The present disclosure discloses a method for removing TBBPA in water, a microbial strain and a microbial agent, wherein the microbial strain is a domesticated Burkholderia cepacia strain, which is named Y17 with a conservation number GDMCC No. 62153. The microbial agent and the method for removing TBBPA in water with the microbial agent are that Y17 strains are colonized on the surface and pore channels of biochar, TBBPA in water is used as a carbon source, air and dissolved oxygen are used as oxygen sources, biochar provides the strains a growth microenvironment for degrading TBBPA in water, the strains are subjected to aerobic growth in water, and bio-enhanced degradation of TBBPA in water is performed by continuously degradation reaction. The removal method and the microbial strain as well as the microbial agent are high in degradation efficiency, environmental-friendly and low in cost, and can meet requirements on large-range promotion and application.

The present invention relates to Lactobacillus plantarum NK3 and Bifidobacterium longum NK49, which are novel lactic acid bacteria and, more particularly, to a composition comprising novel lactic acid bacteria useful for prevention and treatment of inflammatory diseases.

Bifidobacterium longum strains and cell wall fractions isolated from Bifidobacterium longum strains are useful in the prophylaxis or treatment of a respiratory viral infection in a subject. They are also useful in the prophylaxis of a secondary bacterial infection associated with a respiratory viral infection in a subject, especially a subject who is susceptible to respiratory infections.

Provided are a lysine decarboxylase immobilized cell and preparation method thereof.

The invention provides a bacterial composition which comprises from 10.sup.4 to 10.sup.12 cfu/g of Pediococcus pentosaceus cells which have the ability to induce the production of interleukin-10 to reduce inflammation in the intestinal tract among other features. Thus, the bacterial composition is useful in the amelioration of excessive crying in infants. Particularly, Pediococcus pentosaceus cells are from the strain deposited as CECT 8330. The bacterial composition can be in the form of a food supplement, a medicament, an infant formula, an edible product and a food product. Particularly, the composition is in the form of an infant food supplement in the form of oily suspension.

A method for inoculating a plant with a nitrogen-fixing bacteria such as Gluconacetobacter diazotrophicus, said method comprising administering the nitrogen-fixing bacteria to a wound of a growing plant, for example to recently cut grass. Inoculation in this manner leads to enhanced growth characteristics including increased greenness of grass. Novel compositions suitable for use in the method are also described and claimed, together with kits for producing these.

The present invention relates to a composition comprising a biologically pure culture of a fungicidal Paenibacillus sp. strain comprising a variant fusaricidin synthetase lacking a functional adenylation domain in the third module. The present invention also provides a composition comprising a biologically pure culture of a fungicidal Paenibacillus sp. strain or a cell-free extract thereof comprising at least one Paeniserine and at least one Paeniprolixin. Also provided are isolated compounds and methods of treating a plant to control a plant disease with the disclosed compositions and compounds.

The present invention provides a Lactococcus lactis subspecies lactis isolate WFLU-12 with the accession number o KCTC 13180BP, and a use thereof.

Provided are a transaminase mutant and an application thereof. Compared with an amino acid sequence shown in SEQ ID NO:1, an amino acid sequence of the transaminase mutant includes at least one of the following mutation sites: L166, K149, K146, A168, H73, F133, H82, E24, V194, T294, A295, G235 and F236. The mutant of the present invention has the improved catalytic activity for a transammonization reaction of ketone substrates, and is suitable for industrial production of chiral amines.
