Organic matter in space - An overview [PDF]
Proceedings of the International Astronomical Union, 2008 AbstractOrganic compounds are ubiquitous in space: they are found in diffuse clouds, in the envelopes of evolved stars, in dense star-forming regions, in protoplanetary disks, in comets, on the surfaces of minor planets, and in meteorites and interplanetary dust particles.

Bacterial Selection from Shrimp Ponds for Degradation of Organic Matters [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2007 Accumulation of ammonia, nitrite and hydrogen sulfide in a shrimp pond is generally caused by incomplete degradation of residual organic matters from overfeeding and from organic wastes released by shrimps.
