  • Patent number: 4565552
    Abstract: In the mesophile production of biogas, the temperature of the liquid used during anaerobic, methanogenic, fermentation is raised to the required temperature (about 35.degree. C.) by aerobically prefermenting solid substrate at substantially ambient temperature and of appropriate moisture content to raise its temperature to a temperature greater than that required for the anaerobic, methanogenic, fermentation. Thereafter flooding the fermenting solid substrate with the liquid at substantially ambient temperature to increase the temperature of the liquid by heat exchange, and then removing the liquid and storing it in a heat insulated environment to reduce the moisture content of the solid substrate to a suitable degree. The above steps of aerobic prefermenting and flooding are repeated until the liquid has reached the required temperature, and then leaving the liquid in situ to enable anaerobic methanogenic fermentation to take place.

  • Patent number: 4317670
    Abstract: The present invention relates to the environment protection and, more specifically, to microbiological processes for recultivation of industrial refuse heaps.The process of the present invention involves treatment of the heaps with fertilizers resulting from purification of production-communal waste waters, followed by treatment with a humic preparation containing a culture of the mold fungus Aspergillus niger. Then plowing of the ground is effected with a subsequent sowing with seeds of perennial plants. The heap surface sown with said seeds is inoculated with a bacterial preparation containing a culture of ammonifying and nitrifying bacteria.During the period of the plant sprouting and tillering inoculation is effected by means of a bacterial preparation containing a culture of azotobacter and phosphate-dissolving bacteria. All these bacteria are recovered from said refuse heaps, wherefore they are already adapted thereto.

  • Patent number: 4311510
    Abstract: A method for producing a fertilizer and decay promoting substance by subjecting grape marc to aerobic decay so that in a first phase, the sugar content is converted to alcohol and microbial fermentation produces organic acids. During the first phase, the alcohol and acids react to produce aromatic esters and a decay stabilized mass. In a second phase, the mass is rearranged to facilitate access of air and promote penetration of the mycelia of Humicola lanuginusa and thermophilic actinomycetes into the mass. In a third step, the mass is rearranged to effect microbial degradation of the mycelia and the mass is dried and the pip-containing fraction is separated. The thus obtained pips or seeds are infested with spores of the above-mentioned microorganisms and still contain their natural oil content and constitute an excellent high-grade fertilizer and aerobic decay promoting agent for the decay of vegetable and animal waste materials.

  • Patent number: 4302546
    Abstract: An airtight chamber insulated with an anti-corrosive coating allows the control of the heat and moisture content of organic wastes for rapid aerobic decomposition by naturally occurring thermal bacteria. Air is drawn into the chamber, over and through the organic waste and carbonaceous filler materials and is exhausted through an air scrubber. Agitation of the waste mixture is by means of two or more anti-corrosive coated stirrers on a rotating shaft; the rotation rate being two revolutions or less per minute to accelerate the biological decomposition process and 35 or more revolutions per minute to fluff and dry the material after the completion of the biological process. During the drying process the air direction is reversed by means of a blower and a controlled heating element to speed drying. Utilization of the blower and heating element also helps to initiate the biological decomposition activity in cold temperatures.
