A gene editing system of Candida viswanathii includes a Candida viswanathii, a first gene editing fragment and a second gene editing fragment. The first gene editing fragment successively includes a first homology arm and a screening gene. The second gene editing fragment is connected to a C-terminus of the first gene editing fragment and includes a second homology arm, a Cas9 expression cassette and a sgRNA cassette. The Cas9 expression cassette successively includes a Cas9 promoter, a Cas9 gene and three nuclear localization sequences. The sgRNA cassette successively includes a sgRNA promoter, a first ribozyme, a targeting sequence, a scaffold and a second ribozyme. The first gene editing fragment and the second gene editing fragment are constructed as a linear fragment for gene editing of a chromosome of the Candida viswanathii.

A sensor implanted in tissues and including a sensing layer is fabricated by mixing the signal transduction enzyme with non-reactive components including buffer salts and fillers, and spin coating the enzyme onto a substrate. The signal transduction enzyme is crosslinked by introducing the coated substrate in a vacuum chamber. In the chamber, a crosslinker evaporates and is deposited onto the enzyme, therefore crosslinking the enzyme.

The present invention relates to the field of microbial production of novel biosurfactants. More specifically, the present invention discloses the usage of a fungal strain such as the yeast Starmerella bombicola having a dysfunctional CYP52M1 cytochrome P450 monooxygenase and a dysfunctional FAO1 fatty alcohol oxidase for producing high amounts of so-called symmetrical bolaform sophorosides where both sophorose moieties are attached through a terminal glycosidic linkage to the hydrophobic linker. In addition, the present invention further discloses that the latter yeast can also be used to produce alkyl sophorosides and symmetrical bolaform glucosides.

There is provided a microbial cell for producing at least one omega-functionalized carboxylic acid ester from at least one alkane, wherein the cell is genetically modified to increase the expression relative to the wild type cell of (i) Enzyme E.sub.1 capable of converting the alkane to the corresponding 1-alkanol; (ii) Enzyme E.sub.2 capable of converting the 1-alkanol of (i) to the corresponding 1-alkanal; (iii) Enzyme E.sub.3 capable of converting the 1-alkanal of (ii) to the corresponding alkanoic acid; (iv) Enzyme E.sub.4 capable of converting the alkanoic acid of (iii) to the corresponding alkanoic acid ester; and (iv) Enzyme E.sub.5 capable of converting the alkanoic acid ester of (iv) to the corresponding omega-hydroxy-alkanoic acid ester, and wherein the cell does not comprise a genetic modification that increases the expression relative to the wild type cell of at least one of the following enzymes E.sub.20-E.sub.24 selected from the group consisting of: E.sub.20 Acyl-ACP thioesterase, of EC 3.1.2.14 or EC 3.1.2.22, E.sub.21 Acyl-CoA thioesterase, of EC 3.1.2.2, EC 3.1.2.18, EC 3.1.2.19, EC 3.1.2.20 or EC 3.1.2.22, E.sub.22 Acyl-CoA:ACP transacylase, E.sub.23 Polyketide synthase, and E.sub.24 Hexanoic acid synthase
