Hat noch jemand Prüfungsfragen von vergangenen Klausuren oder Tipps zur Prüfung? Wäre prima! Ich kann einfach nicht einschätzen, welche Reaktionswege jetzt wichtiger sind.:/

Sinngemäß die Prüfungsfragen vom 2.3.2015
1 Describe the Enzymes involved in Cellulose degradation
2 Microbial steps in biogas formation
3 Discuss the biotechnological relevant steps in the production of 2nd generation biofuels (er meinte man soll alle prozessschritte beschreiben, die was mit biotechnologie zu tun haben)
4 Describe the degradation of anthracene and bromoxynil
5 List five applications of enzymes for products of lignocellulosic material
6 Describe applications of bioremediation and the rationale for selecting the method of choice

Mal ein kleines update weil die letzten posts schon länger her sind.

Gruppe A 11.3.2019

1) Discuss advantages/disadvantages 1st and 2nd gen biofuels
2) Furan based polymer, production and uses
3) Describe enzymatic processes of pulp and paper industry
4) Biotechnologic processes for air cleaning
5) Which Biotechnologic processes can be used for Biodiesel production and side-stream usage
6) Describe enzymatic degradation processes of Lignin
7) List Photoautotrophic organisms + atleast one product each


also mir persönlich etwas unangenehme prüfung, weil sie fragen sehr wage gestellt sind und ich nicht klar ist was er jetzt hören will bzw. manche Fragen sind mir ein Rätsel wie man die mit den Folien alleine lösen soll (zB 5.)

Prüfung vom 16.12.2019:

.) Name three polymers of microbial origin and discuss their structure and use

.) Give an overview on open and closed micro algae cultivation methods regarding their advantages and disadvantages

.) Describe two bio-remediation methods for metal contamination in soil

.) Discuss the advantages and disadvantages of different types of bio reactors for bio gas production

.) List different applications of enzymes in the pulp and paper industry

.) Describe the structure and degradation of cellulose and hemi-cellulose and the according enzymes

.) Differences, advantages and disadvantages of 1st and 2nd generation bio fuels


In general, the questions are very superficial and the time is very tight, so it is not possible to answer the questions deeply.
