Dr. Fernandez Lahore is Professor of Biochemical Engineering at the Department of Life Sciences & Chemistry at Jacobs University Bremen. His laboratory runs diverse projects in the fields of bioprocess engineering, enzyme technology / biocatalysis, and bioproduct downstream processing. In addition to offering regular courses serving our undergraduate students (Pharmaceutical Technology, Biorefining), Prof. Fernandez Lahore also teaches a very popular course – “Biotechnology: From Science to Business”.

Current projects under development in Prof. Fernandez Lahore’s Lab are related to:

  •     Bio production platforms based on filamentous fungi
  •     Design of novel materials for bioproduct downstream processing
  •     Bioprocess intensification
  •     Biochemical synthesis of APIs
  •     Biorefining of agricultural and forest byproducts

This work has been, and continues to be, funded by public and private agencies, including the DFG, BMBF, European Commission, and private foundation. The Lab has been specializing in actions supporting SMEs across Europe, applied R&D (mainly in cooperation with industrial partners), and translational science in the field of biotechnology. Many projects are coordinated by Prof. Fernandez Lahore from Jacobs University.

Funded Projects: 

Modern biotechnology heavily depends on the availability of efficient processes, which should be able to generate competitive products (or services) in terms of quality and cost. A critical assessment of current bioprocess technology will reveal that fermentation procedures are already in a phase of technological maturity and that many successful approaches to heterologous protein expression are being employed. However, product recovery and purification (also referred as downstream processing) still poses a number of important challenges. For example, downstream operations cost usually represents more than 50-80% of the total processing cost. Thus, it comes as no surprise that optimisation of the later steps is considered a central element in appropriate bioprocess design. Unfortunately, and probably due to the common practice of expressing proteins at laboratory scale without any concern on how the product will be purified at a larger scale, downstream processing strategies are usually neglected until a later phase of process development. This is a major reason for increased processing cost and eventually the reason for product failure in the market (Datar and Rosen, 1990).
 
The picture described above has fostered the integration between unit operations devoted to product recovery and purification. The mentioned concept materialises through the introduction of newly designed downstream process technologies which replaces a number of more traditional unit operations, like precipitation, centrifugation/filtration, and column chromatography among others. Efforts to perform integrative purification have been made using aqueous two-phase partitioning, membrane adsorbents or fluidised materials for protein capture (Brandt et al., 1988; Kula, 1990; Hjorth, 1997). Moreover, bioprocess integration is a term also used to describe the need to couple properly upstream and downstream operations, something that quite often is left to chance with dramatic consequences (Wielen and Luyben, 1992).
 
Within the scope of this project, a meta-integration strategy (refer to Fig. 1.) is proposed by full cross-optimisation from gene to product. The prefix meta- is thus "used with the name of a discipline to designate a new but related discipline designed to deal critically with the original one" (Webster Dictionary). As oppose to the standard practice we will start choosing the downstream operation. This will be an adsorption step based on the well known principle of ion exchange (IEX). Chromatography (or the simpler finite batch adsorption) on anion or cation exchangers is a widespread technique for large-scale protein purification, because of economy, robustness and suitability for cleaning in place (CIP) and/or sanitisation in place (SIP). However, ion exchange is usually regarded as a low-to-moderate-resolution purification step. It also requires concentrations of the target species above a certain threshold in order to effectively bind them (Skidmore et al., 1990). On the other hand, we should remember that packed-bed adsorption does not tolerate the presence of particles in the feedstock thus imposing the need for extensive clarification to avoid system clogging and concomitant back-pressure development (Thömmes, 1997). It is clear that a well designed integrative procedure will attempt to simultaneous solid-liquid separation, product selective isolation and de-watering (target concentration). All those potential drawbacks of the chosen core technology (i.e., IEX) are overcome by taking action towards full cross-optimisation of the whole process: a) Use of gene technology to facilitate product purification, i.e. alteration of protein isoelectric point (pI) by addition of charged amino acid residues; b) Selection of the right system with potential to achieve high levels of foreign gene expression, i.e. the baculovirus expression vector system (BEVS); c) Insect cell cultivation in bioreactor(s) for mass protein production, i.e. Stirred Tank vs. Airlift reactors; and d) IEX system, i.e. adsorption on modified hollow fiber membranes vs. adsorption on fluidised and classified matrices.
