该团队利用第二种思路,通过设计特异且高效的酶,能够将 PET 塑料催化降解为TPA 和乙二醇(ethylene glycol,EG),而 TPA 和 EG 又是合成新料级 PET 的原料,有望真正实现 PET 的循环再生。 尤生萍说:“这是高品质的循环再生,可完全打通 PET 的‘消费-回收-再生-消费’循环,创造新的 PET 回收途径,有望让 PET...
Ethylene glycol is an industrially important diol in many manufacturing processes and a building block of polymers, such as poly(ethylene terephthalate). In this study, we found that a mycolic acid-containing bacterium Rhodococcus jostii RHA1 can grow with ethylene glycol as ...
为解决 PET 酶法再生的瓶颈,天津大学研究团队通过静电相互作用提升 IsPETase 热稳定性,得到了热稳定性显著提升的突变体,大幅提高了 PET 降解活性和 MHETase 活性。 通过降解高结晶度 PET 得到了单一的对苯二甲酸(Terephthalic acid,TPA)产物,可进一步利用 TPA 合成新料级 Rebirth-PET(Rb-PET)聚酯。 图丨相关论文...
Worsenedkidney and liver diseasesymptoms.If you have normal liver and kidney function, your body can easily remove propylene glycol. About 45% of the compound gets out of the body through the kidneys unchanged. The body breaks down the rest intolactic acid. But in large quantities, lactic acid...

GPR37L1 is an orphan G protein-coupled receptor expressed exclusively in the brain and linked to seizures, neuroprotection and cardiovascular disease. Based upon the observation that fragments of the GPR37L1 N-terminus are found in human cerebrospinal fl
I’m just going to leave this here, for the next time I (or anyone else) want to determine the in-tube concentration of an NMR sample.[1,2] Solvent[Residual] in mM Acetic Acid-d427.1 Acetone-d62.30 Acetonitrile-d313.1 Benzene-d69.52 ...
It’s an Amino Acid. If cold sore returns increase dosage to one 3 times a day. You will never have to deal with cold sores again. Log in to Reply Lily August 31, 2019 at 11:28 am I want to add that we aren’t force fed anything. We are be consumers so it’s our ...
The polymer backbone can be poly(ethylene glycol). The 1-benzotriazolylcarbonate ester can then be reacted directly with a biologically active agent to form a biologically active polymer conjugate or reacted with an amino acid, such as lysine, to form an amino acid derivative....
Crystals of apo-HIPK3 and the two complexes with abemaciclib were cryoprotected with 15–20% ethylene glycol in mother-liquor and flash frozen in liquid nitrogen. Diffraction data for all three samples were collected from a single loop-mounted crystal each, held in stream of liquid nitrogen gas...
