Preparation method for blue-green algae single-cell protein feed
ActiveCN103749957ARealize feedPromote proliferationAnimal feeding stuffSingle-cell proteinBlue green algae
The invention provides a preparation method for a blue-green algae single-cell protein feed. According to the preparation method, aspergillus niger with the preservation number of CGMCC (China General Microbiological Culture Collection Center) No.8640 is used for carrying out solid-state fermentation on blue-green algae. The preparation method comprises the specific steps: (1) dehydrating the blue-green algae and carrying out filter pressing to prepare a blue-green algae dehydrated filtering block; (2) inoculating aspergillus niger liquid into a solid-state culture medium and culturing to obtain solid-state aspergillus niger; (3) adding the solid-state aspergillus niger into the blue-green algae dehydrated filtering block and mixing and fermenting to obtain a blue-green algae fermentation product; (4) drying the blue-green algae fermentation product by hot air, and crushing and sieving to obtain the blue-green algae single-cell protein feed. According to the preparation method for the blue-green algae single-cell protein feed, waste resources are utilized, the dehydration is energy-saving and the environmental pollution is not caused; the detoxification of micro-capsule blue-green algae toxin and the synchronous production of the single-cell protein feed are realized.

Method for producing exo-inulinase by solid-state fermentation of Streptomyces griseoplanus S501
ActiveCN104611311BHigh activityOvercome the disadvantage of high costMicroorganism based processesGlycosylasesFreeze-dryingStreptomyces griseoplanus
The invention provides a method of producing exoinulinase with utilization of solid state fermentation of streptomyces grisepoplanus S501 and belongs to the technical field of microorganisms. The method comprises the following steps: preparing a bacterial suspension by freeze-dried powder of a strain S501 and aseptic water on a selective medium, culturing for 3-5d at the temperature of 28 DEG C, scraping spores, putting the spores into the aseptic water, diluting until the concentration of a spore suspension is 106cfu / mL, inoculating to a solid state culture medium, and carrying out static culture for 3-6d at the temperature of 28 DEG C; and after fermentation, adding deionized water, carrying out oscillating extraction for 1h, filtering, carrying out centrifugation on a filtrate for 20 minutes at the temperature of 4 DEG C and the rotational speed of 8000rpm / min to obtain a supernatant containing the exoinulinase, and treating the supernatant by virtue of the conventional freeze-drying method to prepare an inulinase preparation. According to the method provided by the invention, with wheat bran as a solid fermentation matrix and garlic husk powder which is cheap and easily acquired as a carbon source, the strain S501 is induced to produce the exoinulinase, the enzyme activity of the exoinulinase reaches up to 209.63 + / - 0.96U / g, and the defects of high cost, time and labor consumption in a liquid state fermentation method and non suitability in industrial production in the prior art with inulin as a carbon source are overcome.
