concentrations and acids generated during remediation. Encapsulating microbes in hydrogels may provide a protective, tunable environment from inhibiting compounds; however, current approaches to formulate successful encapsulated systems rely on trial and error rather than engineering approaches because fundamental information on mass-transfer coefficients is lacking. To address this knowledge gap, hydronium ion mass-transfer rates through two commonly used hydrogel materials, poly(vinyl alcohol) and alginic acid, under two solidification methods (chemical and cryogenic) were measured. Variations in hydrogel crosslinking conditions, polymer composition, and solvent ionic strength were investigated to understand how each influenced hydronium ion diffusivity. A three-way ANOVA indicated that the ionic strength, membrane type, and crosslinking method significantly (p < 0.001) contributed to changes in hydronium ion mass transfer. Hydronium ion diffusion increased with ionic strength, counter to what is observed in aqueous-only (no polymer) solutions. Co-occurring mechanisms correlated to increased hydronium ion diffusion with ionic strength included an increased water fraction within hydrogel matrices and hydrogel contraction. Measured diffusion rates determined in this study provide first principal design information to further optimize encapsulating hydrogels for bioremediation.

Enteric disease is the predominant cause of morbidity and mortality in young -mammals including pigs. Viral species involved in porcine enteric disease -complex (PEDC) include rotaviruses, coronaviruses, picornaviruses, astroviruses -and pestiviruses among others. The virome of three groups of swine samples -submitted to the Kansas State University Veterinary Diagnostic Laboratory for -routine testing were assessed, namely, a Rotavirus A positive (RVA) group, a -Rotavirus co-infection (RV) group and a Rotavirus Negative (RV Neg) group. All -groups were designated by qRT-PCR results testing for Porcine Rotavirus A, B, C -and H such that samples positive for RVA only went in the RVA group, samples -positive for >1 rotavirus went in the RV group and samples negative for all were -grouped in the RVNeg group. All of the animals had clinical enteric disease -resulting in scours and swollen joints/lameness, enlarged heart and/or a cough. -All samples were metagenomic sequenced and analyzed for viral species -composition that identified 14 viral species and eight bacterial viruses/phages. -Sapovirus and Escherichia coli phages were found at a high prevalence in RVA and -RV samples but were found at low or no prevalence in the RV Neg samples. -Picobirnavirus was identified at a high proportion and prevalence in RV Neg and -RV samples but at a low prevalence in the RVA group. A sequence analysis of the -possible host of Picobirnaviruses revealed fungi as the most likely host. -Non-rotaviral diversity was highest in RVA samples followed by RV then RV Neg -samples. Various sequences were extracted from the sample reads and a -phylogenetic update was provided showing a high prevalence of G9 and P[23] RVA -genotypes. These data are important for pathogen surveillance and control -measures
Polyoxometalate clusters embedded into hydrogel biobeads may be able to solve -the challenges posed by free proton generation during remediation of -trichloroethylene by acting as buffers and reducing protons to hydrogen gas. In -this thesis, the challenges posed by systems that contain both diffusion and -reaction processes for protons are considered mathematically, and a computer -simulation to was developed to prove the relationship between diaphragm cell lag -period and reactive capabilities of membranes. Two polyoxometalate compounds, -sodium decavanadate and alumina sulfate, were successfully incorporated into a -poly(vinyl alcohol) hydrogel membrane, and the diffusivity changes associated -with each compound was determined. It was found that the diffusivity of protons -through an unmodified 10% w/v poly(vinyl alcohol) membrane was 1.76 × -10-5 -cm2 -s-1 -, the diffusivity through a -10%/2% w/w/v poly(vinyl alcohol)/sodium decavanadate membrane was 3.10 × -10-6 -cm2 -s-1 -, and the diffusivity through a -10%/2% w/w/v poly(vinyl alcohol)/alumina sulfate membrane was 3.32 × -10-7 -cm2 -s-1 -. Through analysis of the -diaphragm cell lag period, it was found the incorporation of sodium decavanadate -did not increase the reactivity of a poly(vinyl alcohol) hydrogel, and -incorporation of alumina sulfate lowered the reactivity. These results indicate -that polyoxometalate integration into hydrogel membranes is feasible, but does -not provide any advantage to a bioremediation scenario.
Early colonization of the rumen microbiome is critical to host health and long -term performance. Factors that influence early colonization include maternal -factors such as gestational nutrition and mode of delivery. Therefore, we -hypothesized that late gestational nutrition and mode of delivery would -influence the calf rumen microbiome. Our objectives were to determine if -nutrient restriction during late gestation alters the calf rumen microbiome and -determine if ruminal microbiome composition differs in calves born vaginally -versus caesarean. Late gestating Angus cows were randomly allocated to one of -three treatment groups: control (CON; n = 6), caesarean section (CS; n = -4), and nutrient restricted (NR; n = 5), where CON were fed DDGS and hay to -meet NRC requirements and calved naturally; CS were fed similarly to CON and -calves were born via caesarean section; and NR were fed at a level to reduce BCS -by 1.5-2.0 points over the last trimester compared to CON and calved naturally. -Rumen fluid was collected via oral lavage prior to partition from cows and at d -7 from calves. Microbial DNA was isolated from the rumen fluid and metagenomic -shotgun sequencing was performed using the Illumina HiSeq 2500 platform. -Sequence data were analyzed using Metaxa2 for taxonomic assignment followed by -QIIME1 and QIIME2 to determine differential abundance and alpha- and -beta-diversity differences. There were no significant differences in -alpha-diversity as measured by shannon index across treatment groups for cows -(P = 0.239), but there were significant differences for calves (P = 0.015). -Similarly, there were no significant differences in beta-diversity as measured -by the bray-curtis dissimilarity matrix for cows (P = 0.059), but there were -significant differences for calves (P = 0.007). Alpha-diversity differed (P -< 0.001) between cows and calves, with cows having increased species richness -compared to calves. Beta-diversity also differed (P = 0.001) between cows and -calves. At total of 410 taxa were differentially abundant (P < 0.01) between -cows and calves. These results suggest that the mature rumen microbiome of cows -is able to withstand changes in feed intake, however the calf microbiome is -susceptible to alteration by maternal factors. These data also suggest that -there may be opportunities to develop management strategies during late -gestation that influence calf health and performance long-term.

