  • Patent number: 4818268
    Abstract: An osmoprotectant particle for use in enhancing fungus growth and particularly for use with edible mushrooms. The osmoprotectant particle includes a carrier particle, either a protein or a neutral material and a plurality of osmoprotectant microdroplets containing water soluble phosphoglyceride such as hydroxy lecithin and betaine or choline which are attached to a plurality of recesses formed about the carrier particle. Denaturation of the protein and/or control of a surface-to-volume ratio restricts access to the microdroplets such that only mushroom mycelia occuring in the later flushes will be able to utilize the phospholipid droplets. A method is provided for producing the osmoprotectant particles utilizing either the protein carrier particle or the neutral carrier particle.

  • Patent number: 4804402
    Abstract: A method and plant are provided for sterilizing waste sewage sludge with methyl bromide vapor, to produce a natural fertilizing material. The moisture content of the sludge is reduced to a level where the vapor permeability of the sludge is sufficiently high to reduce the contact period of the methyl bromide vapor with the sludge to an economically viable level. The methyl bromide is provided at a dose of at least 50 g/m.sup.3 to the top of a bed of sewage sludge having a moisture content of less than 35% and about 1 meter thick and allowed to permeate the bed over a period of about 48 hours under the force of gravity, the bed of sewage sludge being covered during the entire treatment period with a cover which is impermeable to the methyl bromide vapor. Harmful pathogens and parasites such as Ascaris ova are effectively eliminated.

  • Patent number: 4795724
    Abstract: Silicon nitride sintered bodies are disclosed, which each consist essentially of Si, O, N, and at least two kinds of rare earth elements selected from Y, Er, Tm, Yb, and Lu the bodies comprising not less than 70% by weight of Si.sub.3 N.sub.4. The ratio of the molar amount of all the rare earth elements contained in the sintered body calculated as moles of Ln.sub.2 O.sub.3, Ln being a rare earth element selected from Y, Er. Tm, Yb and Lu divided by the molar amount of oxygen calculated as moles of SiO.sub.2 is within the range of from 0.4 to 1.3. The amount of oxygen calculated as moles of SiO.sub.2 is obtained by subtracting the amount of oxygen contained in all the Ln.sub.2 O.sub.3, all the rare earth elements contained in said sintered body being considered as molecules of Ln.sub.2 O.sub.3 from the amount of oxygen contained in the sintered body and converting the remaining amount of oxygen into moles of SiO.sub.2.

  • Patent number: 4793927
    Abstract: A method of treating sewage is disclosed. Sewage is mixed with an ammonia source, and the mixture is formed into a substantially impermeable mass. The substantially impermeable nature of the mixture increases the ammonia concentration therein and substantially completely destroys all viable parasites. When the impermeable mass is formed by addition of cement and silicate, a strongly alkaline environment is created that kills bacteria and viruses. The resulting end product is a friable mass that is substantially free of pathogens and suitable for unrestricted reuse.
