5 results about "Irpex lacteus" patented technology

The preparation method comprises the following steps: mixing a termite palatable cellulose material, wheat bran, gypsum, cane sugar and water to prepare a culture material, packaging and sterilizing the culture material, inoculating the Irpex lacteus, culturing until hyphae cover all the culture material, and carrying out freeze-drying to obtain the Irpex lacteus living fungus termite bait. The hypha living body state is kept for trapping odontotermes formosanus to eat. Experiments of three indoor devices show that the food calling effect of the Irpex lacteus bait block on odontotermes formosanus is obviously superior to that of a sterile culture material contrast bait block. Field tests show that the eating efficiency of the Irpex lacteus living fungus bait is obviously superior to that of natural plant bait circulating in the current market. Meanwhile, breathable tubular and bag-shaped packaging is convenient to store and carry, and hyphae can survive for a long time. The Irpex lacteus living fungus bait is good in termite trapping effect, high in eating speed, not prone to being polluted by infectious microbes and suitable for monitoring, trapping and killing odontotermes formosanus on dams and gardens.

The invention discloses Irpex lacteus YYY-16, and the preservation number of the Irpex lacteus YYY-16 is GDMCC No: 67140. The invention further discloses a terpenoid and a preparation method thereof. The terpenoid has a structure shown in a formula I or a formula II. The invention further discloses application of the terpenoid in preparing tobacco pathogenic bacterium resisting drugs.

The invention provides Irpex lacteus S351, which is preserved in China General Microbiological Culture Collection Center (CGMCC), and the preservation number of the Irpex lacteus S351 is CGMCC No.42285. The Irpex lacteus S351 is named as Irpex lacteus S351. According to the Irpex lacteus S351, waste orange peel capsule dressing can be used as a main substrate for mycelium growth, the surface of the obtained mycelium is pure white, the structure is compact, the Irpex lacteus S351 can be used for preparing degradable and environment-friendly packaging materials, and the prepared packaging materials are excellent in buffering performance.

The application discloses a reference gene of Irpex lacteus, primers and application thereof. The reference gene comprises ubiquitin conjugating enzyme 1, autophagy protein Atg8, ubiquitin conjugating enzyme 2, calmodulin-dependent phosphatase and fungal protein kinase gene. The five reference genes disclosed in the application are suitable for expression level research of different expression level genes. The reference gene provided by the application has stable expression in different development periods and different culture conditions, and the reference primers have high specificity, stable amplification and amplification efficiency close to 100%. In addition, according to the expression level of a target gene, a suitable reference gene can be selected from the five reference genes for expression level research. The application provides new candidate reference genes which are more stable and more extensive than common reference genes such as gapdh for gene expression research of Irpex lacteus.

The present application relates to the technical field of fermentation, in particular to irpex lacteus and its application in the conversion of rare ginsenosides. The present application discovers and cultivates a wild irpex lacteus which can convert rare ginsenosides in panax notoginseng, further optimizes the irpex lacteus-panax notoginseng bidirectional solid fermentation process through experiments, and confirms that the process can efficiently convert common ginsenosides in panax notoginseng into rare ginsenosides; through pharmacodynamic evaluation, it is further shown that fermented panax notoginseng can significantly improve the pathological state of lupus nephritis model mice through multiple pathways such as immune regulation, inflammation inhibition and anti-kidney fibrosis, and its overall curative effect is better than that of panax notoginseng. The present application not only provides a new technical path for the deep development and value improvement of panax notoginseng, but also provides a potential candidate drug for the treatment of lupus nephritis, and embodies the wisdom of traditional Chinese medicine processing "synergistic and detoxification".
