Mass culture, apparently concerned with commerce, technique and the mass culture is actually a modern sensation of the daily life.

Carbon and nitrogen metabolic characteristics in biological aeration filter;

By use of 12 L glass fermentor, the metabolic characteristics of the mutant strain of GM screned by the laboratory, whose capability of prodacing GM is better than starting strain, have been studied.

The metabolic properties and functional diversity of the microbial community in horizontal sub-surface flow constructed wetlands were analyzed through the sole-carbon-source utilization profiles using ECO Biolog microplates.
