Application of supercritical fluid technology in bioprocess engineering

100%

Malinowski J. , Jarzebski A.

Biotechnologia

1996

nr 3

87-96

An overview of the prospects for application of supercritical fluid technology in bioprocess engineering is given.Recent investigations on the application of dense gases in biocatalysis particles formation, separation and purificatiob of biologically active compounds are critically reviewed.

Some chemical and biological methods for the processing of waste activated sludges

100%

Kalembasa S. , Kalembasa D.

Biotechnologia

1997

nr 1

45-51

The addition of Cao to waste in ration 1:1 in relation to dry matter caused from one side partly sterilization of waste but from other big losses of nitrogen (about 50%) what decreased fertilizing value of waste and availibility of phosphor7us and heavy metals.Mixing of waste with others organic materials (sawdust pine barn, drops litter, beds after mushroom production) and vermicomposing of mixture allow on the production of very valuenable organo-mineral fertilizer and wormth biomass.

Biohazard and biosafety

88%

Chmiel A.

Biotechnologia

1993

nr 4

71-81

The development of techniques of DNA recombination in vitro is a basis for the discusion of biohazard and biosafety in laboratory experiments, technological processes and for the environment. After twenty years of experience in this field no hazardous incident was published and therefore we claim that genetic engineering is safe.However, there are different degrees of biohazard in biotechnology depending on the biological agents used, and therefore safety precautions for handling them were developed. The majority of microorganisms used in biotechnology, especially for food production, is harmless.For laboratory work with pathogenes or for their technological applications (e.g. in vaccine production) the techniques of containment are developed and introduced into the praxis. In some cases new technologies eliminate the biorisk in vaccine production: safe genetically engineered instead of pathogenes are utilized.It is necessary to state, that the biosafety problem is discussed mainly from the point of view of human needs.However, the most important question is genetic engineering and biotechnology applications for the military sector.
