Rainer Borriss (born 30 April 1945) is a German microbiologist and professor emeritus at Humboldt University of Berlin. He is known for his work on Bacillus enzymes, Bacillus subtilis genome sequencing project, and for establishing Bacillus velezensis FZB42 as a model Gram-positive plant-beneficial bacterium. He held the chair for Bacterial Genetics at Humboldt University from 1992 to 2010 and co-founded the biotechnology company ABiTEP GmbH in 2005.[1]
As of April 2026, Borriss has an h-index of 74 and more than 23,000 citations according to Google Scholar.[2]
Borriss was born on 30 April 1945 in Prerow, Mecklenburg, Germany. He studied biology at Martin Luther University Halle-Wittenberg from 1964 to 1971, specialising in bacterial physiology. His early scientific development was influenced by botanist Kurt Mothes and microbiologist Erich Ohmann.[3]
He received his Diploma in Biology in 1971 and his doctorate (Dr. rer. nat.) in 1972. He completed his habilitation in 1979 and was awarded the facultas docendi at Humboldt University Berlin in 1987.[4]
Career
From 1971 to 1981, Borriss led microbiological laboratories at PROWIKO in Schönebeck/Elbe. During this period, microbial β-glucanase was developed as a substitute for malt in East German brewing.[5][6]
From 1981 to 1989, Borriss worked at the Zentralinstitut für Genetik und Kulturpflanzenforschung in Gatersleben.[7] He joined Humboldt University of Berlin in 1989 and was appointed Professor of Bacterial Genetics in 1992, serving until 2010. He was deputy director of the Institute of Biology from 2000 to 2001. Since 2010, he has held the title of professor emeritus at Humboldt University.[8]
Research
β-Glucanase enzymology
Borriss's early research focused on bacterial β-glucanases. In collaboration with Jürgen Hofemeister, he cloned and sequenced Bacillus β-glucanase genes.[9] At the Carlsberg Research Laboratory, he contributed to the development of thermostable hybrid β-glucanases.[10] Structural studies with Udo Heinemann led to the characterisation of enzyme structures including GluXyn-1.[11]
Bacillus subtilis genome project
Borriss participated in the international sequencing of the Bacillus subtilis genome.[12] His group contributed a chromosomal region involved in purine metabolism.[13] He later co-authored a review on genome annotation refinement.[14]
Plant growth promotion and biocontrol
From the 2000s, Borriss focused on plant growth-promoting bacteria. His group sequenced the genome of Bacillus amyloliquefaciens FZB42.[15] He identified gene clusters responsible for antimicrobial metabolites including lipopeptides, polyketides, and bacilysin.[16] His research also demonstrated the role of indole-3-acetic acid (IAA) in plant growth promotion.[17] In 2017, he contributed to taxonomic clarification within the Bacillus subtilis species complex.[18]
