The invention discloses a method for ecologically restoring polluted water by applying a compound microorganism technology. A compound microorganism thallus concentrated solution consists of the following 10 thalluses in parts by weight: 5 to 15 parts serratia, 5 to 15 parts of photosynthetic bacteria, 5 to 15 parts of yeast cell, 5 to 15 parts of denitrifying bacteria, 5 to 15 parts of lactic acid bacteria, 5 to 15 parts of actinomycetes, 5 to 15 parts of BD bacteria, 5 to 15 parts of nitrogen-fixing bacteria, 5 to 15 parts of nitrifying bacteria and 5 to 15 parts of bacillus subtilis, wherein the total bacterial count in the compound microorganism thallus concentrated solution is not less than 109 pic / ml. According to the invention, the treating process is environment-friendly, healthful and safe, undesirable odor such as hydrogen sulfide and ammonia nitrogen is not easy to generate, the transparency of the restored water is more than 1.5 m, and the removal ratio on algae, total nitrogen, total phosphorus and COD is 95-99%, 95-99% , 90-95% and 90-95% respectively.

The invention provides methods of producing secondary metabolites and under recombinant products oxygen-limited or anaerobic culture conditions. The methods include providing a porous substrate having a first side and a second side and which has a biofilm of microorganisms attached to the first side thereof, and causing a nutrient solution to flow through the biofilm and the substrate in a direction from the first side thereof to the second side thereof under oxygen-limited or anaerobic culture conditions. The microorganisms include Clostridium sp., Bacillus sp., Pseudomonas sp. Vibrio sp., Serratia sp., Rhodopseudomonas sp., Anaeromyxobacter sp., Desulphovibrio sp., and Candida sp., Lactococcus lactis, Escherichia coli, Bacillus subtillus, Pichia sp., Candida sp., Hansenula polymorpha and Saccharomyces cerevisiae.
