In human gutmicrobiome, it is proposed that the most inner layer of bacterialcells (most close to the epithelial cells) is composed ofmicro-aerobes. These bacteria grow relatively faster and harvestenergy from diet better than strict anaerobes in the gut. Could youspeculate certain unique features of those micro-aerobes in energygeneration and cell metabolism?


It has been shown indifferent biofilm-forming bacteria that secreted small moleculesand proteins can trigger biofilm disassembly and cell dispersal inlate stages during biofilm development. Can you provide two suchexamples and discuss with molecular details how disassembly anddispersal occur? (Please read extra references ifnecessary)


Protein dynamics(accumulation and localization) plays a key role in Caulobactercrescentus development. Cell cycle control in C.crescentus is composed of four key regulatory proteins. Pleaseprovide two examples to explain why protein dynamics is criticalfor C. crescentus cell differentiation.
