1. Thus perhaps even clouds and rain may be biogenic.

2. The usual biogenic amine in beer is tyramine.

3. Fermentation is a biogenic process.

4. The power which makes organic matter transform into biogenic gas is the combined action of methanogenic bacteria and correlated microbial flora.

5. Biogenic amines are aliphatic, alicyclic or heterocyclic organic bases of low molecular mass, which arise as a consequence of metabolic processes in animal, plants and microorganisms.

6. The Quaternary biogenic gas reservoir in Qaidam Basin is provided with favorable conditions.

7. Biogenic amine is a kind of low molecular weight compounds containing nitric fatty group or heterocycle group . They have biological importance in vegetable, microbial and animal cells.

8. The appropriate biogenic amines are beneficial to normal physiology function of human body, but over absorption of which would have undesirable physiological effects on human beings.

9. Biogenic amine is a kind of iow molecular weight compounds containing nitric fatty group or heterocycle group. They have biological importance in vegetable, microbial and animal cells.

10. Consumption of food containing high amounts of biogenic amines may cause toxicological effects.

11. Biogenic amine is a kind of low molecular compounds belonging to nitric fatty group or heterocycle group.

12. Metal - biogenic type is a post magmatic mesothermal hydrothermal solution filling metasomatic ore deposit correlated with diabase.

13. Biogenic pesticides, also known as biological pesticides or biogenic natural product pesticides, develop from living resources.

14. The Permian coalbed methane(CBM) reservoir with mixed secondary biogenic and thermogenic gas in the Huainan Coalfield, Anhui Province, is affected by complex geological and hydrogeological factors.

15. Therefore , one cannot ignore the contribution of biogenic volatile organic compounds to the secondary organic aerosols.

16. Biogenic amine is also an important substance and has remarkable resistance of bacterial activity.

17. As for the pathway of biogenic amine the corresponding homologous solution was proposed in this paper.

18. The biogenic amines are harmful products of fermented foods, which affect their safety.

19. In food microbiology , biogenic amines sometimes have been to spoilage and fermentation processes.

20. Sleep and food and water are among the biogenic needs of the organism.

21. Sediment influx was assessed on an organic-, carbonate- and biogenic opal-free, dry-weight basis.

22. Isobutane occurs in crude oil and natural gas, except biogenic gas.

23. It is obvious that the the distribution of silica acid in interstitial water were affected by the contents of biogenic silica and aluminium, and aquiferous proportion as well.http://

24. The new test relies on the detection of a class of chemicals called nonvolatile biogenic amines.

25. Coalbed gases in Huainan coal field is a gas mixture resulted from thermogenic methane and secondary biogenic gas.

26. Based on this, the potential of thermogenic and secondary biogenic coalbed gases were analyzed and it is of practical significance for the coalbed gas exploration in the studied area.

27. Dihydroxyindole is an important intermediate of melanin, amino - acid, biogenic base and tryptamine.

28. By redesigning measurement processes, the assessment method of source rock for biogenic gas is established.

29. In this core, the vertical distributions of dinoflagellate cyst, organic carbon, carbon isotope and biogenic silica were studied.

30. The content of dissoluble organic matter in quaternary source rock of biogenic gas is about 2.
