FME Bio4Fuels’ Post

Check out a new paper from Daniel Waldschitz et al. The main aim of this study was to develop a cheap, robust, quantifiable and scalable bioproduction platform based on Spent Sulfite Liquor (SSL) as alternative to production of ethanol with Saccharomyces cerevisiae. Common simplifications, including the addition of expensive media components or energy/resource intensive detoxification steps, with low industrial relevance were entirely omitted. A minimal medium based on SSL for Corynebacterium glutamicum was developed, process kinetics and robustness were assessed and a successful scale-up was done. https://lnkd.in/dAHwGJMd #Corynebacterium #SpentSulfiteLiquor #ScaleUp

𝐓𝐰𝐨 𝐛𝐢𝐫𝐝𝐬, 𝐨𝐧𝐞 𝐬𝐭𝐨𝐧𝐞 𝐢𝐧 𝐠𝐫𝐞𝐞𝐧 𝐚𝐧𝐝 𝐬𝐮𝐬𝐭𝐚𝐢𝐧𝐚𝐛𝐥𝐞 𝐜𝐡𝐞𝐦𝐢𝐬𝐭𝐫𝐲! Excited to share our latest research using formic acid as a green reagent for two distinct methylation reactions, both catalyzed by Pd/In₂O₃. First, formic acid enables selective N-methylation of primary amides without additives, preserving the amide carbonyl and delivering high yields through a formylation/reduction pathway (DOI:  https://lnkd.in/eSAcDPqS, published yesterday in #chemcatchem). Second, formic acid serves as the sole carbon and hydrogen source to convert aromatic and aliphatic amines into methylamines via a formylation/transfer hydrogenation pathway, also without additives (DOI: https://lnkd.in/esaGrerE, published earlier in #CatalysisScienceAndTechnology). Using the same catalyst for both reactions showcases a versatile, sustainable approach to chemical synthesis. This work was carried out in the lab of Dr. Thibault Cantat with Dr. Caroline Genre at the LCMCE-CEA IRAMIS and Kassioge Dembélé #GreenChemistry #SustainableScience #Innovation #ChemicalResearch #PdCatalysis #FormicAcid #Methylation #heterogeneouscatalysis #SpreadYourWings

Bio-based stabilizers – shaping the future of polymer processing and durability is the title of the presentation by Dr. Metzsch-Zilligen Elke, head of the Research Department “Circular Additives and Compounds”, at the AMI Polyolefin Additives Conference on October 9, 2024. Find out more about chemical compounds known as (potential) process stabilizers and antioxidants that are obtained from plants and biowaste. But also about novel antioxidants based on the chemical functionalization of bio-based structures, with the aim of overcoming various limitations. She will also demonstrate significant improvements in the processing and long-term stabilization of polymers of various classes. Don't miss out on the latest developments in research on bio-based additives! https://lnkd.in/d6Xm9MqK #Polymers #BioBasedAdditives #Sustainability #CircularEconomy

I am very happy to share with you our newly published work in #ACS #Applied #Polymer #Materials, titled “Cross-Link of Telechelic Diacrylate Polymethylene-Glycol in Peptide-Based Fmoc-FF Hydrogel Matrices.” 👉 In this article, we investigate the possibility of generating interpenetrating networks based on Fmoc-FF by performing the cross-linking reaction of PEGDA monomers in supramolecular peptide hydrogels. This approach can enable the modulation of the final properties of the material, in terms of water behavior, topography, and stiffness. The obtained results indicate that the polymerization time, polymer length, and Fmoc-FF/PEGDA ratio play a crucial role in the material chemistry and, consequently, their potential application.

New and improved oxidation processes are highly sought after within academia and industry. Of specific interest is the direct oxidation of benzylic positions as this constitutes a key approach to manufacturing carbonyl-based fine chemicals. In our most recently paper, published in OPR&D, a continuous flow approach for the aerobic photo-oxidation of benzylic substrates to ketone and aldehyde products is presented. This approach offers several improvements over alternative oxidation methods due to the combined use of air as an oxidant and SAS (sodium anthraquinone-2 sulfonate) as a water-soluble photocatalyst. The use of greener and safer conditions together with process intensification principles renders this flow approach attractive for further industrial applications.

I am happy to share the recently published article. In this work, we have shown how pulping and bleaching can enhance bioethanol production. The way of lignin separation from black liquor has also been stated in this research work. Some of you may have an interest in this topic. https://lnkd.in/dHjpr9ci https://lnkd.in/d6-DitCb

One step closer to efficient and sustainable short-chain ester production with biocatalysis!

Global research since the 1920s has demonstrated that silicon fertilisers enhance plant growth, yield and quality. MaxSil, a highly potent silicon fertiliser, which has been certified as organic and biodynamic, has demonstrated these attributes in a decade of cropping trials across three states while remaining cost effective. #siliconfertiliser #fertiliser #organic #biodynamic www.maxsil.com.au

Assalamualaikum and hi everyone, During the first class of Biocatalyst (CBE687), my lecturer, Dr. Amizon Azizan has assigned me to conduct a survey on the topic ‘Biocatalyst’. The survey comprised 12 questions covering different aspects of biocatalyst, from basic concepts to enzyme mechanisms. From the results, my peers reflected a commendable level of understanding and familiarity with the subject. But what exactly is a Biocatalyst? In essence, biocatalyst are natural substances (most commonly enzymes) that accelerate chemical reactions without being consumed themselves. Unlike traditional chemical catalysts, which often rely on harsh conditions and produce harmful by-products, biocatalyst offer a cleaner, greener alternative. Here's why Biocatalyst is making waves: 🌟Sustainability: By harnessing the power of biological systems, biocatalyst enables processes that are inherently more sustainable. These bio-based catalysts operate under mild conditions, reducing energy consumption and minimizing waste. 🌟Specificity: Biocatalyst exhibit remarkable selectivity, catalyzing specific reactions with precision. This selectivity not only enhances efficiency but also reduces the need for additional purification steps, streamlining production processes. 🌟Safety: Unlike some chemical catalysts that may pose safety risks, biocatalyst are generally non-toxic and biodegradable, aligning with the principles of green chemistry and enhancing workplace safety. This survey gave me the chance to share knowledge with my friends about biocatalyst, and I want to thank everyone who participated! The poster below summarize the survey and few of its questions about biocatalyst. #biocatalyst #biocatalysis #bioprocess #chemicalengineering #industry #engineering #reactor #bioreactor #sustainability References: [1] Ager, D.
