1. Production of functional microbial materials
Functional microbial materials in Examples 1 and 2 were produced by the methods described below.
[0041]
(Example 1)
For a fermentation raw material, a marine product-derived fermentation product was used which had been obtained by fermentation of a marine product ที่รวมถึง, as a plant-derived raw material, about 50% by weight of barley bran, about 20% by weight of, and about 10% by weight of rice bran, and further as an animal-derived raw material, about 20% by weight of crustaceans, such as shrimps and crabs, bottom fishes, and others caught by bottom trawling. The resulting marine product-derived fermentation product contained a population of microorganisms of ตั้งแต่ประมาณ 108 cells/g ถึงประมาณ 109 cells/g, which was composed of about 70% ถึงประมาณ 90% by weight of the microorganisms
ที่ระบุด้วย the หมายเลขการฝาก PTA-1773 and about 30% ถึงประมาณ 10% by weight of the microorganisms ที่ระบุด้วย the หมายเลขการฝาก NITE BP-1051.
[0042]
The plant-derived raw material and the animal-derived raw material were mixed and well stirred, and then subjected to single-stage fermentation at 40°C for 14 hours,
followed by drying to obtain a functional culture feed according to the การประดิษฐ์นี้. The resulting วัสดุเฉพาะทาง contained a population of microorganisms of from
about 108 cells/g ถึงประมาณ 109 cells/g, which was composed of about 90% ถึงประมาณ 99% by weight of the microorganisms ที่ระบุด้วย the หมายเลขการฝาก PTA-1773 and about 10% ถึงประมาณ 1% by weight of the microorganisms ที่ระบุด้วย the หมายเลขการฝาก NITE BP-1051.
[0043]
(Example 2)
For a fermentation raw material, a marine product was used which included, as a plant-derived raw material, about 20% by weight of a waste mushroom bed, and further as an animal-derived raw material, about 30% by weight of crustaceans, such as shrimps and crabs, bottom fishes, and others caught by bottom trawling. The waste mushroom bed contained a population of microorganisms of ตั้งแต่ประมาณ 108 cells/g ถึงประมาณ 109 cells/g, which was composed of about 70% ถึงประมาณ 90% by weight of the
microorganisms ที่ระบุด้วย the หมายเลขการฝาก PTA-1773 and about 30% ถึงประมาณ 10% by weight of the microorganisms ที่ระบุด้วย the หมายเลขการฝาก NITE
BP-1051.
[0044]
The plant-derived raw material and the animal-derived raw material were mixed and well stirred, and then subjected to two-stage fermentation. The fermentation
conditions in the first stage were 50°C to 60°C and 4 hours to 5 hours, while the
fermentation conditions in the second stage were 30°C to 40°C and 6 hours to 8 hours. After the second stage fermentation, the fermentation raw material that had gone through the fermentation process was dried to obtain a functional microbial material according to the การประดิษฐ์นี้. The resulting functional microbial material contained a
population of microorganisms of ตั้งแต่ประมาณ 108 cells/g ถึงประมาณ 109 cells/g, which was composed of about 70% ถึงประมาณ 90% by weight of the microorganisms ที่ระบุด้วย the หมายเลขการฝาก PTA-1773 and about 30% ถึงประมาณ 10% by weight of the
microorganisms ที่ระบุด้วย the หมายเลขการฝาก NITE BP-1051.

2. Activity for degradation of organic substances in soil and water environments with high salt concentration and high alkalinity
The populations of microorganisms ที่ระบุเป็น BP-1051 and as
เชื้อปลูกเธอร์โมไฟล์ MIROKU M2K were cultured, for example, in a heart infusion medium with a salt concentration of 10%, to select bacteria สปีชีส์ having an ability to degrade organic substances.
[0046]
Strain IP-9, which is contained in the population of microorganisms ที่ระบุเป็น BP-1051, is a สปีชีส์ closely related to the standard strain Virgibacillus pantothenticus, which produces ectoine, a component resistant to salt. Ectoine is known as a moisturizer. Actually, strain IP-9 was found to have an ability to degrade organic substances even at salt concentrations of 10% or higher. In addition, strain IP-9 is capable of co-culture with a สปีชีส์ closely related to Oceanobacillus profundus which is contained in the flora of bacteria of multiple สปีชีส์. This สปีชีส์ Oceanobacillus profundus is also known to have an ability to degrade organic substances at high salt and alkali concentrations; in fact, a สปีชีส์ closely related to Oceanobacillus profundus was found as a สปีชีส์ that was contained in the population of microorganisms ที่ระบุเป็น เชื้อปลูกเธอร์โมไฟล์ MIROKU M2K. At present, it has not become possible to perform persistent culturing of these bacteria สปีชีส์ as an isolated strain. In any case, it can be said that functions of these bacteria สปีชีส์ contribute to the cleanup of soil and water environments with high salt concentration and high strong alkali concentration. [0047]
