The aim of this study was to extract a cellulose rich material from the agricultural residue of the processing of the ginger starch (GS) - the ginger bagasse (GB). The chemical composition of ginger are oleoresins, essential oils, and other components such as proteins, ash, minerals, and starch [1]. One of the by-products generated after the extraction of ginger starch consists of a fibrous material containing cellulosic fibers and residual starch. This material is here denominated ginger bagasse (GB). Ginger processing waste has been combined with ZnCl2 and H2SO4 to act as a bioabsorbent for water treatment from textile industries [2,3]. In this study, work the authors obtained this residue from rhizome and characterized it by FTIR, XRD and its thermal stability in nitrogen and air atmospheres. The initial results indicated success in obtaining an essentially cellulosic material with the presence of residual starch and thermal stability around 270 °C in inert atmosphere. Our future perspectives are the development of sustainable materials from biomass, attributing added value to an agro residue. |

Abstract - In apomixis, asexual mode of plant reproduction through seeds, an unreduced megagametophyte is formed due to circumvented or altered meiosis. The embryo develops autonomously from the unreduced egg cell, independently of fertilization. Brachiaria is a genus of tropical forage grasses that reproduces sexually or by apomixis. A limited number of studies have reported the sequencing of apomixis-related genes and a few Brachiaria sequences have been deposited at genebank databases. This work shows sequencing and expression analyses of expressed sequence-tags (ESTs) of Brachiaria genus and points to transcripts from ovaries with preferential expression at megasporogenesis in apomictic plants. From the 11 differentially expressed sequences from immature ovaries of sexual and apomictic Brachiaria brizantha obtained from macroarray analysis, 9 were preferentially detected in ovaries of apomicts, as con?rmed by RT-qPCR. A putative involvement in early steps of Panicum-type embryo sac differentiation of four sequences from B. brizantha ovaries: BbrizHelic, BbrizRan, BbrizSec13 and BbrizSti1 is suggested. Two of these, BbrizSti1 and BbrizHelic, with similarity to a gene coding to stress induced protein and a helicase, respectively, are preferentially expressed in the early stages of apomictic ovaries development, especially in the nucellus, in a stage previous to the differentiation of aposporous initials, as veri?ed by in situ hybridization. |
