A linear displacement isothermal amplification (LDIA) method and application thereof are by the present disclosure. The LDIA method of the present disclosure specifically starts the initial reaction of LDIA for four common primers of the template, including a pair of external primers (LOF and LOR) and internal primers (LIF and LIR), and an accelerating primer (LAR) may also be added in the reaction to form a short sequence product. The method provided by the disclosure greatly reduce the difficulty of primer design while maintaining the sensitivity and specificity similar to other isothermal amplification reactions such as loop-mediated isothermal amplification methods.

The present invention relates to an attenuated mutant strain of Salmonella comprising a recombinant DNA molecule encoding Wilms' tumor Protein 1. In particular, the present invention relates to the use of said attenuated mutant strain of Salmonella in cancer immunotherapy.

The present invention relates to an attenuated mutant strain of Salmonella comprising a recombinant DNA molecule encoding Mesothelin. In particular, the present invention relates to the use of said attenuated mutant strain of Salmonella in cancer immunotherapy.

Provided are delivery immunostimulatory bacteria that have enhanced colonization of tumors, the tumor microenvironment and/or tumor-resident immune cells, and enhanced anti-tumor activity. The immunostimulatory bacteria are modified by deletion of genes encoding the flagella, or by modification of the genes so that functional flagella are not produced, and/or are modified by deletion of pagP or modification of pagP to produce inactive PagP product. As a result, the immunostimulatory bacteria are flagellin.sup. and/or pagP.sup.. The immunostimulatory bacteria optionally have additional genomic modifications so that the bacteria are adenosine or purine auxotrophs. The bacteria optionally are one or more of asd.sup., purI.sup., and msbB.sup.. The immunostimulatory bacteria, such as Salmonella species, are modified to encode immunostimulatory proteins that confer anti-tumor activity in the tumor microenvironment, and/or are modified so that the bacteria preferentially infect immune cells in the tumor microenvironment, or tumor-resident immune cells, and/or are modified to induce less cell death in immune cells than in other cells. Also provided are methods of inhibiting the growth or reducing the volume of a solid tumor by administering the immunostimulatory bacteria.

Disclosed herein are methods and kits for quantifying the presence of a microorganism in a sample. Specifically, disclosed are methods for quantifying a pathogen in a sample, such as a food sample, to determine if the levels of pathogen present in the sample are within an acceptable range.

The present invention encompasses a recombinant bacterium capable of reducing tumor growth.

The present invention comprises a process to produce organic products from a single-carbon substrate; microbial compositions used in the process; and a process to isolate microorganisms for the process.

The antimicrobial effect of extracellular metabolite composition from Bacillus coagulans MTCC 5856 is described.

The antimicrobial effect of extracellular metabolite composition from Bacillus coagulans MTCC 5856 and composition comprising from about 61% w/w of thymol, about 38% of monolaurin and about 1% w/w of magnolol obtained from supercritical fluid extracts of Magnolia officinalis is described.
