“…First, we studied a microalgae-bacteria system consisting of photoautotrophic Chlorella vulgaris and aerobic Bacillus subtilis (Fig. 4c) for its capacity to bioremediate methyl orange 3,50 and amoxicillin 51 . In this microbial consortium, the microalgae fix carbon dioxide emitted from the bacteria into carbon sources whilst producing oxygen through photosynthesis for bacteria to respirate (Fig.…”

Living materials have emerged as systems bringing together material science and biology to allow the engineering and augmenting of living systems with novel functionalities. Bioprinting promises accurate control over the formation of such complex materials through programmable deposition of cells in soft materials, but current approaches had limited success on fine-tunning cell microenvironments while generating robust macroscopic morphologies. Here, we address this challenge through the use of microgel ink to bioprint functional living materials. Jammed core-shell microgels are microfluidically functionalized with cells in the aqueous cores which can promote the growth of both microbial communities and mammalian cellular spheroids, followed by an interparticle annealing to give covalently stabilized functional scaffolds with controlled microporosity that enhances the mass transfer of nutrients and metabolites. Different microbial consortia are immobilized in scaffolds towards versatile applications; more importantly, by compartmentalizing microbial consortia at microscale, the collective bioactivities of both consortia are significantly enhanced, shedding light on strategies to augment living materials with bioprocessing capabilities.

“…Seu cultivo não requer nutrientes adicionais, eles podem recuperar recursos de águas residuais e degradar antibióticos e poluentes farmacêuticos simultaneamente. Bioabsorção, degradação e acúmulo são os principais mecanismos envolvidos na remoção de poluentes por microalgas, diz Chandel et al (2022). O estudo do seu grupo de trabalho resumiu o cenário atual de remoção de antibióticos e farmacêuticos de águas residuais usando tecnologias mediadas por microalgas.…”

A água é essencial para a sustentabilidade da vida, sendo que apenas 2,5% do volume total é doce e disponível em reservas subterrâneas e superficiais, sendo responsáveis por fornecer água para abastecimento humano, desenvolvimento de atividades econômicas e manutenção da biodiversidade. O crescimento demográfico, a urbanização e a expansão das atividades econômicas agrícolas e industriais requerem a utilização cada vez maior de diferentes produtos químicos, que atingem os recursos hídricos por diferentes vias. Estas substâncias químicas, denominadas xenobióticos, são facilmente encontradas na água, comprometendo a qualidade e o seu fornecimento seguro. Além disso, tornou-se preocupação global por oferecer graves riscos para a saúde humana e manutenção da biodiversidade. O objetivo da pesquisa é verificar se a biorremediação é utilizada para tratamento de águas residuais e de abastecimento, visando fornecer subsídios para definir qual o melhor sistema de tratamento a ser utilizado de acordo com as características da água a ser tratada. Trata-se de uma pesquisa qualitativa, descritiva, tipo revisão integrativa de literatura. Os artigos selecionados apontam a biorremediação como uma alternativa sustentável e econômica para remover xenobióticos da água, utilizando diferentes organismos (microalgas, fungos, cianobactérias). Além disso, a fitorremediação mostrou-se também uma excelente opção para determinados xenobióticos.

Living materials bring together material science and biology to allow the engineering and augmenting of living systems with novel functionalities. Bioprinting promises accurate control over the formation of such complex materials through programmable deposition of cells in soft materials, but current approaches had limited success in fine-tuning cell microenvironments while generating robust macroscopic morphologies. Here, we address this challenge through the use of core-shell microgel ink to decouple cell microenvironments from the structural shell for further processing. Cells are microfluidically immobilized in the viscous core that can promote the formation of both microbial populations and mammalian cellular spheroids, followed by interparticle annealing to give covalently stabilized functional scaffolds with controlled microporosity. The results show that the core-shell strategy mitigates cell leakage while affording a favorable environment for cell culture. Furthermore, we demonstrate that different microbial consortia can be printed into scaffolds for a range of applications. By compartmentalizing microbial consortia in separate microgels, the collective bioprocessing capability of the scaffold is significantly enhanced, shedding light on strategies to augment living materials with bioprocessing capabilities.
