Basic Biotechnology

Ratledge C., Kristiansen B. (Eds.)-Basic Biotechnology-Cambridge University Press (2006)

Biotechnology is one of the major technologies of the twenty-first century. Its wide-ranging, multi-disciplinary activities include recombinant DNA techniques, cloning and the application of microbiology to the production of goods from bread to an Grundlegende, leicht verstandliche Einfuhrung in das Modelling der Fermentationskinetik mit praktischen Lernhilfen. Citric acid biotechnology is the subject of both industrial and academic interest. For a long time the production of citric acid was one of the driving forces in industrial biotechnology, lying in the interface between old and new technology. Now, not only is citric acid biotechnology of great industrial and economic importance, it is also used to illustrate biotechnological principles at undergraduate level.

Its wide-ranging, multi-disciplinary activities include recombinant DNA techniques, cloning and the application of microbiology and other cell culture technologies to the production of a wide range of goods from bread to antibiotics. It continues to revolutionise treatment of many diseases, and it is used to provide clean technologies and to deal with environmental problems. This new edition of Basic Biotechnology uniquely combines biology and bioprocessing topics to provide a complete overview of biotechnology.

Bjorn Kristiansen , Colin Ratledge Herausgeber. Biotechnology is one of the major technologies of the twenty-first century. Its wide-ranging, multi-disciplinary activities include recombinant DNA techniques, cloning and the application of microbiology to the production of goods from bread to antibiotics. In this new edition of the textbook Basic Biotechnology, biology and bioprocessing topics are uniquely combined to provide a complete overview of biotechnology. The fundamental principles that underpin all biotechnology are explained and a full range of examples are discussed to show how these principles are applied, from starting substrate to final product. A distinctive feature of this text are the discussions of the public perception of biotechnology and the business of biotechnology, which set the science in a broader context. This comprehensive textbook is essential reading for all students of biotechnology and applied microbiology, and for researchers in biotechnology industries.

Тело его обгорело и почернело. Упав, он устроил замыкание основного электропитания шифровалки. Но еще более страшной ей показалась другая фигура, прятавшаяся в тени, где-то в середине длинной лестницы. Ошибиться было невозможно.

Энсей Танкадо отдал кольцо, надеясь обнародовать ключ. И теперь - во что просто не верится - какой-то ни о чем не подозревающий канадский турист держит в своих руках ключ к самому мощному шифровальному алгоритму в истории. Сьюзан набрала полные легкие воздуха и задала неизбежный вопрос: - И где же теперь этот канадец. Стратмор нахмурился: - В этом вся проблема.

С гулко стучащим сердцем Беккер надавил на газ и исчез в темноте. ГЛАВА 84 Джабба вздохнул с облегчением, припаяв последний контакт. Выключив паяльник, он отложил в сторону фонарик и некоторое время отдыхал, лежа под большим стационарным компьютером. Затекшая шея причиняла ему сильную боль. Такая работа была непростой, особенно для человека его комплекции.

 - Он стал калекой из-за этих бомб. И он знал про них .

Дойдя до конца туннеля, Сьюзан уткнулась в круглую сейфовую дверь с надписью СЕКРЕТНО - огромными буквами. Вздохнув, она просунула руку в углубление с цифровым замком и ввела свой личный код из пяти цифр. Через несколько секунд двенадцатитонная стальная махина начала поворачиваться. Она попыталась собраться с мыслями, но они упрямо возвращали ее к. Дэвид Беккер.

Проехав еще полмили, Сьюзан подверглась той же процедуре перед столь же внушительной оградой, по которой был пропущен электрический ток. Давайте же, ребята… уже миллион раз вы меня проверяли. Когда она приблизилась к последнему контрольно-пропускному пункту, коренастый часовой с двумя сторожевыми псами на поводке и автоматом посмотрел на номерной знак ее машины и кивком разрешил следовать. Она проехала по Кэнин-роуд еще сотню метров и въехала на стоянку С, предназначенную для сотрудников.

GOV Гнев захлестнул ее, но она сдержалась и спокойно стерла сообщение. - Очень умно, Грег. - Там подают отличный карпаччо.  - Хейл улыбнулся.

Он понимал: выбраться из шифровалки ему удастся, только если он пустит в ход все навыки поведения в конфликтных ситуациях, которые приобрел на военной службе.
