“…Depending on the type of hydrate and the guest gas molecules, the effect of the amino acid may differ. For example, in the case of methane hydrate, tryptophan or leucine acts as a good hydrate promoter, while in the case of ethane and THF hydrates, leucine shows weak hydrate-growth promotion. , …”

“…For example, in the case of methane hydrate, tryptophan or leucine acts as a good hydrate promoter, while in the case of ethane and THF hydrates, leucine shows weak hydrate-growth promotion. 18,19 Li et al have studied an alanine-rich short peptide as an inhibitor that limits the growth of hydrate by adsorbing to the interface of the formed hydrate and controlling mass transfer from the liquid side for further hydrate formation. They concluded that the peptide-folding characteristics, as well as its length and sequence, were the significant parameters that controlled the binding of the peptide at the hydrate/water interface.…”

Clathrate hydrates are nonstoichiometric crystalline inclusion compounds. Water acts as a “host lattice” and traps small guest molecules in stable cavities. One example, methane hydrates, are especially prevalent in situ at the seafloor. Although microorganism-produced proteins and polypeptides, including marine methylotroph porin proteins, can accelerate methane hydrate formation under conditions simulating their natural occurrence at the seafloor, the role that particular peptide sequences play in biocatalytic hydrate kinetics enhancement is unclear, especially the underlying molecular-level mechanisms. Here, we reveal the peptide-focused regulation of microorganisms’ role in managing marine hydrates via an approximation mechanism of enzymatic catalysis accelerating hydrate formation. Aside from control of hydrate kinetics per se, we speculate that this peptide-centric mechanistic understanding could lead to a re-evaluation of the extent and geological importance of bioregulation of methane turnover in the biosphere.

“…Various technological solutions make it possible to intensify the process of hydrate formation by increasing a contact surface of phases. They accelerate the process of hydrate formation [18,19]. Fine-dispersed water or solutions containing additives-promoters into the volume of gas, such as SAS (Surface Active Substance), high-speed mixing of systems, including mixing by barbotage, etc.…”

“…Amino acids as green gas hydrate inhibitors have attracted more attention since Sa et al reported their inhibition impact on CO 2 hydrates 23 . Amino acids are capable of forming hydrogen bonds with water molecules due to the presence of both amine and carboxyl groups in their structure 16,22,24 . Like ionic liquids, amino acids have not been proven to compete and replace commercial THIs.…”

“…Like ionic liquids, amino acids have not been proven to compete and replace commercial THIs. In view of this, researches have been conducted to examine the performance of combining different thermodynamic inhibitors 24 .

This paper presents an experimental and modeling studies on the thermodynamic inhibition effects of the mixture of monoethlyene glycol (MEG) and glycine (Gly) on the carbon dioxide hydrate phase boundary condition. The monoethlyene glycol and glycine (1:1) mixture inhibition effects were investigated at concentrations of 5, 10, and 15 wt.% and pressure ranges from 2.0–4.0 MPa. The effects of the proposed mixture on the carbon dioxide hydrate phase boundary were evaluated by measuring the dissociation temperature of carbon dioxide hydrate using a T-cycle method. The synergistic effect was evaluated based on comparison with pure MEG and Gly data. The results show that 15 wt.% of MEG and Gly mixture displays the highest inhibition effect compared to the 5 and 10 wt.% mixtures, respectively. However, the synergistic effect is higher at 10 wt.%. Dickens' model was also adopted to predict the phase equilibrium data of CO2 hydrates in the presence of the mixture. The modified model successfully predicted the data within a maximum error of ± 0.52 K.
