Leaching of toxic elements from secondary alkaline lead slag and stabilized/solidified products
(Springer, New York, 2019)
Secondary alkaline lead slag (SALS), generated during lead-acid batteries recycling, is a hazardous waste due to its high reactivity, solubility, and migration of toxic elements. After pulverization caused by storage under ...
Enzyme production by solid-state fermentation on soybean meal: A comparative study of conventional and ultrasound-assisted extraction methods
(Wiley, Hoboken, 2019)
Protease, cellulase, and alpha-amylase producing Bacillus subtilis strain was cultivated by solid-state fermentation technique using soybean meal as a substrate. The aim of the present study was to establish a highly ...
Cryopreservation of Serbian autochthonous Prunus spp. by droplet-vitrification
(Springer, New York, 2015)
In vitro shoot tips of Serbian autochthonous plums 'Sitnica' (Prunus domestica L.) and 'Crvena Ranka' (Prunus insititia L.) were tested for recovery after cryopreservation using the droplet-vitrification technique. After ...
