Feb 21, 2025 · We analyzed multiple features of PHB and AVA development to assess whether they are dissociable. cdh-4/Fat null mutants did not show a significant PHB/AVA soma positioning defect (Fig. 7, A to D) and the number of synapses between PHB and AVA—assessed with an NLG-1 GRASP reporter—was also unaffected at both L1 and L4 stages (Fig. 7, E and F).

Mar 15, 2022 · Copolymers of poly (3-hydroxybutyrate) (PHB) with comonomers belonging to PHA types have been developed to tackle better processability, higher ductility, and better impact properties. These common copolymers could be listed as poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and poly (3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBH).

Jan 10, 2013 · Polyhydroxybutyrate (PHB) is an attractive substitute for petrochemical plastic due to its similar properties, biocompatibility, and biodegradability. The cost of scaled-up PHB production inhibits its widespread usage.

Feb 20, 2021 · This review uniquely discusses the developments in research on microbial biopolymers, specifically PHB and also gives an overview of current commercial PHB companies making strides in cutting down plastic pollution and greenhouse gases.

May 23, 2013 · Significantly, unlike storage PHB and medium-chain length PHB, cPHB cannot be isolated from cells or organelles by extraction with chloroform. The ubiquitous occurrence of the medium-chain and short-chain polyester, suggests that PHB, like polyisoprenoids, polypeptides, polysaccharides, and polynucleotides, is a fundamental constituent of ...

PHB 是一种重要的碳库，因为它能够在包装、生物医学和环境修复等领域以可生物降解的聚合物形式储存碳，使其成为现有不可再生资源的经济和环境友好的替代品。

Copolymers of poly (3-hydroxybutyrate) (PHB) with comonomers belonging to PHA types have been developed to tackle better processability, higher ductility, and better impact properties.

聚羟基丁酸酯（PHB）是最为常见的PHA，可以CO2为原料，通过 光合自养 、 微生物电合成 、 化学-微生物细胞工厂耦合 等固碳系统合成，但其生产效率和能量效率一直较低，无法满足工业化生产需要。

Dec 12, 2023 · 在本研究中，陈国强教授团队首次发现 H. bluephagenesis 在生产聚（PHB）时利用NADH而非NADPH作为辅因子，从而揭示了在氧限制下增强PHA积累的罕见情况。 为了在氧限制条件下通过提高NADH/NAD+比例以增加PHA的积累，研究人员通过体内和体外两条途径进行改 …

气相色谱法是一种较新、较准确的 PHB测定方法,该法的最大优点在于不需将细胞内 PHB高度纯化即可检测其PHB含量,这对于研究及生产都十分重要,但气相色谱法需要高纯度的 PHB标准样品,还需要有价格昂贵的气相色谱仪。
