“…When applied to the soil, vinasse causes a series of changes in its chemical and physical characteristics, especially in pH, cation exchange capacity (CEC), organic carbon, water retention, electrical conductivity, porosity, and also affecting population and activity of microorganisms in the soil (España-Gamboa et al, 2011).…”

The selection of salinity tolerant bacteria may provide greater promotion of plant growth in soils with salt stress. This study aimed to isolate and select bacterial isolates of sugarcane, tolerant to salinity and plant growth promoters, and assess genetic diversity. To do so, endophytic root and rhizosphere of sugarcane, were isolated in culture medium with and without NaCl. The bacterial population density, the potential for biological nitrogen fixation (BNF), production of indole acetic acid (IAA), inorganic phosphate solubilization and quorum sensing molecule production were evaluated. Furthermore, the genetic diversity was assessed by Denaturing Gradient Gel Electrophoresis (DGGE) of nifH. Salinity tolerance tests were also conducted. There was no statistical difference in population density. As for the potential for BNF, IAA production, phosphate solubilization and quorum sensing molecule production, there was a high percentage of positive isolates. In the technique of DGGE nifH, the dendrogram showed high genetic variability. So there was the selection of bacteria that can contribute to the better development of sugarcane in saline soils.

“…Thus, the chemical properties of the residue depends on the raw material (biomass) used for the production of ethanol [15]. The chemical composition of sugarcane vinasse also varies depending on the each plant used in the production of ethanol as well as the subsequent distillation process.…”

The soil is a very complex and dynamic system and its contamination has become one of the main environmental concerns. Sugar-ethanol mills, for example, have a high hazard potential, mainly soil contamination, due to the production of different residues. The use of vinasse, a by-product of ethanol production, as fertilizer is a technically and economically feasible alternative. However, excessive quantities have been used, causing adverse changes in the soil. The present study was aimed at evaluating the toxic potential of vinasse in the Tradescantia pallida test system using the micronucleus test (Trad-MCN). Ten plants were exposed to ultrapure water as the negative control (NC), in MMS as the positive control (PC), raw vinasse (RV), and vinasse diluted to 50% (C1), vinasse diluted to 25% (C2), vinasse diluted to 12.5% (C3). The medium buds of each plant were used to assess the mutagenic effects based on the presence of micronuclei in tetrads. The results revealed that RV and C1 had a mutagenic potential compared to that of NC. The alterations observed suggest damage to the DNA of the test organism, which may not be reintegrated to the cell nucleus. The findings suggest caution in the application of this product to the soil despite this being an economically viable practice.

“…The general properties of the vinasse have been summarized in Table 2. The levels of vinasse application (0.5, 1, and 1.5 L m −2 ) were selected based on existing information application of vinasse for other purposes and other amendments, avoiding considerable environmental pollution due to high contents of N and K probably leading to high salinity and high density as well as feasibility of application and accessibility (Madejón et al, 2001;Gonzalez, 2005, 2006a, b;Tejada et al, , 2009Jiang et al 2010;Espanã-Gamboa et al, 2011). Three levels of 0.5, 1, and 1.5 L m −2 of vinasse were sprayed on the soil surface in three replications by a small manual pump and left for 24 h to increase the stability of the vinasse layer on the soil surface and mimic the natural conditions.…”

Abstract. Application of organic materials are well known as environmental practices in soil restoration, preserving soil organic matter and recovering degraded soils of arid and semiarid lands. Therefore, the present research focused on evaluating the effectiveness of vinasse, a byproduct mainly of the sugar-ethanol industry, on soil conservation under simulated rainfall. Vinasse can be recycled as a soil amendment due to its organic matter content. Accordingly, the laboratory experiments were conducted by using 0.25 m 2 experimental plots at 20 % slope and rainfall intensity of 72 mm h −1 with 0.5 h duration. The effect of vinasse was investigated on runoff and soil loss control. Experiments were set up as a control (with no amendment) and three treated plots with doses of 0.5, 1, and 1.5 L m −2 of vinasse subjected to simulated rainfall. Laboratory results indicated that vinasse at different levels could not significantly (P > 0.05) decrease the runoff amount and soil loss rate in the study plots compared to untreated plots. The average amounts of minimum runoff volume and soil loss were about 3985 mL and 46 g for the study plot at a 1 L m −2 level of vinasse application.
