Abstract

The results of the study of low-activity forms of cellulolytic microorganisms in the soils of archaeological sites are presented. The objects of the study were soils with traces of wooden structures in the burials of Vyatichi (12th century). To date, traces of wood do not appear at the macro level. The data we obtained are compared with the results of a laboratory experiment to determine the rates of decomposition of cellulose in soils from various archaeological contexts. Cellulolytic activity was determined by the application method. It was shown that the cellulase activity of soils with traces of funerary wooden structures is 20% of the level of modern soils. This suggests the awakening or presence of living low activity forms of microorganisms that have been preserved in the soil for 800 years.

考古环境中纤维素溶胶微生物的低活性形式
摘要 本文介绍了对考古遗址土壤中低活性纤维素分解微生物的研究结果。研究对象是维亚蒂奇(12 世纪)墓葬中带有木结构痕迹的土壤。迄今为止,在宏观层面上还没有发现木质结构的痕迹。我们将获得的数据与实验室实验结果进行了比较,该实验旨在确定不同考古背景下土壤中纤维素的分解率。纤维素分解活性是通过施用法测定的。结果表明,有墓葬木结构痕迹的土壤的纤维素酶活性是现代土壤的 20%。这表明在土壤中保存了 800 年之久的低活性微生物已经苏醒或存在。

期刊介绍: Biophysics is a multidisciplinary international peer reviewed journal that covers a wide scope of problems related to the main physical mechanisms of processes taking place at different organization levels in biosystems. It includes structure and dynamics of macromolecules, cells and tissues; the influence of environment; energy transformation and transfer; thermodynamics; biological motility; population dynamics and cell differentiation modeling; biomechanics and tissue rheology; nonlinear phenomena, mathematical and cybernetics modeling of complex systems; and computational biology. The journal publishes short communications devoted and review articles.
