Problems solved by technology

However, with the continuous increase in the number and variety of chemical products produced by seaweed, the amount of waste formed after the chemical process of seaweed is also increasing, and in some areas, these residues are littered or lack effective treatment methods and utilization. Therefore, the treatment and comprehensive utilization of seaweed chemical waste is an urgent issue in the field of chemical processing of marine resources.

Abstract

The invention discloses a method for producing alcohol and feed by alga chemical waste, i.e. using the cellulose-containing waste residues as raw materials formed in the course of producing sodium alginate, mannitol, I or trehalose glue products in the alga chemical industry, making enzymatic hydrolysis by cellulase and anaerobic fermentation by brewing yeast or double fermentation by cellulase producing bacteria and brewing yeast, then making solid-liquid separation and obtaining alcohol and feed. And the invention provides economic, environmental protection and effective industrial technique for waste residues and waste liquid in the alga chemical industry, able to turn waste into wealth and provide important technical support for full and high value utilization of alga resources and development of alga circulating economy.

Description

Technical field [0001] The invention belongs to the technical field of marine resource biology, and in particular relates to a method for producing ethanol and protein feeds by bioconversion of enzymes and microorganisms using seaweed chemical waste. Background technique [0002] Seaweed mainly refers to brown algae (kelp, kelp, mozuku, spore leaf algae, wakame, hijiki, sargassum, rope algae, laver, etc.) that are naturally or artificially cultivated in the ocean. There are artificial breeding bases of different scales in Shandong, Fujian and Zhejiang. There are a large number of wild macroalgae and other abundant algae resources along the coasts of South and North America. [0003] Seaweed is an important chemical raw material that can be used to produce chemical products such as sodium alginate, mannitol, iodine, and fucoidan. After the large-scale promotion of kelp and other brown algae breeding technologies in my country in the 1950s, a seaweed industrial system was establish...
