“…Lignin was found relatively difficult to be directly utilized by microorganisms ( Mei et al, 2020 ), thus to improve the degradation rate of lignin is critical. Compared with other bacterial strains ( Guo et al, 2008 ; Seesatat et al, 2020 ), the decomposition capacity of AC-1 on each composition is relatively stronger. Studies of degradation capacity by fungi are extensive and deep ( Sanchez, 2009 ; Wang, Han & Liang, 2017 ) because of its high efficiency, actually fungi are not suitable for large-scale industrial production by the sensitivity to their surroundings and the temperature.…”

In composting, the degradation of lignocellulose in straw is problematic due to its complex structures such as lignin. A common solution to this problem is the addition of exogenous inoculants. AC-1, a stable thermophilic microbial composite, was isolated from high temperature compost samples that can decompose lignocellulose at 50–70 °C. AC-1 had a best degradation efficiency of rice straw at 60 °C (78.92%), of hemicellulose, cellulose and lignin were 82.49%, 97.20% and 20.12%, respectively. It showed degrad-ability on both simple (filter paper, absorbent cotton) and complex (rice straw) cellulose materials. It produced acetic and formic acid during decomposition process and the pH had a trend of first downward then upward. High throughput sequencing revealed the main bacterial components of AC-1 were Tepidimicrobium, Haloplasma, norank-f-Limnochordaceae, Ruminiclostridium and Rhodothermus which provides major theoretical basis for further application of AC-1.

“…13 At present, research on straw saprophytes is mainly focused on medium and high temperatures, which are not suitable for application in a low temperature area. [13][14][15] Few studies have been conducted on straw saprophytes under low temperatures (10 °C-20 °C). 16,17 Nevertheless, there is no research on the degradation of RS at 4 °C.…”

BACKGROUND: Rice straw (RS) is one of the largest sources of lignocellulosic, which is an abundant raw material for biofuels and chemicals. However, the natural degradation of RS under a low temperature environment is the biggest obstacle to returning straw to the field. RESULTS:In the present study, one bacillus strain W118 was isolated. Strain W118 was identified as Bacillus cereus through morphological and physiological characterization and 16S rDNA sequencing. The optimum growth temperature and pH of strain W118 were 20 °C and 6.5, respectively. Simultaneously, it was found that the strain W118 grew well at low temperature, even at a temperature of 4 °C (OD 600 = 1.40 ± 0.01). The decrease of various compositions of RS after the fermentation process at a temperature of 20 °C and 4 °C for 14 days was 27.00 ± 0.02% and 23.70 ± 0.04%, respectively. The composition of RS decreased to 50.71 ± 0.02% after being fermented at 4 °C for 25 days. The results of scanning electron microscopy, Fourier transform infrared spectroscopy and X-ray diffraction of RS showed that the compositions of RS were significant decreased.CONCLUSION: This test suggests that the strain W118 is efficient for degrading RS at low temperature, which has great application potential for straw degradation in a low temperature area.
