Short-stemmed wood clinker cultivation is a new technology for Ganoderma lucidum cultivation which has developed rapidly in recent years. The average dry weight per cu m of wood is over 20 kilograms, and the high yield can reach 30 kilograms or more, which is 20% more than conventional cultivation method. The texture of Ganoderma lucidum is strong and glossy, and the acid content is higher than that of bag cultivation. More than 90% of the products meet the export requirements.
1. During the cultivation season, Ganoderma lucidum is a medium-high temperature type fungus, and its yield is related to the species, cultivation time, and cultivation techniques of the segment wood. The time of inoculation can be arranged from late October to December, or from early February to early March. Budding can receive 2-3 batches of fruit bodies. Inoculated before the mid-December period, in the second year of March, the trees can be planted in the second year. The output of the year accounts for more than 70% of the total output. In the first month of February, the quarantine was buried in April and the total output was 55%.
2. Raw materials 1 Broad-leaved tree species are suitable for cultivating Ganoderma lucidum, but hard-leaved hardwood trees have high yields and good quality. Such as: rice bran, eucalyptus, eucalyptus, etc., if the use of relatively loose material cultivation, the output decreased significantly in the second year. The trees with diameters between 8-20 cm were used. The cutting time was scheduled to be 3-5 weeks before inoculation, and the cuts and shavings were carried out about 1 week before inoculation. The water content was suitable for 38%-45%. 2Cultivated materials are mixed wood chips as the main raw material, and appropriate amount of auxiliary materials such as wheat bran and gypsum powder are added; plastic bags are made of low-pressure polyethylene material with a thickness of 0.45-0.6 cm, and the bag mouth diameter is 14, 15 and 20 cm. 45-55 cm long.
3. Production process Raw material preparation (log felling, cutting section) → Bagging → Zhakou → Sterilization → Inoculation → Hyphae culture → Laying on the soil → Out of the Chiba management → Ganoderma lucidum harvesting.
(1) Bagging The logs are cut into 30-cm long sections of wood, bagged, sectioned with wooden bottoms, and the wood chips are placed on the surface to sew the mouth. The sterilization is carried out at 100°C for 12-14 hours under atmospheric pressure.
(2) Inoculation The bagged section wood after sterilization is moved into the inoculation room (or inoculation box) for cooling, strictly inoculated according to aseptic operations, and the general amount of the wood used for each cubic meter of wood is 90-130 bottles, and the inoculation amount can be accelerated. Mycelium colonization reduces pollution rates.
(3) Mycelial culture culture room is disinfected before putting into the section wood bags. The inoculated section wood bags are piled up in the shape of “wellâ€. The indoor temperature is shaded at 20°C-25°C, and the cultivation room is after 1 week. Ventilation is performed once a day at noon, and ventilation is gradually increased with the extension of germination time. After about 60-70 days or more, the mycelium matured, and the soil was cultured in the ground.
(4) Go to bed and choose lee, sunny, well ventilated, convenient drainage site to build a shed, before the bacteria into the shade, remove weeds, pests, etc., the sun exposure after a few days to do 畦, 畦 width 100-120 cm, 20 cm deep, leaving a walkway, trampoline disinfestation, ant medicine, choose the temperature of 16 °C -22 °C sunny bagging buried wood.
(5) After the bacterium is managed, the mash bed is always wet, the shed temperature is controlled at 26°C-30°C, and the buds are unearthed within 15-20 days. Maintaining relative humidity at 85%-90%, when the ventilation, temperature, humidity, and light conditions are all suitable, the cap is differentiated. Therefore, the focus of the management of Shiba is the adjustment of the three elements of moisture, ventilation, and temperature.
(6) Harvest When the yellow-white growth circle disappears on the edge of the cap, the color of the cap increases, the cap gradually thickens, and a large number of red-brown spores can be released, and the water spray is stopped before harvesting.
Ibrutinib is a small molecule drug that binds permanently to a protein, Bruton's tyrosine kinase (BTK) that is important in B cells; the drug is used to treat B cell cancers like mantle cell lymphoma, chronic lymphocytic leukemia, and Waldenstrom's macroglobulinemia, a form of non-Hodgkin's lymphoma.
Ibrutinib is used to treat chronic lymphocytic leukemia, Waldenstrom's macroglobulinemia, and as a second-line treatment for mantle cell lymphoma, and marginal zone lymphoma.
We produce a series of complete intermediates for Ibrutinib, intermediate I (CAS No. 330786-24-8) and intermediate II (CAS No. 143900-44-1) etc.
All of our products are with stable production and strict quality control, making sure your experience with Sunshine Biotech is always enriching, satisfying and fulfilling.
