Opuntia ficus indica cladode as fermentation feedstock for lactic acid production by Lactobacillus acidophilus LA 5.

Published in Natural product research

Opuntia ficus-indica cladodes are by-products which contain high amounts of fibres, bioactive and functional compounds. Given their high annual productivity per hectare, cladodes represent a cheap and suitable substrate, usable for fermentation processes. We investigated their potential as a substrate for the growth and production of lactic acid fr...

Pretreated sugarcane bagasse matches performance of synthetic media for lipid production with Yarrowia lipolytica

Engineered strains of Yarrowia lipolytica with modified lipid profiles and other desirable properties for microbial oil production are widely reported but are almost exclusively characterized in synthetic laboratory-grade media. Ensuring translatable performance between synthetic media and industrially scalable lignocellulosic feedstocks is a criti...

Bacterial cellulose cookbook: A systematic review on sustainable and cost-effective substrates

Bacterial cellulose is a versatile material with applications in many industries. However, the widespread uptake of bacterial cellulose faces challenges including high production costs and lack of scalability. One approach to address these obstacles is the use of alternative substrates and media, compared to the Hestrin–Schramm (HS) media. By evalu...

Produção sustentável de etanol: avaliação da eficiência da hidrólise enzimática no amido de mandioca.

A crescente demanda por energia tem impulsionado o desenvolvimento de tecnologias mais eficientes e fontes renováveis. A mandioca destaca-se como alternativa para produção de etanol devido às suas vantagens agronômicas e características de processamento. Este estudo avaliou o efeito de diferentes tempos de hidrólise enzimática do amido em cultivare...

Alternatives végétales aux produits laitiers Leviers et enjeux pour l’innovation

Traditionnelles ou innovantes, les alternatives végétales aux produits laitiers accompagnent depuis les années 1980 les consommateurs occidentaux vers des régimes alimentaires plus sains et respectueux de l'environnement. Cet article a pour objectif d'aborder les leviers que sont les recettes, la technologie et la fermentation pour faire progresser...

Neurospora intermedia from a traditional fermented food enables waste-to-food conversion.

Fungal fermentation of food and agricultural by-products holds promise for improving food sustainability and security. However, the molecular basis of fungal waste-to-food upcycling remains poorly understood. Here we use a multi-omics approach to characterize oncom, a fermented food traditionally produced from soymilk by-products in Java, Indonesia...

High-Level Extracellular Expression of Hyaluronate Lyase HylP in Bacillus subtilis for Hyaluronan Degradation.

Published in Applied biochemistry and biotechnology

Hyaluronate lyase (HA lyase) has potential in the industrial processing of hyaluronan. In this study, HylP, an HA lyase from Streptococcus pyogenes phage (SPB) was successfully expressed in Bacillus subtilis. To improve the extracellular enzyme activity of HylP in B. subtilis, signal peptide engineering systematic optimization was carried out, and ...

Influence of process parameters on the environmental impact of 2,3-butanediol production by fermentation

Producing bio-based chemicals such as 2,3-butanediol using biological processes can play an important role in combatting global warming and addressing fossil oil depletion. To identify sustainable processes, this study sought to incorporate environmental considerations right from fermentation optimization at laboratory scale. As the literature revi...
