The objectives are to use ground penetrating radar (GPR) to: (a) find a suitable length and location for a future underground dam; and (b) model the shape and estimate the volume of its water reservoir. Radargrams were obtained in a 0.85-ha area in northeastern Brazil along five survey lines parallel to, and eight lines transverse to the slope, starting from the proposed location of the dam. The 13 radargrams were pre-processed and migrated. The terrain surface and the top of the regolith delineated in the radargrams were interpolated, plotted in 3D showing the shape of the water reservoir, and used to estimate its volume. From the radargrams, the future dam should be 45 m longer and centered 22 m south of the proposed location, increasing the water reservoir by 50% to a total of 6 million L. By assessing the terrain surface and regolith, the GPR allows to adjust the length and position future underground dams and assess their water reservoir shape and volume non-invasively. |

Interest in the production of renewable chemicals from biomass has increased in the past years. Among these chemicals, carboxylic acids represent a significant part of the most desirable bio-based products. Xylonic acid is a five-carbon sugar-acid obtained from xylose oxidation that can be used in several industrial applications, including food, pharmaceutical, and con-struction industries. So far, the production of xylonic acid has not yet been available at an industrial scale; however, several microbial bio-based production processes are under development. This review summarizes the recent advances in pathway characterization, genetic engineering, and fermentative strategies to improve xylonic acid production by microorganisms from xylose or lignocellulosic hydrolysates. In addition, the strengths of the available microbial strains and processes and the major requirements for achieving biotechnological production of xylonic acid at a commercial scale are discussed. Efficient native and engineered microbial strains have been reported. Xylonic acid titers as high as 586 and 171 g L −1 were obtained from bacterial and yeast strains, respectively, in a laboratory medium. Furthermore, relevant academic and industrial players associated with xylonic acid production will be presented. |
