Der Fachbereich Biologie verleiht den Doktorgrad als Anerkennung hervorragender wissenschaftlicher Leistungen und außergewöhnlicher Verdienste auf dem Gebiet der Biologie auch ehrenhalber (Ehrenpromotion - doctor honoris causa, h.c.).
Folgenden Wissenschaftlern ist diese Ehrung bislang zuteil geworden:
Kurylowicz, Wlodzimierz, Prof. Dr. Drs. h.c. (26.09.1910 - 21.02.1991)
Professor Włodzimierz is remembered as one of pioneers of the antibiotic  era.  He was born September 26, 1910 in Lvov. He received his MD from  the Jan Kazimierz University in Lvov. Following posts as an Associate  Professor of Microbiology at Lvov and as a research bacteriologist at  the National Institute of Hygiene in Warsaw he became a Professor of  Microbiology at that Institute. He was Director of the Institute from  1964 to 1980. More than 270 of this works regarded such topics as:  antibiotic biogenesis and biosynthesis, numerical taxonomy of Streptomyces spp.,  evaluation of BCG and microbial fine structure. Prof. W. Kuryłowicz was  a recipient of the National Prize Award for scientific guidance in  construction of the first antibiotic industry in Poland, and the  National Prize Award for the co-authorship of the monograph "Antibiotics  - Origin, Nature and Properties". He was also recipient of Doctorates  honoris causa of: Nicolas Copernicus Medical University in Poland;  University of Oslo; University of Lille; Medical University of Debrecen,  Hungary; University of Liège, Belgium; Federal University of  Pernambuco, Recife, Brazil; University of Quèbec, Canada; University of  Münster, Germany.
Preer Jr., John Randolph, Dr.; Distinguished Professor Emeritus, Indiana University, Bloomington, Indiana, USA
Prof. Peer's graduate work involved an analysis of the killer character in Paramecium,  a trait appearing to show a cytoplasmic form of inheritance that seemed  to challenge accepted ideas about genetics.  He worked on this problem  for the next 30 years, ultimately showing that the killer trait was due  to unusual bacterial endosymbionts that lived in the cytoplasm of Paramecium.   In 1985 he, his wife and life-long lab partner Bertie (Brandau) Preer,  and their associates Bertina Rudman and Audrey Barnett found that the  genetic code, universal for all previously described nuclear genes, was  unexcpectedly different in Paramecium. Awards: 1976 elected to  the National Academy of Sciences; 1976 Guggenheim Fellow, 1993 Honorary  doctorate in Mathematics and Natural Sciences, Wesfälische  Wilhelms-Universität Münster, Germany, 1998 Bloomington Distinguished  Faculty Research Lecturer, 2011 awarded President\'s Medal by IU  President McRobbie 
Demain, Arnold L., Dr.; Professor für Industrielle  Mikrobiologie, Massachusetts Institute of Technology (MIT), Cambridge,  Massachusetts, USA
Arnold L. Demain (born 27 April 1927) is an American microbiologist.  During his 60-year career, he has gained a renowned reputation in the  field of industrial microbiology. He was formerly the Professor of  Industrial Microbiology in the Biology Department at MIT and Founder and  Head of Department of Fermentation Microbiology at Merck & Co.  He  has been described as “one of the world’s leading industrial  microbiologists” and as “a scientist constantly in the forefront of  industrial microbiology and biotechnology.” He has been “a pioneer in  research on the elucidation and regulation of the biosynthetic pathways  leading to the penicillins and cephalosporins” and “has been  instrumental in the development of the beta-lactam industry. ” One  feature of Demain's work, according to Microbiology Australia, has been  his “ability to undertake fundamental research on systems with clear  industrial applications, recognising that biodiscovery is the start of  the road that includes strain improvement to achieve levels of product  synthesis that warrant further investment to take products into the  marketplace.”
