Organic source

Organic material A material from an organic source. 

Slime-Forming Bacteria. Several forms of bacteria produce a slimy capsule under certain environmental conditions. These organisms are heterotrophic, that is, they obtain their energy from organic sources such as sodium lactate. The reaction is... 

The growth of cells on a large scale is called industrial fermentation. Industrial fermentation is normally performed in a bioreactor, which controls aeration, pH and temperature. Microorganisms utilise an organic source and produce primary metabolites such as ethanol,... 

The mechanism for this photoreaction has not been elucidated, although it has been ascertained that these products are not observed in the dark reaction with acetone under the same conditions as used in the photolysis. The source of the isopropylidene unit is undetermined, but since all extraneous organic sources were excluded in the experiment, it seems clear that it originates from the azulene system itself, presumably from the five-membered ring.

Complete blood cell count (CBC) may identify anemia, which may suggest blood loss and an organic source for Gl symptoms. 

At the moment, Soil Association regulations permit organic pig producers to feed 30% of the daily ration from non-organic sources. This means that the organic pig producer has to feed 70% of the daily ration as organic feed, and this is normally more expensive. The 30% non-organic has to be from permitted sources. 

Water extendible metalworking fluids are susceptible to contamination by microorganisms, used coolants in particular can be very easily colonised. Metalworking systems are open to the air and are constantly inoculated with micro-organisms. Sources of inoculum include ... 

Their selective binding interactions with different 0-, N- and S-donors both from inorganic or organic sources affecting solubility and complex formation (see Section 2.19).

Biofuel Fuel derived from organic sources, e.g., biogas, biomass and the biodegradable fraction of waste. The use of biofuel is neutral in terms of carbon dioxide emissions.

A typical hydrothermal vent system. Included are basal mounds of mineral precipitates, pillow basalts, a black smoker, and various vent organisms. Source From Haymon, R. M. and K. C. Macdonald (1985). American Scientist, 73, 441 49.

Leave for three months if from an organic source, otherwise six months to allow for any unwanted pollutants to break down. If based on a bedding material of wood shavings rather than straw, at least a year will be needed, and even then the end product is best used only as a mulch.

First, organic sources of nutrients or organic pest control measures are often more expensive than traditional sources. Second, marketable yields are frequently less with organic production. Lastly, organic produce may not store or ship as well as traditional produce. 

Monomer recovery Decant water layer Dissolved and separable organics. Source of high BOD and COD discharges... 

Mild thrombocytopenia - Mild thrombocytopenia may remain stable or reverse even if heparin is continued. However, closely monitor thrombocytopenia of any degree. If a count falls below 100,000/mm or if recurrent thrombosis develops, discontinue heparin. If continued heparin therapy is essential, administration of heparin from a different organ source can be reinstituted with caution. 

Figure 6.28 Metabolism of diethylstilboestrol via an epoxide intermediate. This potentially reactive intermediate may show an affinity for the estradiol receptor and thereby accumulate in oestrogen target organs. This may facilitate reaction with DNA in these organs. Source. From Ref. 10.
