A problem to be solved by the present invention is to provide a novel material increasing antimicrobial peptide production from epithelial cells and thereby having an infection-preventing effect. The present invention provides a composition for promoting antimicrobial peptide production containing lactic acid bacteria of the genus Lactobacillus as an active ingredient. The present invention also provides a composition for promoting antimicrobial peptide production containing a component derived from a Lactobacillus bacterial cell as an active ingredient. The present invention further provides a composition for promoting antimicrobial peptide production in which the component derived from a bacterial cell is one or more selected from the group consisting of an S-layer protein and a degradation product of the S-layer protein.

Disclosed are biomaterials, including engineered living materials (ELMs), comprising a plurality of microbial cells, wherein the material has a Young's Modulus of at least 5 Gpa; and methods of fabricating said biomaterials.

The present invention is directed to the direct application of beneficial or probiotic bacteria to the skin for maintenance of a healthy skin microbiota and to help restore an unbalanced skin microbiota. The application is based on the use of selected Lactobacillus strains as anti-pathogenic agents, in particular L. plantarum, L. pentosus and/or L. rhamnosus, against common skin pathogens, whereby produced acids such as lactic acid are important antimicrobial factors.

The disclosure relates to methods for decreasing feed conversion ratios in fowl through administering isolated microorganisms to the fowl. In particular aspects, the disclosure provides methods of decreasing feed conversion ratios in fowl through administration of a Bacillus sp. to the fowl. The disclosure further relates to isolated microorganisms and compositions comprising the same.

Provided are vesicles derived from bacteria of the genus Weissella and a use thereof. The present inventors experimentally identified that vesicles derived from bacteria of the genus Weissella effectively suppress the secretion of inflammatory mediators from pathogenic vesicles inducing inflammation. Thus, it is expected that the vesicles derived from bacteria of the genus Weissella according to the presently claimed subject matter will be advantageously used for the purpose of developing a composition for preventing, alleviating, or treating inflammatory diseases.

The present invention relates to a composition suitable for preparing a dairy product comprising at least one starter culture and a Lactobacillus rhamnosus strain capable of imparting onto the dairy product an enhanced creamy flavor without affecting the rheology negatively, the fermentation time or the post-acidification of the dairy product. The present invention further relates to processes for preparing a dairy product, such as a low-fat yogurt or cheese, which has a high content of diacetyl. A Lactobacillus rhamnosus strain useful for preparing such dairy product is also part of the present invention.

The present invention relates to novel strains of Lactobacillus as well as preparations and compositions, such as fermentation broths, protective cultures, final food or feed product with Lactobacillus alone or in combination with bacteria of the genus Propionibacterium. The present invention further relates to methods for the controlling of growth of a contaminant, such as a bacteria, yeast or mould by using these novel strains of Lactobacillus.

The present disclosure provides an antimicrobial composition as well as a process using same to limit microbial activity in a yeast medium. The antimicrobial composition includes at least one weak acid, optionally in combination with an acid stable bacteriocin and/or an antibiotic. The antimicrobial composition can be used for propagating yeasts and for making a fermentation product. The present disclosure also provides yeasts and lactic acid bacteria that can be used with the antimicrobial composition.

An object is to provide lactic acid bacteria that can be applicable to feed, fertilizers, live bacterial preparations, probiotics, etc. The lactic acid bacteria are identified and deposited under the accession numbers of NITE (National Institute of Technology and Evaluation) P-02313, NITE P-02314, NITE P-02490, NITE P-02491, and NITE P-02492. In addition, another object is to provide feed, fertilizers and live bacterial preparations containing the lactic acid bacterium/bacteria of the invention. According to studies, it is confirmed that the lactic acid bacteria are proliferated in animals including human, plants, etc. without being destroyed. According to studies, it is also confirmed that the lactic acid bacteria are proliferated in water, soil, etc. without being destroyed. Therefore, the lactic acid bacteria can be widely applicable in feed, fertilizers, live bacterial preparations, etc.

Fermentation by-products can be used in feed to provide nutrients to animals. The present disclosure concerns a process for modulating the nutritional content in a whole stillage. The process includes fermenting a biomass in the presence of a recombinant lactic acid bacteria (LAB) cell and a yeast with a biomass and recuperating the whole stillage once the fermentation has been completed. The recombinant LAB is capable of expressing one or more first heterologous enzyme for converting the biomass into the fermentation product.
