Special Issue Information

Dear Colleagues,

We are pleased to be inviting submissions to a Special Issue titled “Trends in Biochemical Processing Techniques”. Advances in biochemical processing are crucial for numerous industries, including pharmaceuticals, food, and environmental management. This Special Issue aims to highlight innovative techniques and emerging trends that are shaping the future of biochemical engineering and processing.

We welcome the submission of papers that explore optimization methods for biochemical processes, the development of new fermentation technologies, advanced purification methods for biomolecules, biocatalysis, and the integration of biotechnological systems. Additionally, we are interested in studies that address interdisciplinary approaches, the use of modeling and simulation tools, and the impact of new technologies on process efficiency and sustainability.

This Special Issue seeks to provide a comprehensive overview of the latest advancements, offering researchers and practitioners a platform on which to share their findings and insights. We especially encourage contributions that cover aspects such as the following:

  • The optimization of biochemical processes;
  • New fermentation technologies;
  • Advanced purification methods for biomolecules;
  • Biocatalysis and its applications;
  • Biotechnological systems in the pharmaceutical, food, and environmental industries;
  • Interdisciplinary approaches in bioprocessing;
  • Modeling and simulation tools in biochemical engineering;
  • The enhancement of process efficiency and sustainability through new technologies.

I am therefore pleased to invite you to contribute to this Special Issue, which aims to advance our understanding and application of biochemical processing techniques.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Processes is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Overcoming the oxidation stability of biodiesel has been a significant challenge, especially after an extended storage period. To test a major factor affecting biodiesel quality, eight different conditions consisting of water at a concentration of 500 ppm and tert-butylhydroquinone (TBHQ) concentrations of 500, 1000, and 2000 ppm, in combination, were added to palm biodiesel, with no-water-added treatment as the control. Samples were kept in dark storage and air-limited at room temperature for 52 weeks with an initial carbon residue of 0.05 wt%. Every sample was periodically taken for property examination, which included the percentage of fatty acid methyl ester (FAME), iodine value (IV), kinematic viscosity (KV), acid value (AV), and oxidation stability. The properties of the samples with 500 ppm of water-added biodiesel exhibited the most significant degradation, even though oxidation stability (starting from 43.37 h) remained higher than 10.00 h after 32 weeks. The IV dropped 48.43% from 49.92 to 25.56 g I2/100 g. The KV increased 6.14% from 4.56 to 4.84 cSt. The AV rose from 0.45 to 1.09 mg KOH/g. Biodiesel with 2000 ppm TBHQ added was stable for 22 weeks, with all properties under standard values. However, biodiesel in the same condition but with water contamination, its stability was reduced to 16 weeks. Full article
