Demonstrations of microbe-mediated mineral formation in biofilms implicate this mode of microbial life in geological evolution and remediation of inorganic contaminants.
Activation of cellular mechanisms involved in stress response-signaling and -regulation upon exposure to stress conditions as well as activation of systems involved in oxidative stress defense and maintenance of protein quality might be an essential and general mode of microbial stress adaptation and enhancement of bacterial robustness.
The analysis of prokaryotic genome dynamics described here unequivocally shows that rapid gene flux involving extensive loss of genes and families, partially balanced by gain of new gene families via HGT, is the principal mode of microbial evolution.
Jin et al. (2015) investigated the effect of different aeration modes on microbial communities of a Carrousel oxidation ditch by high-throughput 454 Pyrosequencing, of which activated sludge samples were sampled from anoxic and oxic zones and mixed with same proportion.
The objective of this work is to compare the effects of thymol via three delivery modes (instant addition, time release, and combined mode) on microbial inhibition of Escherichia coli DH5α.
Using the orthogonal design method, the concentration of activating nutrient, air injection quantity, injection PV and injection mode of indigenous microbial flooding were optimized.
Second, many bird species regurgitate food to their young, thus permitting a mode of vertical microbial transmission that most mammals lack.
Metsulfuron-methyl is considered to have high soil activity and a soil half-life that varies between 5 and 63 days (Ismail and Lee 1995; Günther et al. 1989; Trabue et al. 2006), with the principal modes of degradation being microbial breakdown and chemical hydrolysis (Beyer et al. 1987).
The current modes of generating PLA involve microbial fermentation of starting material, lactic acid (LA), followed by chemical ring-opening polymerization.
