    Lab book june 6

    Names: Jon and Kieran

    We stained inoculated biofilms and performed the Crystal Violet assay. Left in 37 C for 36 hours. We did 4 trials 100uL, 4 trials 200uL, and 4 trials 300uL. Biofilm formation was successful, with varying band thickness. We also replicated this with two 5mL LB petri dish inoculated with 20uL E.coli. We added 5mL of crystal violet each to the petri dishes to cover the whole plate.

    We also performed an oxalic acid gradient with 0%, 0.05%, 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, and 2.0% oxalic acid to give a final volume of 6mL. We added 20uL of E.coli to each 6mL tube. Left in 37 C.

    We did a 1/100 dilution of E.coli into LB media, and left it in 37 C for (hopefully) 24 hours. We did 4 trials 100uL, 4 trials 200uL, and 4 trials 300uL.

    Biofilm produced on 24h 96 well plate.

    Testing to see if biofilm will produce on 12h 96 well plate (1 in 100 culture dilution).

    And also doing 24h 96 well biofilm formation testing to see what detergents and chemical impacts have on the decrease in biofilm production.

    *Biofilms placed at 8:00pm

    Oxalic acid test run for 12 hours (0, 0.01, 0.05, 0.1, 0.15, 0.2, 0.4, 0.4, 0.5, 2.0%)

    *Oxalic acid placed at 7:30pm

    Tested the production of parafilm sacs for in vitro Varroa feeding. (using kimwipes and 2mL tubes as containment methods) .

    Names: Kieran

    Performed oxalic acid testing of E.coli growth in LB media at (0, 0.01, 0.05, 0.1, 0.15, 0.2, 0.4, 0.4, 0.5, 2.0%) concentrations. Placed at 6:50pm.

    Produced more biofilms.

    Had mites and created pouches including Water, LB, Supernatent, E.coli, E.coli RFP. Placed at room temperature and in chris’s drawer.

    Took 48 and 24 hour biofilms and performed a bleach treatment on them (0.252%) for 30 minutes. .

    Names: Kieran

    Took oxalic acid readings after 23 hours of incubation

    .

    Title for table
    Oxalic Acid Concentration (%) OD600
    0.0 1.745
    0.01 1.771
    0.05 1.882
    0.1 0.980
    0.15 0.125
    0.2 0.104
    0.3 0.118
    0.4 0.174
    0.5 0.1456
    2.0 0.017

    Readings are unrealiable as the cultures were left in the shaking incubator for over 23 hours. Still show the same general trend as past gradients.

    Objective:Determine if we have successfully cultured mites in vitro using either paraffin pouches or bee pupae.

    Table 2. Experimental design showing each of the treatments applied to the mites.

    After 24 hours, all mites were found to be dead. Pupae showed some signs of black bacteria growth or browning on body. Will need to repeat or find another method of culturing mites in vitro.

    Names: Chris and Ross

    Objective:Determine if the concentration of oxalic acid that kills bacteria will kill bees.

    Procedure:Bees were obtained from the “Mighty Hive” near the penitentiary at 4:00 and placed into 5ml centrifuge tubes. The bees were transported to the University of Lethbridge and stored at room temperature until 8:00. Prior to experimentation, the tubes were supplemented with a sugar water solution to ensure that the bees would not starve. Following feeding, 2ml of each treatment were added to the 5ml tubes containing the bees and set horizontally along the bench. The abdomen of each bee was immersed in the treatment no matter what orientation the bee took. The bees were observed for 1 hour and subsequently euthanized in 70% EtOH.

    Treatment Before After
    none Somewhat lethargic. Drank when prompted. Appeared tired but otherwise unaffected.
    0.00% Most lethargic, did not eat when offered. Wet, and slow moving.
    0.05% Very vigorous; ran around inside the tube. Fed. Very energetic. Unaffected by treatment.
    0.20% Very vigorous; ran around inside the tube. Fed. Slightly less energetic than the 0.05% bee.

    Table 1. Observations of the bees following 60 minutes of exposure.

    Discussion:The bees showed that they could survive well in concentrations of oxalic acid that were above the point where E.coli would die. Further tests must be done to determine the exact contact toxicity. Additionally, the contact toxicity to mites will need to be addressed.

    Conclusion:The bees will be able to survive all of the oxalic acid that the E.coli can produce.

    Bee: A More Specific Oxalic Acid Gradient

    Objective: Determine a more specific concentration of oxalic acid that will prevent cell growth. Already we know that oxalic acid prevents cell growth between 0.05% and 0.2%. Now we want to determine a more specific concentration of oxalic acid that will prevent cell growth.

    Oxalic Acid Concentration (%) OD600
    0.05
    0.07
    0.1
    0.125
    0.13
    0.17
