The metabolic effects of native and transgenic hemoglobins on plants
- 1999

Ingår i: Trends in Biotechnology. - 0167-7799. ; 17:1, s. 4-21

Tidskriftsartikel (refereegranskat)abstract
- The strictly aerobic bacterium Vitreoscilla expresses a hemoglobin-like protein, VHb, when subjected to oxygen stress. When expressed in plants, this has several intriguing physiological effects, such as improving the overall growth rate, speeding germination and flowering, and increasing the productivity of certain oxygen-requiring metabolic pathways. Although the mechanisms behind the effects of VHb in heterologous hosts are not yet fully characterized, it has been suggested that VHb facilitates oxygen transport and/or storage. This hypothesis is supported by the kinetic properties of VHb, which allow very rapid dissociation of oxygen from the protein.

Tailoring the microenvironment of enzymes in water-poor systems
- 1991
-
Ingår i: Trends in Biotechnology. - : Elsevier BV. - 0167-7799. ; 9:1, s. 394-398

Forskningsöversikt (refereegranskat)abstract
- Biocatalytic systems using enzymes in organic solvents open up the possibility of performing a whole range of reactions which would not normally occur under physiological conditions. The ability to perform reverse hydrolysis, or to convert substances relatively insoluble in aqueous environments on a scale of practical value in commercial applications are among those reactions for which water-poor systems are appropriate.

Metal-binding proteins and peptides in bioremediation and phytoremediation of heavy metals
- 2001
-
Ingår i: Trends in Biotechnology. - 0167-7799. ; 19:2, s. 67-73
-
Tidskriftsartikel (refereegranskat)abstract
- The expression of metal-binding proteins or peptides in microorganisms and plants in order to enhance heavy metal accumulation and/or tolerance has great potential. Several different peptides and proteins have been explored. This review focuses on cadmium (Cd) because of the significant importance of this metal and because of its global presence in many food materials.

Protein adsorption to solid surfaces
- 1991
-
Ingår i: Trends in Biotechnology. - 0167-7799. ; 9:1, s. 201-208
-
Tidskriftsartikel (refereegranskat)abstract
- The phenomenon of protein adsorption to solid surfaces affects the performance of many materials and processes, in areas ranging from medicine to biochemical engineering. Controlling protein adsorption, from solutions of single proteins as well as from more complex mixtures, requires an understanding of the mechanism(s) by which it occurs. This, in turn, entails detailed characterization of both the protein and the solid surface and identification of those factors controlling the adsorption process.

Searching for process information in the aroma of cell cultures

- Aroma emissions from living cells can provide valuable information about the metabolic and physiological condition of those cells. Electronic noses are chemical gas-sensor arrays that use artificial neural network models to evaluate aromas. They can interpret the complex aroma information emitted from cultures of bacteria, yeast cells and animal cells. Potential applications for electronic noses range from medical diagnosis to industrial bioprocessing. Copyright (C) 2000 Elsevier Science Ltd.

The Potential Role of Immobilization in Plant Cell Biotechnology
- 1985
-
Ingår i: Trends in Biotechnology. - : Elsevier BV. - 0167-7799 .- 1879-3096. ; 3:11, s. 280-285
-
Tidskriftsartikel (refereegranskat)abstract
- It has long been hoped that the unique biosynthetic capacity of plants could be exploited in vitro using culture systems analogous to microbial fermentations. However, the characteristics of both the growth and metabolism of plant cells in vitro differ considerably from those of microbial cells and plant cell suspension culture systems have met with limited success. Immobilizing the cells creates a new set of options for the plant biotechnologist to explore. Improvements in some process criteria are apparent although evaluating the potential of immobilized plant cells for producing commercial compounds will only be possible when the biological problems have been overcome.
