Última Effect of Nutrient Sources on the Alginate Accumulation in the Culture Liquid of Azotobacter vinelandii D-05 and Obtaining Biocomposite Materials BABT Revin,Victor Vasilevich; Kostina,Elena Gennadievna; Revina,Nadezhda Victorovna; Shutova,Vitalina Victorovna. ABSTRACT Using the classic biotechnological methods, the dependence of A. vinelandii D-05 culture alginate production from the media carbon and nitrogen content was investigated. The maximal alginate production was observed during cultivation bacterium in the medium with 2 to 4% of sucrose, but the maximal growth was found in the medium with 4% glucose. It was found that for the alginate production the optimal nitrogen contents could take from 0.05% yeast extract (carbon: nitrogen ratio 168:1). For the first time we demonstrated possibility the A. vinelandii growth during the cultivation in a medium with molasses (a by-product of sugar production) and the significant polysaccharide production (16.6 g/l) was obtained. It was established, that A. vinelandii... Tipo: Info:eu-repo/semantics/article Palavras-chave: Azotobacter vinelandii; Alginate; Nutrient medium; Carbon: nitrogen ratio; Biocomposite. Ano: 2018 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1516-89132018000100407 'Ponkan' mandarin (Citrus reticulata Blanco) immature fruits storage Ciência e Agrotecnologia Pasqual,Moacir; Dutra,Leonardo Ferreira; Araujo,Aparecida Gomes de; Figueiredo,Milene Alves de. The aim of this work was to evaluate the effect of 'Ponkan' mandarin (C. reticulata) x 'Pêra' sweet orange (C. sinensis) immature fruits storage and sucrose concentrations on embryos in vitro culture. Fruits with 3 to 4 cm in diameter were harvested and placed inside black polyethylene bags with lateral openings and stored at 5±1ºC during 135 days. Every 15 days a sample was removed, its embryos were excised and individually inoculated in test tubes containing 15 mL of MS medium (Murashige & Skoog, 1962) with sucrose (0, 1.5, 3, 6, 12, 18 and 24 g L-1) and 0.3 mg L-1 GA3 and 1 g L-1 activated charcoal. Those treatments rested 48 hours in the dark and later in a growth room at 27 ± 1ºC with a 16-h photoperiod and 32 µmol m-2 s-1 light intensity....
