Glomalin associated with AMF has a huge potential to promote macroaggregates formation through concurrently binding of microaggregates (Wilson et al., 2009). Soils that contain higher glomalin content may have more water stable aggregates (Table 2). High levels of microaggregates however may limit the necromass induced SCS (Luan et al., 2021 ...The glomalin-related soil protein (GRSP) content was determined using the Battini et al. method.

Structure. Soil structure is classified based on both soil grain shape and size. Structure can be defined as granular, blocky, prismatic, columnar, platy, or single grained. Soil structures are defined by clump sizes which may be less than 0.5 cm in diameter, 1.5-5 cm in diameter, or greater than 5 cm in diameter.Defects at the bulk grain boundaries and heterojunction interfaces could dictate the power losses of perovskite solar cells (PSCs) during the operation process, which are regarded as major roadblocks towards further development of this emerging photovoltaic technology.

A comprehensive understanding of aggregate ...As an insoluble N-linked glycoprotein, glomalin can be quantified from soils as glomalin-related soil protein (GRSP) (Wright and Upadhyaya, 1998). GRSP is also an important fraction of soil organic matter pool, which was estimated to comprise 3 % of soil C and 5 % of soil N (Sousa et al., 2012).from soil microbes. Glomalin, a protein released by mycorrhizal fungi, binds soil particles and improves overall soil structure. The small hyphal strands of mycorrhizal fungi also contribute to improved soil aggregation by binding small particles together. More aggregation results in greater porosity, which often resultsGlomalin is a hypothetical glycoprotein produced abundantly on hyphae and spores of arbuscular mycorrhizal (AM) fungi in soil and in roots. Glomalin was proposed in 1996 by Sara F. Wright, a scientist at the USDA Agricultural Research Service, but it was not isolated and described yet. [1] Glomalin, Additionally, because glomalin is soluble in alkaline pH condition and precipitated under acidic condition (Singh et al., 2017a), thereby increasing glomalin with decreasing soil pH is predicted.
