“…Recently, ectoine has been the focus of numerous studies due to its outstanding properties, and various bacterial strains and media components (carbon and nitrogen sources) have been investigated to increase its production (Onraedt et al 2005;Chen et al 2020a;Dong et al 2021;Orhan and Ceyran 2022;Orhan et al 2023b). For example, it has been reported that yeast extract is a more efficient carbon source for the production of ectoine by Marinococcus subsp., surpassing other sources such as fructose, starch, glucose, mannitol, glucuronic acid, ethanol, sucrose, glycerol and various oil sources (olive, sunflower and soybean oil) (Wei et al 2011).…”

The production of ectoine, a valuable compound with significant potential as an osmoprotectant, antioxidant, macromolecule protector and anti‐inflammatory agent, was achieved by a lactose‐utilising bacterial strain. We explore the feasibility of using cheese whey, a waste product rich in lactose and amino acids, as a growth medium. The optimisation of various parameters was conducted to maximise ectoine yield. The highest ectoine production was achieved using 50% diluted whey, pH 6.50, 10% NaCl, 150 rpm and 30°C. This is the first study in which whey was efficiently utilised to produce ectoine by Halomonas neptunia.

“…The production was found to be dependent on NaCl concentration and temperature. Additionally, the study identified these bacterial isolates as novel producers of ectoine or hydroxyectoine ( Orhan and Ceyran, 2023 ). All osmolytes share the common characteristic of reducing the osmotic potential in the cytosolic compartment at higher concentrations, without impeding metabolic reactions ( Lou et al, 2018 ).…”

Plant growth and agricultural productivity was greatly limited by soil salinity and alkalization. The application of salt-tolerant rhizobacteria could effectively improve plant tolerance to saline-alkali stress. Micromonospora profundi TRM 95458 was obtained from the rhizosphere of chickpea (Cicer arietinum L.) as a moderate salt-tolerant rhizobacteria. A new osmotic compound (ABAGG) was isolated from the fermentation broth of M. profundi TRM 95458. The chemical structure of the new compound was elucidated by analyzing nuclear magnetic resonance (NMR) and high-resolution mass (HRMS) data. M. profundi TRM 95458 could convert glycerol into ABAGG. The accumulation of ABAGG varied depending on the amount of glycerol and glycine added to the fermentation medium. In addition, the concentration of NaCl affected the ABAGG content obviously. The highest yield of ABAGG was observed when the salt content of the fermentation medium was 10 g/L. The study indicated that salt stress led to the accumulation of ABAGG using glycerol and glycine as substrates, suggesting ABAGG might aid in the survival and adaptation of the strain in saline-alkaline environments as a new osmotic compound.
