TL;DR: In this paper, the possibility of obtaining vanillin from bioconversion of ferulic acid derived from enzymatic hydrolysis of wheat bran was explored, and a vanillin molar yield of 50% was obtained, but most of the vanillin produced was reduced to vanillyl alcohol.

TL;DR: The goal of this research is to evaluate the potential of using membrane based solvent extraction for the recovery of vanillin obtained by bioconversion of ferulic acid in view of the on-line extraction from theBioconversion broth, thus coupling bioconversions and separation.

TL;DR: In this article, the impact of the application rate of biosolids from municipal sewage sludge on soil functionality was studied, where the products were applied at increasing doses, 50 (1/1/v/v), 150 (3/3/v)/v), and 300 (6/6/v) on a sandy loam soil.

TL;DR: In this article, two different biosolids were obtained by chemical analysis and compared with a conventional green manure plus mu- nicipal solid waste and municipal sewage sludge with rice husk.
Abstract: Two different biosolids were obtained compost- ing anaerobic (A) and aerobic (B) municipal sewage sludge (SS) with rice husk. Higher amounts of SS (1:1 v/v) could be used in this composting process than in conventional ones. The two biosolids were characterized by chemical analysis and compared with a conventional green manure plus mu- nicipal solid waste and municipal SS compost. The effect of these products on soil functionality was studied in a 14- week incubation experiment by their addition to two different soils (silty clay—Ustic Endoaquert—and sandy loam—Aquic Xeropsamment). The total organic C ranged from 20 to 26 % and total N from 1.6 to 2.5 % in the two biosolids. The most relevant difference was due to dissolved organic C that was lower in the anaerobic biosolid (1 mgCkg −1 ) than in the other prod- ucts (5- 6m gCkg −1 ). The total trace elements (Cd, Cr, Cu, Ni, Pb and Zn) contents were under the limits fixed by the European legislation for soil application of SS (EC Directive 86/278/EEC, 1986). The three biosolids did not show strong negative effects on soil functional- ity during the incubation experiment, although some significant differences were found. The aerobic biosolid B mainly increased cumulative N release, microbial activity, basal respiration rate, microbial biomass-C-to- total organic C ratio, β-glucosidase, alkaline phospho- monoesterase and aryl-sulphatase activities. The anaero- bic one (B) decreased basal respiration rate, microbial biomass-C-to-total organic C ratio and aryl-sulphatase activity. DTPA soil bioavailable heavy metals were not affected by biosolids additions.

TL;DR: A review of the current status of aromatics biodegradation can be found in this paper, where the authors briefly discuss the catabolic mechanisms and describe the current state of the bio-films and their applications in biodegradable aromatic compounds.
Abstract: Biodegradation can achieve complete and cost-effective elimination of aromatic pollutants through harnessing diverse microbial metabolic processes. Aromatics biodegradation plays an important role in environmental cleanup and has been extensively studied since the inception of biodegradation. These studies, however, are diverse and scattered; there is an imperative need to consolidate, summarize, and review the current status of aromatics biodegradation. The first part of this review briefly discusses the catabolic mechanisms and describes the current status of aromatics biodegradation. Emphasis is placed on monocyclic, polycyclic, and chlorinated aromatic hydrocarbons because they are the most prevalent aromatic contaminants in the environment. Among monocyclic aromatic hydrocarbons, benzene, toluene, ethylbenzene, and xylene; phenylacetic acid; and structurally related aromatic compounds are highlighted. In addition, biofilms and their applications in biodegradation of aromatic compounds are briefly discussed. In recent years, various biomolecular approaches have been applied to design and understand microorganisms for enhanced biodegradation. In the second part of this review, biomolecular approaches, their applications in aromatics biodegradation, and associated biosafety issues are discussed. Particular attention is given to the applications of metabolic engineering, protein engineering, and “omics” technologies in aromatics biodegradation.
