Abstract
In today’s bio-based industry, lipase-catalyzed processes hold eminent
commercial worth, yet their use is restricted owing to low yields, high
production cost, inconsistent reproducibility, and poor performance in
native form. Cloning and expression of multiple lipase genes in various
systems have been investigated in order to produce enzymes for the food
and detergent industries more cheaply since the development of
recombinant DNA technology. The identification of novel lipases is still
hampered by the rather difficult expression of these enzymes. The
expression of lipases still requires a case-to case optimization.
However, the unbiased choice of the appropriate promoter system and host
for a specific protein of interest remains difficult. Here, we concisely
expressed TLIP (Lipase from Thermomyces lanuginosus; mainly used
in the detergent industry) in the frequently used conventional and
alternative host systems, with their unique features, along with
different promoters (T5, T7, aprE and hp4d) to produce recombinant
products. Screening of expression was done among both prokaryotic (
Escherichia coli, Bacillus subtilis) and eukaryotic (
Yarrowia lipolytica) hosts consisting of both intracellular and
secretory expression. E. coli (BL21 Shuffle) and Y.
lipolytica (extracellular) were found to be the best expression systems
for lipase production.
