Environmental Product Declarations for plants and soils: how to quantify carbon uptake in landscape design and construction?

The International Journal of Life Cycle Assessment - Currently, no clear guidance exists for ISO and EN standards of calculating, verifying, and reporting the climate impacts of plants, mulches,...     

Automatic assay of cellulase activity during fermentation

An automatic method using dyed cellulose as a substrate was developed to determine the solubilizing activity of a cellulase complex. The automatic analyzer was connected to a fermentor and enzyme activity was successfully assayed during fermentation. A useful sampling arrangement was developed and the analysis was sensitive enough to make a short reaction time possible. Cellulase production with Trichoderma viride was used as a model process.     

In vitro Clonal Multiplication of Acorus calamus L

Acorus calamus L (sweet flag) is a semi-aquatic perennial medicinal herb having a creeping and much branched aromatic rhizome. Rhizome buds cultured in MS basal medium supplemented with BAP (8.87μM) and NAA (5.37μM) at light intensity of 30μE m^?2 s^?1 and photoperiod of 12 h produced 8–10 multiple shoots by the eighth week of inoculation. Shoots could be rooted in MS basal medium without growth regulators. They were transplanted in sand and kept in shade for 4 to 5 weeks. 90–95% of the plants were established and were transferred to field after one month.
