Composition useful for, among other things, culturing and enumerating microorganisms, and associated methods.

The technology provided herein relates to novel methods for producing lactic acid (L-lactic acid, D-lactic acid and D/L-Lactic acid) from starch containing material with extreme thermophilic bacterial cells belonging to the genus Caldicellulosiruptor, mutants thereof, isolated strains, microbial cultures, and microbial compositions. The novel methods are in particular suitable for the production of lactic acid from any carbon source, not limited to but especially useful for unmodified starch and/or starch-containing material.

The invention concerns the use of formate for increasing the thickness of a fermented milk-based composition, wherein the fermented milk-based composition is fermented by S. thermophilus. Furthermore the use of formate in a starter culture for increasing the thickness of a fermented milk-based composition is concerned, wherein the fermented milk-based composition is fermented by S. thermophilus

The present invention relates to a composition comprising bacteria of the Delftia genus, specifically a composition comprising Delftia tsuruhatensis as well as the bacteria itself for use in the prevention of malaria transmission and methods of using the compositions for reducing malaria and/or malaria parasite transmission.

The present invention relates to a Lactobacillus acidophilus KBL409 strain and uses thereof, wherein the Lactobacillus acidophilus KBL409 (deposit number KCTC 13518BP) strain according to the present invention reduces inflammation of the kidney, reduce the concentration of uremic toxins such as blood urea nitrogen, creatinine and p-cresol to protect the kidney, and thus may be usefully utilized for prophylactic and therapeutic applications of renal diseases including improving renal function and chronic renal failure.

Provided are a breast milk-derived Lactobacillus plantarum and use thereof. The breast milk-derived Lactobacillus plantarum, which was screened from healthy breast milk, is classified and named as Lactobacillus plantarum and has an accession number of CGMCC NO.19748. It has strong adhesion, has an inhibitory effect on 8 commonly known pathogenic bacteria, and is susceptible to 8 antibiotics, and also has strong acid resistance and bile salt resistance.

A method of preparing ammonium sulfate includes feeding biosulfur and ammonia produced during anaerobic fermentation into a sulfur-oxidizing microbial reactor to cause sulfur-oxidizing microorganisms to produce sulfuric acid through oxidation of the biosulfur and reacting the produced sulfuric acid with ammonia to produce the ammonium sulfate. A culture medium containing the produced ammonium sulfate and microorganisms can be used as fertilizers.

The disclosure discloses recombinant Bacillus subtilis for synthesizing guanosine diphosphate fucose and a construction method and application thereof. The recombinant Bacillus subtilis is obtained by intensively expressing guanylate kinase and nucleotide diphosphokinase genes and expressing exogenous fucokinase and phosphate guanylyltransferase genes in a genome of Bacillus subtilis 168. According to the disclosure, a bacterial strain for synthesizing the guanosine diphosphate fucose is obtained by reconstructing the Bacillus subtilis 168, with a volume of intracellular accumulation up to 196.15 g/L. According to the disclosure, by intensively expressing the guanylate kinase and nucleotide diphosphokinase genes, and enhancing the supply of intracellular GDP-L-fucose composition cofactors, the synthesis of the guanosine diphosphate fucose is promoted. The construction method for the recombinant Bacillus subtilis of the disclosure is simple and convenient to use, thus having good application prospects.

The present application refers to oral compositions comprising an effective amount of a Pediococcus acidilactici strain for use in regulating blood glucose levels, as well as for the prevention and/or treatment of hyperglycemia and/or a hyperglycemia-related condition. The application also refers to Pediococcus acidilactici CECT 9879, Pediococcus acidilactici CECT 9889 and Pediococcus acidilactici CECT 9967, and to these strains for use as probiotics, medicaments and for regulating blood glucose levels, as well as for the prevention and/or treatment of hyperglycemia and/or a hyperglycemia-related condition.

The present invention relates to novel sucrose negative (Suc−) Streptococcus thermophilus strains, compositions comprising said strains, uses thereof, methods for obtaining such strains and methods for the preparation of fermented food products using such compositions.
