Bacteria have developed sophisticated modes of cooperative behavior to cope with unfavorable environmental conditions. Here we report the effect of antibiotic stress on the colonial development of Paenibacillus dendritiformis and P. vortex. We focus on the effect of co-trimoxazole on the...

We present the morphology diagram (morphologies as function of peptone levels and agar concentrations) observed during colonial development of Paenibacillus alvei bacteria. These bacteria are close to Paenibacillus dendritiformis and have been studied extensively in the past. Like P....
