The paper presents the floristic diversity of left bank Danube and canal network Krnjaca Borca settlements, as well factors that endanger it. 216 autochthonous allochthonous plant species were recorded in investigated area. A large number invasive have been observed spread rapidly easily forming stable populations displace native plants. Some them are: Amorpha fruticosa L., Robinia pseudoacacia...

This paper deals with comparative studies of bending behavior untreated and modified European beech (Fagus sylvatica L.), oak (Quercus spp.) black locust (Robinia pseudoacacia L.). The modification the woods included both ammonia treatment in combination mechanical densification. For each treatment, pure gaseous was used. investigations were conducted by means three-point tests. bulk density in...

This study was aimed at investigating the antimicrobial and antioxidant activity of ethanol extracts obtained from the leaves, seeds and sheaths of Robinia pseudoacacia. Total phenolic content (TPC, Folin–Ciocalteu method), antioxidant activity (trolox equivalent antioxidant capacity (TEAC) assay) and antimicrobial activity (agar disk diffusion method and broth dilution method) of the vegetativ...

A novel alpha-glucosidase with an apparent subunit mass of 59 +/- 0. 5 kDa was purified from protein extracts of Rhizobium sp. strain USDA 4280, a nodulating strain of black locust (Robinia pseudoacacia L), and characterized. After purification to homogeneity (475-fold; yield, 18%) by ammonium sulfate precipitation, cation-exchange chromatography, hydrophobic chromatography, dye chromatography,...

To investigate chemical and color changes of the polymeric constituents of black locust (Robinia pseudoacacia) wood during heat treatment, extractive-free wood flour was conditioned to 30% initial moisture content (MC) and heated for 24 h at 120 °C in either an oxygen or nitrogen atmosphere. The color change was measured using the CIELAB color system. Chemical changes of the wood components wer...
