Technique to Obtain Mitotic Chromosomes of Conyza bonariensis L. Cronquist (Asteraceae)  [PDF]
Juliana Maria de Paula, Cecília Alzira Ferreira Pinto-Maglio
American Journal of Plant Sciences (AJPS) , 2015, DOI: 10.4236/ajps.2015.69145
Abstract: Cytogenetic analysis requires cytological preparations that unequivocally reveal the chromosome number and permit optimal visualizations of chromosome morphology for the construction of karyotypes and ideograms. Chromosomal characterization is possible only by establishing these two parameters. To cytogenetically characterize the weed Conyza bonariensis (L.) Cronquist (Asteraceae), it was necessary to improve cytological analysis techniques to obtain optimal results. This species belongs to a genus whose plants have wide phenotypic plasticity. These plants can be morphologically differentiated by other types of analysis, and thus the application of this technique will serve as a reference for cytogenetical analysis of other groups of plants that have cytogenetic characteristics similar to those of C. bonariensis. The methodology described here highlights three main protocol steps: 1) root tip collection from newly germinated seed radicles and from young root tips of mature plants, 2) pretreatment of meristems with antimitotic agents, both isolated and combined, and 3) acid and enzymatic hydrolytic processes.

Food and Nutrition Sciences (FNS) , 2013, DOI: 10.4236/fns.2013.45075

Proteins recovered were obtained from Whitemouth Croaker (Micropogonias furnieri) byproducts and their physico-chemical and functional properties were evaluated. The proximate composition, presented 8.64% ± 0.10% of moisture, 85.33% ± 0.12% of protein, 2.69% ± 0.09% of ashes and 2.16% ± 0.12% of lipids, in dry basis. The highest solubility was obtained in pH 11 (93.24%), the maximum water holding capacity was presented at pH 11 (25.71 mL H2O/gprotein), the oil holding capacity was 13.71 mL/gprotein and the digestibility in vitro was 91.32% ± 0.15%. The electro-phoretic profile was observed typical of the myofibrillar proteins, with the appearance of the heavy chain of myosin (220 kDa) and actin (50 kDa). The results show that the products of low commercial value of fish that are usually used for the production of animal feed or simply discarded, contributing to environmental pollution, may be used to produce products with a greater added value.

Abstract: biodiesel was created as a solution for a great economic and enviromental problem of petroleum, a resource with sustainable characteristics. but its production still needs optimization, because it uses a lot of water and generates a large volume of this residue, which appears improper to disposal without correct treatment. this work propose an economic, viable and efficient way to treat the biodiesel purification water, not only aiming at a proper disposal, but the reuse as input in the process, generating a large industrial economy, and greater environmental progress. for both treatment uses the electrofloculation technique.
