Increasing efforts have been done to find new applications for lignin. One of them is as a food additive, but its chemical nature makes it sensitive to browning which constitutes a major drawback for this type of lignin application. In the present study we are documenting how color stabilization of a commercial kraft lignin was achieved after the treatment with Penicillium chrysogenum var. halophenolicum. In addition the fungal capacity to remove lignin is studied together with the effect of its treatment on cytotoxicity of lignin. P. chrysogenum var. halophenolicum was able to transform lignin, ensuring its color stability for more than 24 months. Dynamic light scattering and atomic force microscopy showed that the fungus contributed to homogenize particle size and hydrodynamic properties in lignin suspensions without increase the toxicity over HeLa cells and human primary fibroblasts. These findings suggest new uses for kraft lignin after P. chrysogenum var. halophenolicum treatment providing an effective approach for improve color stability.Springer VerlagRepositório da Universidade de LisboaRemédios, MarleneCarvalho, Filomena AlmeidaEnguita, Francisco J.Cardoso, CarlosMartins, Ivo C.Santos, NunoLeitão, Ana Lúcia2019-03-25T11:47:17Z20162016-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10451/37674eng3 Biotech (2016) 6:1022190-572X10.1007/s13205-016-0414-xinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-11-08T16:34:56Zoai:repositorio.ul.pt:10451/37674Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T21:51:40.729970Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
