Fusion proteins containing a targeting sequence, an exosporium protein, or an exosporium protein fragment that targets the fusion protein to the exosporium of a Bacillus cereus family member are provided. Recombinant Bacillus cereus family members expressing such fusion proteins are also provided. Genetically inactivated Bacillus cereus family members and recombinant Bacillus cereus family members that overexpress exosporium proteins are also provided. Seeds coated with the recombinant Bacillus cereus family members and methods for using the recombinant Bacillus cereus family members (e.g., for stimulating plant growth) are also provided. Various modifications of the recombinant Bacillus cereus family members that express the fusion proteins are further provided. Fusion proteins comprising a spore coat protein and a protein or peptide of interest, recombinant bacteria that express such fusion proteins, seeds coated with such recombinant bacteria, and methods for using such recombinant bacteria (e.g., for stimulating plant growth) are also provided.

The present disclosure relates to the use of a cpcR regulator gene, which directs the expression of promoters of genes encoding Cry proteins, for reducing the sporulation of a strain of Bacillus thuringiensis, new recombinant strains of Bacillus thuringiensis and uses thereof as biopesticide.

The present invention discloses a composition comprising heat inactivated spores and/or comprising heat inactivated vegetative cells of probiotic bacteria Bacillus coagulans, and a process for preparing the same. The invention also discloses a method of modulating immune function in mammals by activating macrophages, using a composition comprising Bacillus coagulans in the form of live or heat inactivated spore and/or vegetative cells.

A flow of air including a fungal spore is directed to a collection cartridge. The spore is trapped within the cartridge and positioned within a field of view of a camera sensor. A UV light is activated to illuminate the spore and a camera shutter is opened for a time period. The camera sensor collects light emitted from the spore during a first portion of the time period. After the first portion has elapsed, first and second bursts of white light originating from first and second positions, respectively, are directed towards the spore during a second portion of the time period. After the second portion of the time period has elapsed, the camera shutter is closed to generate an image. The image is analyzed to obtain a shape of the spore.

We found that bacterial spores could be pretreated or initially treated with a partial complement of germinants (i.e., less germinants than would cause germination) and, subsequently, could be treated with the remaining germinants to cause germination of the spores. In some instances, the pre-treated spores germinated more efficiently than bacterial spores to which the full complement of germinants was simultaneously added to the spores.

Provided are compositions and methods for making a diploid yeast having heterozygosity for at least one chromosome. The method includes mating haploid yeast having at least a first modified chromosome comprising a synthetic chromosome suitable for recombination-site-mediated evolution (as a SCRaMbLE-ready modification). The SCRaMbLE-ready modification includes introduced site-specific recombinase recognition sites that can be recognized by a recombinase. Yeast that have at least one SCRaMbLE-ready modification of a chromosome are mated with a haploid yeast devoid of the SCRaMbLE-ready modification to obtain diploid SCRaMbLE-ready yeast. Subsequent to mating the haploid SCRaMbLE-ready yeast to yeast devoid of the SCRaMbLE-ready modification the method includes using the recombinase to recombine the first modified chromosome to obtain heterozygous diploid yeast comprising at least one recombined (SCRaMbLEd) chromosome and a homologous non-SCRaMbLEd chromosome. The method further includes identifying heterozygous diploid yeast that comprise the at least one SCRaMbLEd chromosome that have a changed phenotype that is different from the phenotype of the diploid SCRaMbLE-ready yeast. Yeast made by the methods, compositions of matter made by the yeast, spores made by the yeast, and kits containing the yeast and/or their spores are included.

The present invention discloses A METHOD TO PRODUCE PROTEIN IN PENICILLIUM AMAGASAKIENSE'S SLEEPING SPORES BY TRANSFORMATION OF SSRNA. The method includes three steps of culture of Penicillium amagasakiense and collection of spores, pretreatment of Penicillium amagasakiense spores, and electroporation of Penicillium amagasakiense spores by using HDEN method. In the present invention, non-germinated spores are used as a starting material for introduction of exogenous molecules. The exogenous protein coding single stranded RNA is introduced into the resting spores of Penicillium amagasakiense by employing the HDEN electrotransformation technique to express protein. The method of this invention is simple and fast, the effect is excellent, and the transformation rate reaches more than 90%.
