microbes has increased remarkably due to technical developments in nucleotide
sequencing of environmental DNA, most of the constituents of microbial
populations have not yet been cultivated hence we still do not know the true diversity
of microorganisms. Probably, the occurrence of complex and invisible interactions
significantly correlates with the unculturability of these microorganisms. The wide
variety in terms of their functional, physiological, and taxonomic properties is also
an important aspect of rigid community structure.
Finally, the initial part of “Ho-job-ki, “the famous literature written by the
Japanese essayist Kamo-no-Chomei on 1212, is cited to end the chapter.
The flowing river never stops
ゆく河の流れは絶えずして、
and yet the water never stays the same.
しかも、もとの水にあらず。
Foam floats upon the pools,
淀みに浮かぶうたかたは
scattering, re-forming,
かつ消えかつ結びて、
never lingering long.
久しくとどまりたるためしなし。
So it is with man
世の中にある人と
and all his dwelling places
栖とまたかくのごとし。
here on earth.
