    Opis:
    Cordyceps militaris, a precious medical mushroom, has attracted wide attention in industrial fields. Currently, the degeneration phenomenon of C. militaris commercial strains is amongst the major challenges for cultivation at the industrial scale. The screening for superior strains with high yield and medicinal value is considered a realistic approach to overcome degeneration problems. In the present study, the mycelial growth, primordia formation, yield performance, and cordycepin content of five strains (DT1, DT2, DT3, DT4, and DT5) under artificial cultivation conditions were investigated. All strains showed mycelial growth on SDAY and liquid medium. The strains were successfully cultivated in brown rice medium and required 18 (strain DT3) to 25 days (strain DT5) to form primordia. Additionally, morphological characteristics of fruiting bodies varied among the strains. Strains DT4 and DT3 exhibited the highest fruiting body length with 74.23 ± 5.13 mm and 72.63 ± 2.62 mm, respectively whereas the highest diameter was recorded for strains DT1 (4.05 ± 0.18 mm) and DT2 (3.63 ± 0.12 mm). Of note, among the investigated strains, strain DT3 exhibited the highest biological efficiency (8.95 ± 0.07%) and cordycepin content (1.68 mg/g). Therefore, strain DT3 could be selected as a potential strain for commercial cultivation.

    Opis:
    Purpose: Determine the state of stress-strain, formation and development cracks, three-layer beam diagrams of load-compression stress, load-tension stress, load-vertical displacement relationships with a change in concrete grade. Design/methodology/approach: This paper presents the results of an ANSYS numerical simulation analysis involving stress-strain state and cracking of the steel fiber concrete layers of three-layer reinforced concrete beams with the upper and lower layers. With a cross-section of 150x300 mm, a total span of 2200 mm and an effective length of 2000 mm, the middle is a normal concrete layer. Under two-point loads, all the beam samples were tested. The research simulated three-layer concrete beams in different layers of beams with a change in concrete grade, and compared with and without the use of steel fibers in layers of concrete beams, including the nonlinearity of the material considered. Findings: A diagram of the formation and development of cracks in three-layer concrete beams has been constructed by the study results, determining the load at which the concrete beams begin to crack, the load at which the concrete beams are damaged. In the middle of three-layer steel fiber reinforced concrete beams, load-compression stress, loadtension stress, load-vertical displacement relationships are established. Study results show that these three-layer concrete beams appear to crack earlier than in other cases in cases 2 and 3, but the beam bearing capacity is damaged at 67 kN, the earliest in case 3. And case 6 at 116 kN is the latest. The effects of case 1 and case 3 are small compared with and without the use of steel fibers in cases, while the effects of case 5 and case 6 are very high. Research limitations/implications: The research focuses only on the change of concrete grade in the layers, but the input parameters affecting three-layer steel fiber concrete beams have not been researched, such as the number of tensile steel bars, tensile steel bar diameter, steel fiber content in concrete, thickness variation in three-layer concrete beam layers, etc. Practical implications: Provides a result of experimental study and ANSYS numerical simulation in multi-layer steel fiber concrete beams. Originality/value: The analysis of multi-layered steel fiber concrete beams using experimental and simulation methods shows that other parameters influencing the beams will continue to analysis the working stages of three-layer beams.
