    Abstract: A fusion protein including a phage tail-spike protein ΦAB6TSP and a signal indicator is provided. Also, a method of detecting bacteria having pseudaminic acid (Pse) is provided, including steps of contacting a sample with a phage tail-spike protein ΦDAB6TSP; and detecting a signal from the sample. The fusion protein and the method of detecting bacteria can be applied to a set of practical diagnosis and therapeutic alternative against Pse-coated antibiotic resistant pathogenic bacteria.

    Abstract: Disclosed herein are novel methods for hydrolyzing eggshell membrane (ESM). In one embodiment, the method includes cultivating thermophilic bacteria in a solution containing 1-10% (wt %) ESM to decompose the ESM into the ESM hydrolysate; wherein, the thermophilic bacteria grow on the ESM as their sole source of nutrient. In another embodiment, the method includes treating ESM with a keratinase in the presence of a reducing agent at a condition sufficient to produce the ESM hydrolysate, in which the keratinase, the reducing agent, and the ESM are present in a weight ratio of 1:120:600. The thus produced ESM hydrolysate is enriched in essential amino acids, collagen, peptides and glycosaminoglycans.

    Abstract: A fusion gene encoding M. taiwanensis WR-220 keratinase is disclosed. The fusion comprises: (a) a first DNA sequence encoding a protein secretion signal peptide, located at the N-terminus of the fusion gene; (b) a second DNA sequence encoding an inhibitory domain of M. taiwanensis WR-220 keratinase, linked in translation frame with the first DNA sequence; and (c) a third DNA sequence encoding a catalytic domain of M. taiwanensis WR-220 keratinase, linked in translation frame with the second DNA sequence, wherein the fusion gene is a non-naturally occurring chimeric DNA. Also disclosed are a method for preparation of the catalytic domain of M. taiwanensis WR-220 keratinase, and use of the M. taiwanensis WR-220 keratinase.

    Abstract: Disclosed herein are novel uses of avenaciolide derivatives and the preparation method of producing the same. The avenaciolide derivatives may suppress or inhibit the growth of gram-positive bacteria, including the notorious methicillin-resistant Staphylococcus aureus. Accordingly, the avenaciolides derivatives are potential lead compounds for the development of next generation antibiotics for the treatment of disease and/or disorders related to infection caused by gram-positive bacteria.
