Exploring the potential of a bioassembler for protein crystallization in space

mycolabadmin

Scientists successfully grew high-quality protein crystals in space using an innovative magnetic bioassembler device. By taking advantage of the weightless environment aboard the International Space Station, they were able to grow protein crystals with excellent structural quality that matched or exceeded Earth-based methods. This breakthrough demonstrates that space-based protein crystallization could help scientists better understand protein structures and potentially accelerate drug development.

The glycolipid flocculosin-A from the fungus Anthracocystis flocculosa, or how to deal with cotton-wool-like crystals

mycolabadmin

Scientists successfully determined the three-dimensional structure of flocculosin-A, a powerful antifungal compound produced by a fungus called Anthracocystis flocculosa. The main challenge was that the compound naturally forms very thin, needle-like crystals unsuitable for analysis. By using a special cooling and heating cycle, researchers were able to grow better crystals and use X-ray diffraction to reveal the compound’s complete molecular structure, which contains a sugar backbone connected to two fatty acid chains with specific arrangements.

Nanoscale Characterization of Fungal-Induced CaCO3 Precipitation: Implications for Self-Healing Concrete

mycolabadmin

Researchers studied how fungi can help repair concrete cracks by producing calcium carbonate (similar to limestone) using advanced microscopy techniques. They found that three types of fungi all produced stable calcite crystals, which is good for making durable self-healing concrete. The study shows exactly how fungi work at the tiny nanoscale level to create these minerals, providing important information for developing better crack-healing concrete that could reduce environmental impact.
