Lactic acid production from corn cob
(Nacionalno društvo za procesnu tehniku i energetiku u poljoprivredi, Novi Sad, 2021)
Over the past decade, a growing interest in bio-based plastics, such as poly-lactic acid, encouraged the production of lactic acid from second-generation feedstocks. Being wide available, low-cost, and renewable, lignocellulosic ...
Lactic acid bacteria: From food preservation to active packaging
(IOP Publishing Ltd, 2021)
Lactic acid bacteria (LAB) have acted in food fermentations through the ages due to their safety and resilience to specific harsh conditions of high salinity or low pH present in food and gut where they live. Their interaction ...
Sub-lethal exposure of Lacticaseibacillus paracasei to atmospheric nonthermal plasma alters its membrane and response to low pH
(Federation of European Microbiological Societies (FEMS), 2023)
Lactic acid bacteria have an important role in food production, as probiotics and producers of lactic acid. Due to the generation of oxygen and nitrogen-based reactive species and UV radiation, non-thermal plasma (NTP) was ...
