Our initial expectations of the microbial diversity living within and on human beings were limited and biased because relatively few microbes can be grown in culture (Rappé and Giovannoni 2003; Staley and Konopka 1985) and because many phylogenetically and functionally distinct kinds of microbes are difficult to distinguish by morphological or biochemical characteristics.
However, the demise of these microbes can be enhanced by factors such as taking antibiotics.
According to David Fronk, vice president of clinical research, all surgery is risky and microbes can be introduced through many routes, including operating rooms and surgeons.
But if the fruit is peeled and then washed with contaminated water, microbes can be ingested, and that is how most tourists get sick, he said.
Marine biologists are also sampling seawater in the same way, to see what kind of bacteria and other microbes can be found there.
The scientists said later that the experiments were peaceful; the two microbes can be found side-by-side in nature and, the Russians said, they wanted to see what happened if they cross-bred.
Microbes can be engineered to produce complex structures from simple, inexpensive precursors under standardized control.
In addition, genetically modified microbes can be designed as local delivery of therapeutic molecules.
Microbes can be readily cultured and their genomes can be easily manipulated.
Microbes can be engineered to consume various carbon sources, and accumulate increased amounts of fatty acids with different composition.
Biological systems, either employing plants or microbes, can be a manufacturing route once pathways are delineated, standardized, and scaled up.
