Publikováno v: International Journal of Polymeric Materials. 53:889-900
The aim of the present study was to examine the effect of time duration of bacterial cellulose (BC) biosynthesis as well as the culture medium composition on molecular parameters of the obtained polymer. It was found that the degree of polymerization

Autor: Stefan Boryniec, Grazyna Strobin, Andrzej Wlochowicz, Danuta Ciechanska, Henryk Struszczyk, Serafina Sobczak
Publikováno v: Polimery. 48:779-783
The article presents the results of studies on the effect of temperature and pH of the culture medium on molecular properties (M w and M n values, polydyspersity, radius of gyration) and on the productivity of biosynthesis of bacterial cellulose usin

Biodegradation of some natural polymers in blends with polyolefines
Autor: Stefan Boryniec, Maria Ratajska
Publikováno v: Polymers for Advanced Technologies. 10:625-633
The biodegradation of two-component blends containing synthetic and natural polymers was studied. Polyethylene, polypropylene and modified polyester were used as synthetic components. Three materials of natural origin, i.e. powdered cellulose, sodium

Physical and chemical aspects of biodegradation of natural polymers
Autor: Stefan Boryniec, Maria Ratajska
Publikováno v: Reactive and Functional Polymers. 38:35-49
The biodegradation of new polymeric materials of natural origin and of their mixtures with other natural and synthetic polymers was investigated. The processes of biodegradation were carried out in an aqueous and a soil medium in the presence of air.

Biotransformation of Cellulose: GPC Studies†
Autor: D. Ciechanska, Stefan Boryniec, Henryk Struszczyk, G. Strobin
Publikováno v: International Journal of Polymer Analysis and Characterization. 4:205-217
We are interested in developing a new manufacturing process for cellulosic fiber based on biotransformation of cellulose to make it soluble in NaOH solutions. The enzymes used are cel-lulases extracted from Aspergillus niger by deep fermentation of t
