The substrate used in all experiments consisted of soy cake, which is the byproduct of soybean oil extraction. The cake was milled and classified (Tyler 35-60) and then stored at -10°C in vacuum packs. Fermentation was... 

The use of soy cake is a promising substrate for lipase production. Even without optimization it is possible to achieve lipase activity as high as 21 U/g of dry cake, comparable with lipase activity obtained with other microorganisms and substrates. 

Even when they are technologically sound, however, bioproducts may turn out to be economically uncompetitive. The profitability of 1-lysine from one year to the next, for instance, depends on soy market prices. In the same way, the single cell proteins which BP produced in 1963 in Lavera from a petroleum base, using a process developed by France s Champagnat, never managed to compete with soy cakes for animal food. ICI has also just been forced to close down its 50,000-ton Pruteen unit in Billingham. 

Does the enterprise require the operation of grain elevators, feed mills, flour mills, rice mills, dust-pelletizing plants, dry corn mills, soybean flaking operations, and dry grinding operations of soy cake ... 

Oleivera et al. reported PHB production by R. eutropha using agro-industrial residues. The PHB productivity and content were 4.9mg/g medium in 60 h and 39%, respectively. Production was carried out using soy cake alone or supplemented with sugarcane molasses. The results obtained showed that the biopolymer obtained by SSF has similar properties as commercial PHB, except for the higher molar mass and the...

Secondly, soy cultivation was carried out in Brazil mainly for oil extraction and biodiesel production. The oil-extracted soy cake was used as animal fodder. Branford and Freris (2000) clearly mentioned that soy cultivation is a major reason for deforestation in Brazil. Researchers and forest activists believe that soy cultivation is mostly carried out for the soy cake, which is being used as food or fodder. Hence they argue that deforestation due to soy plantation cannot be attributed to biodiesel production. But in the actual case, a majority of soy cultivation is carried out solely for oil extraction and thereby biodiesel production (Goldemberg, 2007,2008).
