    Optimized models of landfill leachate processes that could lead to the production of fuel oils from the pyrolysis of plastics and cultivation of microalgae can be highly efficient and have sustainable activities. Studies using advanced oxidation processes in combination with biological processes showed to be efficient in treating leachate. The complexity of this type of waste, as well as the continuous modification of its properties due to local seasonality, prevents kinetic and thermodynamic studies to predict the steady state at the final disposal. Environmental management systems using Lean Six Sigma accompanied by process modeling and optimization tools, whether statistical or computational, generate reliable models. These models can reproduce reductions in contaminants by confirming the initial conditions of each leachate enabling the scale-up of the process. This chapter provides data survey, types of treatment, and models linked to optimization tools in wastewater decontamination processes from municipal solid waste. Also, this chapter includes the synthesis and proposal for treatment and management of the classification of garbage until the generation of leachate, aiming to contribute to future research in the area of leachate treatment.

    Lipases are hydrolases used in various sectors such as the food, pharmaceutical and chemical synthesis industries. In this study, epiphytic microorganisms were isolated from the Serra of Ouro Branco State Park (Minas Gerais, Brazil) and were subsequently evaluated for their ability to produce extracellular lipases. Among the 46 isolated strains, 25 presented positive results for lipase production in the agar plate screening assay. Two of these strains that expressed the highest diffusion halos, were genetically identified as Serratia marcescens and Pseudomonas fluorescens and catalogued in the Tropical Cultures Collection from the André Tosello Foundation/Brazil as CCT 7796 and CCT 7797, respectively. The fermentation growth kinetics indicated that the maximum extracellular lipase activities were achieved between 96 and 120h of cultivation. The highest lipolytic activity for both strains was observed at an optimum temperature and pH of 37°C and 7.0, respectively. At these conditions, the lipase activity detected in the crude enzymatic extract of both strains was close to 15.0 U/mL. We consider that these species are promising lipase producers for industrial applications.

  • Insights on the preparation and characterization of the poly(glycerol-co-malic acid) from renewable sources

    Biopolymers are sustainable materials derived from renewable sources that have relevant and industrially attractive properties such as biodegradability, biocompatibility and antimicrobial effect. Thus, these were the target of several experimental studies, widely published in the literature and used in our daily lives. This paper presents a preliminary investigation on the polyesterification of a malic acid/glycerol mixture in order to obtain the poly(glycerol-co-malic acid) to be evaluated as a bioadhesive. For this, different reaction conditions were evaluated by varying the concentrations of malic acid, glycerol and zinc chloride(II) as catalyst, carried out according to the central composite rotatable design. The polymerizations were monitored by acidity index, hydroxamic acid test and conversion rate and the obtained materials characterized by FTIR. Poly(glycerol-co-malic acid) was obtained in yields of 38 to 68% which show that such method is promising for obtaining this new biopolymer aimed as bioadhesive.

  • Evaluation of the biodegradation of phthalic contaminants originated from polyvinyl chloride commercial films

    The excessive use of phthalates (PHEs) plasticizers has promoted a serious environmental problem. This study evaluated the biodegradation of PHEs from polyvinyl chloride (PVC) film, aiming to mitigate damage to the environment. Therefore, 23 microorganisms were prospected and isolated from the Serra do Ouro Branco State Park (Minas Gerais, Brazil), where screening was carried out by growth in enriched microbial medium and esterase-activity was monitored by diffusion in solid agar. Three microorganisms were selected. Bacterium (I) presented the highest esterase activity, as evidenced in the diffusion tests in solid medium. Further, evidence of this is given by the biodegradation of PHEs into phthalic acid, because changes the acid concentration from 0 to 3.10 ± 0.07 mol L-1 and 28 % mass reduction of PVC film after 24 days. Furthermore, after six days of biodegradation the number of viable cells and ammonia concentration showed no significant change. This indicates that the survival of the Bacterium (I) cells is independent of ammonia consumption, but rather depends on PHEs consumption. The detection of the organic functions of -COOH and –COOR proved the biodegradation of PHEs by Bacterium (I), thus demonstrating its potential to be used in bioremediation of soils and rivers from PHEs contaminants.
