The present invention has an object of providing a modified lipase having excellent stability and reactivity at a high temperature. Provided is a modified lipase with improved reactivity and/or stability at a high temperature, the modified lipase having an amino acid sequence including one or more amino acid substitutions which are selected from the group consisting of T130C-S153C, A249P, F259Y, S282P, S283Y and S300P in the amino acid sequence represented by SEQ ID NO: 1, or an amino acid sequence having 90% or more sequence identity therewith.

A recombinant bacterium for producing L-lysine, a construction method thereof, and a method for producing L-lysine by using the recombinant bacterium. The recombinant bacterium has increased expression and/or activity of asparaginase compared to a starting bacterium.

A microbial-based composition provides a co-cultured microorganism consortium in culture medium that includes one or more Acetobacter sp., Bacillus sp., Bifidobacterium sp., Enter ococus sp., Gluconacetobacter sp., Lactobacillus sp., Rhodopseudomonas sp., Saccharomyces sp., Pichia sp., and Trichoderma sp., as well as a carbon source and chlorine-free water. In some embodiments, the microbial-based composition is useful in the agricultural industry as a plant growth promoting and silage-enhancing agent. For plant growth promotion applications, the microbial-based composition may be applied to the foliar surface of a plant or to the plant growth medium, such as soil or hydroponic solution, surrounding the plant. In silage operations, the microbial-based composition may be applied to a cut plant product during one or more stages in the silage process.

Provided herein is a recombinant vector that comprises a promoter, a secretion tag gene of interest (GOI), and optionally a purification and/or a detection tag. The GOI comprises a polynucleotide sequence of SEQ ID NOs: 2-45 or a polynucleotide sequence with at least 90%, 95%, 98%, 99% or 99.9% identity with any one of SEQ ID NOs: 2-45. Also, disclosed are the sequences of polypeptides that result from expression of a GOI by a host expression system, and a method of producing cannabinoid compounds.

A novel isolated Pichia stipitis strain is provided. The strain is capable of fermenting at least a pentose sugar in the presence of one or more inhibitory substances to produce ethanol. A method of utilizing the strain to produce ethanol is also provided.

The present invention provides polynucleotide vectors for high expression of heterologous genes. Some vectors further comprise novel transposons and transposases that further improve expression. Further disclosed are vectors that can be used in a gene transfer system for stably introducing nucleic acids into the DNA of a cell. The gene transfer systems can be used in methods, for example, gene expression, bioprocessing, gene therapy, insertional mutagenesis, or gene discovery.

The present application relates to the field of enzyme engineering, especially relates to a pullulanase as well as preparation and use thereof. The pullulanase and coding gene thereof were obtained by random mutation by using the Error-prone PCR technique on the gene of wild-type pullulanase to obtain a mutant PLUM. The enzyme activity of the mutant PLUM was improved by 57.03% compared with the wild-type pullulanase PLUM.
