Embodiment 1

[0027] (1) Rinsing of seaweed processing waste: Soak the seaweed processing waste in water, rinse with water to remove sand, and rinse repeatedly three to four times.

[0028] (2) Grinding of seaweed processing waste: processing the seaweed processing waste with a pulverizer for 3-5 minutes, and crushing to a particle size of 20-80 mesh.

[0029] (3) Putting the treated seaweed processing waste into a fermentation device and mixing it with water to make a suspension with a concentration of 10% (mass volume ratio).

[0030] (4) Preparation of high-temperature Saccharomyces cerevisiae seed liquid: first prepare a liquid seed medium. Peel the potatoes, take 100g and cut into pieces, boil for 15min, then filter with gauze, then add 10g of sucrose, stir and mix well, then add water to make 500ml, divide into triangle flasks, seal at 115°C, and sterilize for 30min. After sterilization, a ring of high-temperature Saccharomyces cerevisiae is picked up from the liquid seed medium with...

Embodiment 2

[0038] (1) Seaweed waste rinsing: soak the seaweed waste in water, and rinse with water three to four times.

[0039] (2) Grinding of the seaweed waste residue: the seaweed waste residue is crushed with a pulverizer for 3-5 minutes, and its particle size is crushed to a size of 20-80 mesh.

[0040] (3) Put the treated seaweed processing waste into the fermentation device and mix with water to make a suspension with a concentration of 5% (mass volume ratio).

[0041] (4) Preparation of high-temperature Saccharomyces cerevisiae seed liquid: first prepare a liquid seed medium. Peel the potatoes, take 100g and cut into pieces, boil for 15min, then filter with gauze, then add 10g of sucrose, stir and mix well, then add water to make 500ml, divide into triangle flasks, seal at 115°C, and sterilize for 30min. After sterilization, a ring of high-temperature Saccharomyces cerevisiae is picked up from the liquid seed medium with an inoculation loop, and the high-temperature Saccharomyc...

Embodiment 3

[0049] (1) Rinse kelp processing waste residue: add water to soak, and rinse with water three to four times.

[0050] (2) Pulverization: pulverize the kelp processing waste residue with a pulverizer for 3-5 minutes, and pulverize its particle size to a size of 20-80 mesh.

[0051] (3) Put the processed pulverized particles into a fermentation device and mix with water to make a suspension with a concentration of 2.5% (mass volume ratio).

[0052] (4) Preparation of high-temperature Saccharomyces cerevisiae seed liquid: first prepare a liquid seed medium. Peel the potatoes, take 100g and cut into pieces, boil for 15min, then filter with gauze, then add 10g of sucrose, stir and mix well, then add water to make 500ml, divide into triangle flasks, seal at 115°C, and sterilize for 30min. After sterilization, a ring of high-temperature Saccharomyces cerevisiae is picked up from the liquid seed medium with an inoculation loop, and the high-temperature Saccharomyces cerevisiae seed liq...

Abstract

The invention relates to a method for producing ethanol through synchronous fermentation of seaweed processing waste, which comprises the following steps of: rinsing, crushing and screening the seaweed processing waste, adding water to prepare suspension, regulating the system to have a proper pH value, and supplementing necessary nutritive salt; and controlling system temperature, adding a composite degradation enzyme solution, inoculating high temperature brewing yeast to synchronously perform sugar chain enzymolysis and ethanol fermentation of the seaweed processing waste efficiently in short time under the anaerobic condition. The method has the characteristics of simple equipment and method, quick operation, short treatment period, low production cost and the like.

Description

technical field [0001] The invention relates to the technical field of marine organisms, in particular to a method for producing ethanol by synchronous fermentation of seaweed processing waste. Background technique [0002] The depletion of fossil energy and the seriousness of environmental pollution have aroused widespread concern around the world, and the cleanliness and energy alternatives of bioethanol have been recognized by the world. The current bioethanol is mainly produced by using crops as raw materials, which greatly affects the food security of the world population. The emergence of the second-generation fuel ethanol will be the direction of future bio-ethanol development, and it will get rid of the embarrassing situation of competing with others for food and land. In our country or in the world, the second-generation biomass raw materials (crop straw, agricultural processing by-products, shrub energy forest cellulose) can be said to be cheap materials that can ...
