Picture shows both grew on LB Strep, are you sure your wild type is not resistant? The Wild Type looks far more resistant...or cell density at streaking point was higher. If you have access you may want to PCR to confirm. Also use a high fidelity polymerase since you are looking for a single nucleotide change. Either way glad you conducted the experiment. I would suggest doing a repeat or two just to be sure :)

Hi guys,--i think i have successfully CRISPRed an E. Coli bacteria,I have used the kit sold here:I followed the protocol here:The gene that was targeted is Escherichia coli 30S ribosomal subunit protein S12 (rpsL) gene. One base pair was changed to render the bacteria resistant to streptomycin.The picture attached shows my result. That plate contains a gel with streptomycin. The top part shows growth on the CRISPRed strain, the bottom part shows not growth on the normal strain.What you guys think ?I'm thinking of having the DNA of that gene sequenced, just to check if the edit really happened only where expected.
