Structure, ultrastructure and cation accumulation in quinoa epidermal bladder cell complex under high saline stress por Palacios, María Belén, Rizzo, Alex Joel, Heredia, Tatiana Belén, Roqueiro, Gonzalo, Maldonado, Sara, Murgida, Daniel Horacio, Burrieza, Hernán Pablo

“…Ionic content was quantifed with fame atomic absorption spectroscopy and with fame emission photometry. Results show that: (i) the number of EBCcs remains constant but their density and area vary with leaf age; (ii) stalk cells store lipids and exhibit thick walls, bladder cells present carotenes in small vesicles, oxalate crystals in vacuoles and lignin in their walls and both stalk and bladder cells have cuticles that difer in wax and cutin content; (iii) chloroplasts containing starch can be found on both stalk and bladder cells, and the latter also presents grana; (iv) plasmodesmata are observed between the stalk cell and the bladder cell, and between the epidermal cell and the stalk cell, and ectodesmata-like structures are observed on the bladder cell. …”

A thermostable laccase from Thermus sp. 2.9 and its potential for delignification of Eucalyptus biomass por Navas, Laura Emilce, Martinez, Fernando, Taverna, María Eugenia, Fetherolf, Morgan M., Eltis, Lindsay D., Nicolau, Veronica Viviana, Estenoz, Diana Alejandra, Campos, Eleonora, Benintende, Graciela Beatriz, Berretta, Marcelo Facundo

“…The incubation of steam-exploded eucalyptus biomass with LAC_2.9 and 1-hydroxybenzotriazole (HBT) as mediator changed the structural properties of the lignocellulose as evidenced by Fourier transform infrared (FTIR) spectroscopy and thermo-gravimetric analysis (TGA). However, this did not increase the yield of sugars released by enzymatic saccharification. …”
