Description
Известен способ производства питательной среды дл микроорганизмов путем двухстадиГпгой тепловой обработки зеленых водорослей с применением прн ь/том химических реактивов , неоднократного вакуумного высушивани Н фильтровани .A known method for the production of a nutrient medium for microorganisms by two-stage heat treatment of green algae using the primer / volume of chemical reagents, repeated vacuum drying of H filtering.
Дл упронюни процесса и обеспечени максимального извлечени из водорослей легкоусво ел1ых дл микроорганизмов питательных ве цеств, первую стадию нроцесса ведут нри более низких температурах, чем вторую.In order to maximize the process and ensure maximum extraction of nutrients from algae that are easy for microorganisms, the first stage of the process is conducted at lower temperatures than the second.
Так, желательно на первой стадии процесса поддерживать температуру 48° С в течение 48 час, на второй 160-180° С в течение 1-2,5 час.Thus, it is desirable to keep the temperature 48 ° C for 48 hours at the first stage of the process, 160-180 ° C for the second stage for 1-2.5 hours.
Снособ заключаетс в следующем.The way is as follows.
Термическую обработку водорослей провод т в две стадни.Heat treatment of algae is carried out in two herds.
На первой стадии (автолиз) температура 48° С, продолжительность обработки 48 час, на второй стадии (гидролиз) температура 160-180° С, ирпдолжительность обработки 1-2,5 час. При нроведенит низкотемиературной обработки водорослей происходит под действием ферментов клетки расщепле11ие сложных белковых соединений до аминокислот и других легкоусво емых микроорганизмами соединений. При этом до 50% азотсодерл ащих веществ биомассы водорослей переходит в растворимое состо ние. Во врем высокотемпературной обработки (втора стади ) из оставшегос осадка происходит извлечение азотсодержащих веществ и углеводов .In the first stage (autolysis), the temperature is 48 ° C, the duration of treatment is 48 hours, in the second stage (hydrolysis) the temperature is 160-180 ° C, and the treatment time is 1-2.5 hours. In the case of low-temperature treatment of algae, under the action of cell enzymes, cleavage of complex protein compounds to amino acids and other compounds easily digested by microorganisms occurs. At the same time, up to 50% of nitrogenous algae biomass of substances turns into a soluble state. During the high-temperature treatment (second stage), nitrogen-containing substances and carbohydrates are extracted from the remaining sludge.
Общее количество переведенных в раствор веществ биомассы зеленых водорослей (хлореллы ) составл ет в среднем 70-90% от исходного материала.The total amount of green algae (chlorella) biomass substances transferred to the solution averages 70-90% of the starting material.
Таким образом, предлагаемый способ обеспечивает гл)бо1а Й гидролиз как белковой, так и углеводной фракций исходной биомассы и не требует химических реактивов.Thus, the proposed method provides for the hydrolysis of both the protein and carbohydrate fractions of the initial biomass and does not require chemical reagents.
Предмет изобретени Subject invention
1.Снособ производетва пптательной среды дл микроорганизмов из зеленых водорос.лей путем двухетадийно тепловой обработки водорослей, отличающийс тем, что, с целью упрощени нроцесса и максимального извлечени из водорослей легкоусво емых дл микроорганизмов питательных веществ, первую стадию процесса ведут при более ццзких температурах , чем вторую.1. A method for producing a test medium for microorganisms from green algae by means of two-stage heat treatment of algae, characterized in that, in order to simplify the process and maximally extract nutrients that are readily available for microorganisms from algae, the second.
2.Спосои но п. i, отличающийс тем, что первую стадию процесса провод т иреимущественно при 48° С в течение 48 час, а вторую стадию при 160-180° С в течение 1-2,5 час.2. Claim i, characterized in that the first stage of the process is carried out mainly at 48 ° C for 48 hours and the second stage at 160-180 ° C for 1-2.5 hours.
