The Effects Of Sample Storage Conditions On The Microbial Community Composition In Hydraulic Fracturing Produced Water, Daniel Lipus, Amit Vikram, Richard Hammack, Kyle Bibby, Djuna Gulliver

Roman L. Hruska U.S. Meat Animal Research Center: Reports

The petroleum industry has an increasing interest in understanding the microbial communities driving biofouling and biocorrosion in reservoirs, wells, and infrastructure. However, sampling of the relevant produced fluids from subsurface environments for microbiological analyses is often challenged by high liquid pressures, workplace regulations, operator liability concerns, and remote sampling locations. These challenges result in infrequent sampling opportunities and the need to store and preserve the collected samples for several days or weeks. Maintaining a representative microbial community structure from produced fluid samples throughout storage and handling is essential for accurate results of downstream microbial analyses. Currently, no sample handling or …

GE Healthcare specializes in providing optimized medium for companies culturing cells in bioreactors for pharmaceutical purposes. Small scale testing, typically in shaker flasks, is a crucial part of this process, but scaling between these and larger impeller driven reactors has proven difficult in the past.

This study sought to develop a relationship between shaker flask bioreactors and a micro-bioreactor setup called the ambr® system. Important scale-up parameters such as oxygen transfer rate, 𝑘_L𝑎, and energy dissipation rate, 𝜀_𝑎, were calculated and used to compare the two systems. The following equations were taken from literature [2],[3]:

Tertiary Ammonia Treatment Of Lagoon Effluent Using Microvi MneTm Technology, Bryan Burbank, Sydney Burtenshaw, Nathan Guymon, Mike Langston, Luke Lemmon

Biological Engineering

Nutrient pollution is a growing problem threatening many waterways. High levels of nitrogen and phosphorus in water can cause algae to grow rapidly. This growth decreases water quality, kills aquatic life, and elevates toxin levels creating health hazards for people. Due to increases in nitrogen and phosphorus pollution, the Logan City regional wastewater treatment plant is currently updating from a lagoon system to a mechanical plant to meet future discharge limits imposed by federal, state, and local governments. The intent of our design is to add a tertiary nitrification system using Microvi MicroNiche Engineering^TM (MNE^TM) technology.

Tertiary Wastewater Treatment Through Mbbr Technology, Ethan Ackerman, Grant Harris, Gregory Jensen, Christopher Ruben, Stephen Sadler

Biological Engineering

Wastewater treatment is an essential component to public health as it removes harmful compounds and allows for water reuse and recycle. Biological nutrient removal has entered into the public spotlight as effluent flows with high nitrogen concentrations have detrimental effects on water discharge bodies. Traditional suspended growth biological treatment methods are expensive and produce excess biomass that can reduce the efficiency of nutrient removal if not maintained. Research on the benefits of attached growth processes, namely moving bed biofilm reactor (MBBR) technology, presents an exciting innovation in wastewater treatment that can increase nutrient removal efficiency and reduce overall cost.

Pervasive Iron Limitation At Subsurface Chlorophyll Maxima Of The California Current, Shane L. Hogle, Christopher L. Dupont, Brian M. Hopkinson, Andrew L. King, Kristen N. Buck, Kelly L. Roe, Rhona K. Stuart, Andrew E. Allen, Elizabeth L. Mann, Zackary I. Johnson, Katherine A. Barbeau

Marine Science Faculty Publications

Subsurface chlorophyll maximum layers (SCMLs) are nearly ubiquitous in stratified water columns and exist at horizontal scales ranging from the submesoscale to the extent of oligotrophic gyres. These layers of heightened chlorophyll and/or phytoplankton concentrations are generally thought to be a consequence of a balance between light energy from above and a limiting nutrient flux from below, typically nitrate (NO₃). Here we present multiple lines of evidence demonstrating that iron (Fe) limits or with light colimits phytoplankton communities in SCMLs along a primary productivity gradient from coastal to oligotrophic offshore waters in the southern California Current ecosystem. SCML …
