Mina Bizic is an
environmental microbiologist with particular interest in aquatic systems. She is mostly known for her work on organic matter particles and oxic methane production. She was named a fellow of the
Association for the Sciences of Limnology and Oceanography (ASLO) in 2022, and is serving on the ASLO board of directors where she is chairing the Early Career Committee.
Education and career
Bizic completed her Diploma studies in General Biology, and Hydroecology and Water Protection at the University of Belgrade from 1999 to 2005. Following her diploma, in 2005–2006, she engaged in transdisciplinary academic research in Ancient Jewish texts studies at the
European Institute for Jewish Studies in Sweden (PAIDEIA).[1] She later moved to Israel, where she worked for three years at the Kinneret Limnological Laboratory (KLL) of the Israel Oceanographic and Limnological Research[2] (IOLR).
During her investigations into
marine and lake snow, Bizic and her collaborators developed a novel experimental device, a flow-through rolling tank, which facilitates long-term experiments on marine and lake snow[5] while addressing biases inherent in closed systems, commonly referred to as the bottle effect.[6] Using this device, Bizic demonstrated that microbial degradation of marine snow takes longer than predicted using closed experimental systems. This finding implies that the
biological carbon pump may sequester more carbon than experimentally estimated.
In a subsequent study, Bizic and her colleagues conducted the first research utilizing molecular tools to focus on individual marine and lake snow particles rather than pooling thousands together. This groundbreaking study revealed that particles from the same source are colonized by different bacteria, in what appears to be a stochastic colonization process. Furthermore, the study highlighted that, at the early stages of colonization, bacterial succession is primarily driven by competition rather than a change in the quality of available organic matter.[7]
In parallel with her work on marine and lake snow, Bizic has delved into
aerobic methane production,[8] a phenomenon known as "The Methane Paradox".[9] This process is increasingly recognized as a significant source of the potent greenhouse gas
methane in aquatic systems. Bizic and her colleagues were the first to demonstrate the conversion of methylamines to methane under aerobic conditions.[10] This process was later comprehensively characterized by Wang and colleagues.[11] Subsequently, Bizic and her team revealed that
cyanobacteria, the most abundant photosynthetic organisms on Earth, emit methane as a byproduct of
photosynthesis.[12][13][14][15][16][17][18] The implications of this discovery were explored by Bizic in a subsequent opinion paper.[19]
Recognition and activities
In 2022, Bizic was elected to the Board of Directors of the
Association for the Sciences of Limnology and Oceanography (ASLO).[20] She currently serves as a member at large and chairs the Early Career committee of ASLO, organizing activities for the benefit of early career scientists such as the promotion of early creer scientist from historically excluded groups[21] as well as organizing webinars to improve the mental well-being of scientists.[22] Bizic's contributions to aquatic research and to ASLO were further acknowledged when she was named an ASLO fellow in 2022.[23]
Beyond her academic endeavors, Bizic is involved in the
Global Lake Ecological Observatory Network (GLEON), and as of 2024, serves as a member in their committee for inclusive collaboration.[24] Bizic has participated in interviews, events and panel discussions addressing the role of
women in science such as the Marthe Vogt podcast[25][26] and the
Soapbox Science.[27][28]
Personal life
Mina Bizic was born in
Belgrade, Serbia, and has lived in Sweden and Israel. In 2009, she relocated to Germany. She is the sibling of opera singer
David Bizic and is married to fellow scientist
Danny Ionescu, with whom she has two children.[25]
