The application focuses on five isolates that have shown probiotic potential for bacterial vaginosis treatment. Cultivation was performed in 300 mL bench-scale bioreactors, monitored for cell density, pH, lactate production, and glucose consumption. The media's carbon and nitrogen concentrations and costing were quantified. Though the medium's carbon concentrations were identical, the Soytone Medium had a higher carbon-to-nitrogen ratio than MRS (8.1 vs. 6.6). Four strains achieved higher cell densities and maximum specific growth rates in the Soytone Medium. The greatest benefit was shown for L. crispatus 70.6PA, which had a 45% higher final cell density. A cost analysis showed that the Soytone Medium was 44% cheaper than MRS Broth. It was thus confirmed that the proposed plant-based Soytone Medium is a viable and less expensive alternative for Lactobacillaceae cultures in which exposure to animal products was also avoided.

While NDT exhibits high activity toward natural nucleosides, its activity toward unnatural nucleoside analogs is significantly lower. Previously, the NDT mutant named fNDT(L59Q) was identified displaying 4.4-fold higher activity toward 2'-fluoro-2'-deoxyuridine (2FDU). In this study, molecular evolution strategies using error-prone PCR were employed to further generate mutant enzymes with enhanced activity toward 2FDU. After two rounds of mutational screening, two mutant clones that exhibited high activity against 2FDU were identified as fNDT-i1 (V52A) and fNDT-i2 (L28I), respectively. A double mutant, fNDT-i4, was subsequently constructed by combining the V52A and L28I mutations. Whole-cell-based activity measurements showed that fNDT-i4 exhibited 4.0- and 20.6-fold higher activity at 40°C and 50°C, respectively, compared to the wild-type NDT. The detailed characterization of the purified enzymes conducted under various conditions, including temperature, pH, thermal stability, and enzyme kinetics experiments, showed that fNDT-i1 and fNDT-i4 exhibited 3.1- and 3.7-fold higher catalytic efficiency, respectively than wild-type NDT. The L59Q mutation was identified as a key factor in improving the thermal stability, whereas the V52A and L28I mutations were critical for improving substrate affinity and reaction efficiency.

Using a sequence similarity network of putative glycosyltransferases, the thg biosynthetic gene cluster (BGC) was identified in the genome of Thermoanaerobacterium thermosaccharolyticum. Heterologous expression in Escherichia coli showed that the glycosyltransferase (ThgS) encoded in the BGC adds N-acetyl-glucosamine (GlcNAc) to Ser and Cys residues of ThgA. The peptide derived from ThgA, which we name thermoglycocin, was structurally characterized and shown to resemble glycocin F. In addition to two nested disulfide bonds also present in glycocin F, thermoglycocin contains a third disulfide bond creating a C-terminal loop. Unexpectedly, ThgA lacks the common double glycine motif for leader peptide removal by a C39-peptidase. Based on AlphaFold3 modeling, we postulated that cleavage between the leader and core peptide would occur instead at a GK motif, which was experimentally confirmed for an orthologous BGC from Ornithinibacillus bavariensis. Its structurally similar product termed orniglycocin was also produced in E. coli and carries two GlcNAc moieties on two Cys residues. The C39 peptidase domain of the peptidase-containing ATP-binding cassette transporter (PCAT) from this BGC removed the leader peptide after a Gly-Lys motif and the orniglycocin so produced demonstrated antimicrobial activity. This study adds to the small number of characterized glycocins, employs AlphaFold3 to predict the leader peptide cleavage site, and suggests a common naming convention similar to that established for lanthipeptides.

Enzymes with microorganisms are applied in the use of industrial biotechnology. Since the dawn of civilization, there are techniques like extraction and fermentation that use plant or bacterial enzymes as well as other byproducts. Enzymes, the natural catalysts, are intricately involved in many aspects of life. Enzymes pose remarkable specificity for their substrate, which implies that these metabolic cycles in a living cell need to be executed by a team working in collaboration. The major sources of these enzymes are yeast, some fungi and bacteria. Just like all living forms, microbes interact with their environment in which they must live in order to survive. A large number of microorganisms that are capable of producing great varieties of enzymes are important in the production of bread, cheese, yogurt, beer, and many other foods. One of the most widely used lipolytic enzyme is lipase from various sources including food and dairy industry, leather, detergent, pulp and paper, bioenergy and even pharma. With the latest innovation in biotechnology, the need for organisms that produce different commercially important lipases which other strains of lipases do is increasing.
