11. Hydrolytic enzyme activities of extracted humic substances during the vermicomposting of a lignocellulosic olive waste

Abstract

Abstract: Humic substances and three hydrolytic enzymes (β-glucosidase, phosphatase and urease) were extracted by neutral sodium pyrophosphate from an olive waste (dry olive cake), alone or mixed with municipal biosolids, during a nine month vermicomposting process. Easily degradable compounds decreased during the vermicomposting process because of microbial consumption. When municipal biosolids were added to dry olive cake, microbial activity increased and the amounts of compounds extracted by pyrophosphate were three times lower than olive cake alone. In both instances, β-glucosidase, phosphatase and urease activities of the organic extracts either increased or remained the same after a nine month period of vermicomposting, thus suggesting that the humus enzyme complexes resisted microbial and earthworm attack. It is known that humus immobilised enzymes also remain active in soil environments, reactivating the nutrient cycles in soil. The use as amendments of vermicomposted olive cake, alone or when mixed with biosolids, could be a good alternative to reactivate the C, P and N-cycles in degraded soils for regeneration purposes.

13. Assessing the impact of composting and vermicomposting on bacterial community size and structure, and microbial functional diversity of an olive-mill waste

Abstract

The aim of this study was to couple biochemical and molecular methodologies for evaluating the impact of two recycling technologies (composting and vermicomposting) on a toxic organic waste. To do this, six enzyme activities controlling the key metabolic pathways of the breakdown of organic matter, real-time PCR assays targeting 16S rRNA genes, and denaturing gradient gel electrophoresis (DGGE) profiling-sequence analysis of PCR-amplified 16S rRNA fragments have been used to determine the functional diversity, bacterial number, and bacterial community structure, respectively, in a mixture of olive waste and sheep manure, and in the derived compost and vermicompost. Both the recycling technologies were effective in activating the microbial parameters of the toxic waste, the vermicomposting being the best process to produce greater bacterial diversity, greater bacterial numbers and greater functional diversity. Although several identical populations were detected in the processed and non-processed materials, each technology modified the original microbial communities of the waste in a diverse way, indicating the different roles of each one in the bacterial selection.

Abstract

Abstract: The chemical changes occurring in a cattle manure (CM) and a mixture of two-phase olive pomace and CM (OP+CM) after vermicomposting with Eisenia andrei for eight months were evaluated. Further, humic acid (HA)-like fractions were isolated from the two substrates before and after the vermicomposting process, and analyzed for elemental and acidic functional group composition, and by ultraviolet/visible, Fourier transform infrared and fluorescence spectroscopies. Before vermicomposting, the HA-like fractions featured a prevalent aliphatic character, large C contents, small O and acidic functional group contents, a marked presence of proteinaceous materials and polysaccharide-like structures, extended molecular heterogeneity and small degrees of aromatic ring polycondensation, polymerisation and humification. After vermicomposting, the total extractable C and HA–C contents in the bulk substrates increased, and the C and H contents, aliphatic structures, polypeptidic components and carbohydrates decreased in the HA-like fractions, whereas O and acidic functional group contents increased. Further, an adequate degree of maturity and stability was achieved after vermincomposting, and the HA-like fractions, especially that from OP+CM, approached the characteristics typical of native soil HA. Vermicomposting was thus able to promote organic matter humification in both CM alone and in the mixture OP+CM, thus enhancing the quality of these materials as soil organic amendments.