Polyvinylalginate (PVA) shows promise as a useful shield for microorganisms carrying out bioremediation of TCE by surrounding them in a protective biofilm-like layer, however, key information is missing which relates diffusion of TCE or its metabolic products through PVA. +Read more »
Enteric disease is the predominant cause of morbidity and mortality in young mammals including pigs. Viral species involved in porcine enteric disease complex (PEDC) include rotaviruses, coronaviruses, picornaviruses, astroviruses and pestiviruses among others. The virome of three groups of swine samples submitted to the Kansas State University Veterinary Diagnostic Laboratory for routine testing were assessed, namely, a Rotavirus A positive (RVA) group, a Rotavirus co-infection (RV) group and a Rotavirus Negative (RV Neg) group. +Read more »

Trichloroethylene (TCE), a toxic and carcinogenic contaminant, presents unique challenges for cleanup because of its water solubility, density, and volatility. Bioremediation of TCE is a promising cleanup method; however, metabolism of TCE results in acid generation that inhibits remediating microorganisms. Calcium alginate(CA)-polyvinylalcohol (PVA) hydrogels show promise for protecting remediating microbes, however diffusion of TCE or its byproducts through these polymers is unknown. To measure the effective diffusion coefficient of TCE and byproducts through hydrogel membranes, we used a modified diaphragm cell. +Read more »

Bioremediation of chlorinated aliphatic hydrocarbon-contaminated aquifers can be hindered by high contaminant concentrations and acids generated during remediation. Encapsulating microbes in hydrogels may provide a protective, tunable environment from inhibiting compounds; however, current approaches to formulate successful encapsulated systems rely on trial and error rather than engineering approaches because fundamental information on mass-transfer coefficients is lacking. To address this knowledge gap, hydronium ion mass-transfer rates through two commonly used hydrogel materials, poly(vinyl alcohol) and alginic acid, under two solidification methods (chemical and cryogenic) were measured. +Read more »
Early colonization of the rumen microbiome is critical to host health and long term performance. Factors that influence early colonization include maternal factors such as gestational nutrition and mode of delivery. Therefore, we hypothesized that late gestational nutrition and mode of delivery would influence the calf rumen microbiome. Our objectives were to determine if nutrient restriction during late gestation alters the calf rumen microbiome and determine if ruminal microbiome composition differs in calves born vaginally versus caesarean. +Read more »

Metagenomic classification tackles the problem of characterising the taxonomic source of all DNA sequencing reads in a sample. A common approach to address the differences and biases between the many different taxonomic classification tools is to run metagenomic data through multiple classification tools and databases. This, however, is a very time-consuming task when performed manually - particularly when combined with the appropriate preprocessing of sequencing reads before the classification. Here we present nf-core/taxprofiler, a highly parallelised read-processing and taxonomic classification pipeline. +Read more »

I always get the comment that our implements are old whenever I show this video off. I just ignore the naysayers, though, and good thing, too, because a version of this video won a GoPro Award. Still -waiting to see my footage on their channel, though.
The culmination of all art forms is that of film.
A good film must have the plot and language of a good novel, characters as bold and stunning as sculpture, a rhythm as driving and delicate as poetry, frame compositions more stellar that those of photography, and music that speaks to -the souls of both the characters on screen and the viewers off.
But I digress. Most of my forays into the world of film are immortalized on my -Vimeo account, but I decided to share a few -highlights here. Enjoy!
