Kalman-based approaches for online estimation of bioreactor dynamics from fluorescent reporter measurements [PDF]

arXiv
We address online estimation of microbial growth dynamics in bioreactors from measurements of a fluorescent reporter protein synthesized along with microbial growth. We consider an extended version of standard growth models that accounts for the dynamics of reporter synthesis. We develop state estimation from sampled, noisy measurements in the cases of

The role of Moringa oleifera in the development of alternative biofuels, under the concept of an integral one‐tree biorefinery: A minireview

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The Moringa oleifera oil tree is commonly known as the ‘tree of life’ or the ‘miracle tree’ owing to its multiple benefits for humans. The different parts that make up this tree (leaves, seeds and bark) have been used to treat various ailments, diseases and wounds. However, in recent years this tree is being used by the scientific community to

Insights into Streptomyces coelicolor A3(2) growth and pigment formation with high‐throughput online monitoring

Engineering in Life Sciences, Volume 23, Issue 1, January 2023., 2023
Abstract Streptomyces species are intensively studied for their ability to produce a variety of natural products. However, conditions influencing and leading to product formation are often not completely recognized. Therefore, in this study, high‐throughput online monitoring is presented as a powerful tool to gain in‐depth understanding of the ...

Electrokinetic Flow Modeling Through Bone Scaffold [PDF]

arXiv
Fluid flow and mass transfer inside a bioreactor play a pivotal role in growing bone grafts, as cell proliferation is limited by the transport of nutrients and oxygen, as well as the removal of by-products from cells within the scaffold. Traditionally, perfusion bioreactors are used for tissue-engineered bone grafts.

Micro-Bioreactor Mimicking a Cellular Environment [PDF]

arXiv, 2006
We report that a cell-sized water droplet (CWD) with a diameter of several tens of microns can serve as a micro-biochemical reactor. Since the droplet inner surface is covered by a phospholipid layer, it provides an environment similar to that in living cells. The CWD is manipulated with laser tweezers and we monitor the time-development of biochemical

Fighting Antibiotic Resistance: Insights Into Human Barriers and New Opportunities

BioEssays, EarlyView.
Antibiotic resistance is a public health issue leading to the emergence of multi‐resistant bacteria. Human‐dependent factors are now driving the increase of resistance, notably through antibiotic misuse in human and animal health and environmental pollution.

Artificial microbial consortia for bioproduction processes

Engineering in Life Sciences, Volume 23, Issue 1, January 2023., 2023
Abstract The application of artificial microbial consortia for biotechnological production processes is an emerging field in research as it offers great potential for the improvement of established as well as the development of novel processes. In this review, we summarize recent highlights in the usage of various microbial consortia for the production

A chemostat model with variable dilution rate due to biofilm growth [PDF]

arXiv
In many real life applications, a continuous culture bioreactor may cease to function properly due to bioclogging which is typically caused by the microbial overgrowth. This is a problem that has been largely overlooked in the chemostat modeling literature, despite the fact that a number of models explicitly accounted for biofilm development inside the

"Oenodynamic": Hydrodynamic of wine swirling [PDF]

arXiv, 2011
A crucial step in wine tasting is the so called swirling, necessary to release the bouquet of the wine: a gentle circular movement of the glass generates a wave propagating along the glass walls, enhancing oxygenation and mixing. Although being used in a large variety of other applications (e.g. cells cultures in orbital shaken bioreactors) this motion
