- Aquarium room. The Kenkel lab includes one saltwater aquarium room (369 ft2) for rearing coral and conducting controlled temperature and pCO2 experiments. The room will house two recirculating temperature-controlled saltwater aquarium systems. Both systems are equipped with auto-DI top-off systems, protein skimmers, and biological and mechanical filtration systems. The first is the husbandry system, which is comprised of two 500-L holding troughs equipped with 12 AI Hydra 52 lights. Water from these troughs circulates with three 50-L breeding tanks designed to hold adult colonies during spawning and trap released larvae. The second system is the experimental system, which is comprised of 16 50-L tanks. Each tank is equipped with its own heater, CO2 solenoid, pH controller, biological and mechanical filtration and AI Prime HD light. Tanks have been designed to have flexible water exchange, such that they can be completely recirculating (UV-sterilized) or completely independent experimental units, facilitating flexible experimental design treatments, such as addition of chemicals or putative pathogens.Shared equipment (upon request):
- Biotek H1M spec plate reader
- Omni bead beater
- Metrohm automatic titrator
- Agilent AriaMx qPCR
Laboratory. Dr. Thrash’s laboratory (1500 sq. feet) is located in the Allan Hancock Foundation building at the University of Southern California. The lab is equipped for large-scale water collection and transport with 1-20 L polycarbonate carboys, filtration equipment (Cole-Parmer Masterflex I/P peristaltic pump; 142 mm, 55 mm, 47 mm, and 25 mm filter assemblies; Millipore Pellicon tangential flow filtration assembly; tubing), a -20˚C and -80˚C freezer, a refrigerator, 6 dry incubators, portable cold incubators, complete molecular biology facilities for nucleic acid extraction and PCR (bead-beater, vortexes, dry baths, water baths, thermal cyclers and BioRad GelDoc EZ Imager, gel trays and power supplies, Life Technologies Qubit Fluorometer, Eppendorf refrigerated and unrefrigerated microcentrifuges and benchtop hanging bucket centrifuge), 24” AirClean portable laminar flow workstation, portable cold incubators, a PreSens optode system, vacuum pump, fume hood, Millipore Milli-Q water purification system, a full suite of chemical stocks, balances, and a pH meter.
Cultivation Infrastructure. The Thrash Lab has a dedicated cultivation room containing a Millipore Guava EasyCyte 5HT HPL benchtop flow cytometer for cell counting using a 488nm laser (which is capable of being transported and deployed shipboard), a BD Accuri C6 Plus flow cytometer with 488nm and 640 nm lasers and an autosampler, a class II/A biosafety cabinet for containment-free media inoculation and culture manipulation, an Eppendorf epMotion 5075 fluid-handling robot with HEPA-filtered chamber, and a BD Influx fluorescence activated cell sorter with 355nm, 488nm, and 640nm lasers. Elsewhere in the lab are two ThermoScientific Locator 6 Plus liquid nitrogen dewars for culture collection storage, and a dedicated bench and tank storage system for anaerobic cultivation. We also have a COY Class A anaerobic chamber and a microaerophilic glove box. We have a full suite of cultivation vessels, including serum bottles, 50 custom 96 x 2.1 mL PTFE plates, and polycarbonate and PTFE flasks of varying sizes. Finally, the lab has an acid bath for trace-metal clean cultivation.
