Abstract Purpose The highly efficient degradation bacteria were selected from the humus from the very cold straw in China for many years to construct the in situ degradation bacteria, and the degradation efficiency of corn straw was determined by process optimization. Methods According to the main components of corn straw, through morphological, physiological, and biochemical screening, three highly efficient complementary degradation strains were selected to construct the compound flora, and the degradation efficiency was analyzed by Fourier transform infrared spectrometer, field emission scanning electron microscope, and X-ray diffractometer. Result The corn straw selected in this paper is mainly composed of cellulose (31.99%), hemicellulose (25.33%), and lignin (14.67%). Through the determination of enzyme activity, strain Streptomyces sp. G1T has high decomposition ability to cellulose and hemicellulose but weak utilization ability to lignin; strain Streptomyces sp. G2T has the strongest decomposition ability to cellulose and hemicellulose among the three strains. The decomposition ability of strain Streptomyces sp. G3T to lignin was the strongest among the three strains. Therefore, by compounding the three strains, the decomposition ability has been greatly improved. The optimal process conditions obtained by single factor and response surface method are as follows: pH is 7, temperature is 30 °C, inoculation amount is 5%, rotational speed is 210 rpm, and the weight loss rate of straw is 60.55% after decomposing for 7 days. A large amount of degradation of corn straw can be seen by Fourier transform infrared spectrometer, field emission scanning electron microscope, and X-ray diffractometer. Conclusion Streptomyces sp. G1T, Streptomyces sp. G2T, and Streptomyces sp. G3T screened from straw humus in very cold areas were used to construct in situ degradation bacteria, which had good straw degradation activity and had the potential to be used for straw treatment in cold areas after harvest. This characteristic makes the complex bacteria become a strong competitive candidate for industrial production, and it is also an effective biotechnology in line with the current recycling of resources.

Research background: Despite the fact, that green growth is one of the main goals of the European Union, a sufficient attention is still not given to it in conditions of Slovakia. The green growth represents compliance of the need to protect environment with economic development of society. So far, a comprehensive survey has not been carried out in Slovakia, which would focus on the issue of green growth and sustainable development in enterprises in the Slovak wood-processing industry. Purpose of the article: The aim of the presented paper is to identify key external and internal determinants preventing the implementation of green growth and sustainable development in enterprises in the Slovak wood-processing industry. Methods: Current information on the research issue was obtained through an empirical survey in the form of a questionnaire. Subsequently, the results were processed descriptively and graphically. Findings & Value added: The achieved results show that the key internal determinant preventing the implementation of green growth and sustainable development in enterprises in the Slovak wood processing industry is the orientation of production to the end of the production process in the context of environmental pollution. The enterprises consider insufficient state support to be the main external determinant.
