Exploring the coupling coordination mechanism between higher education and environmental governance is conducive to understanding the mutual interactions between them and thus enhancing mutual development. This study constructs the coupling coordination mechanism and the aggregated evaluation index system to measure the mutual coordination relations between them, assesses the performances and the coupling coordination degrees between them in the case of western provincial regions in China, and proposes countermeasures based on the prediction results. It is found that the performances of higher education are relatively more stable than those of environmental governance, and the distributions of the average performance grades exist noticeable geographical differences. Besides, the coupling coordination degrees increase with mild fluctuations with relatively small spatial variations, demonstrating the balanced and similar coordinated development status among regions; furthermore, in the future, the gaps in the coordination status among regions will gradually decline. This study highlights the mutual coordination mechanism between the two subsystems, compares the coupling coordination status among regions both temporally and spatially, and proposes specific, generalizable development suggestions that contribute to the academic sector, policymakers, ecology, and sustainability.
A novel thermophilic actinomycete, designated strain 3-12X, was isolated from mushroom compost in Guangxi University, Nanning, China. The novel isolate contained meso-diaminopimelic acid as the diagnostic diamino acid and the whole-cell sugars were glucose and ribose. The predominant menaquinones were MK-9(H4) and MK-9(H6). The polar phospholipids were diphosphatidylglycerol, hydroxy-phosphatidylethanolamine, phosphatidylmethylethanolamine, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannoside, ninhydrin-positive phosphoglycolipids and glycolipids. Major fatty acids were so-C16 : 0 and C17 : 0. The G+C content of the genomic DNA was 74.6 %. The 16S rRNA gene sequence analysis showed that the closest phylogenetic neighbour of strain 3-12X was Thermomonospora chromogena ATCC 43196 (97.0 %), other closely related strains all belonged to the family Streptosporangiaceae and showed more than 6 % divergence. The chemotaxonomic characteristics of strain 3-12X were significantly different from Thermomonospora chromogena ATCC 43196 and DNA-DNA hybridization showed low relatedness (48.6-55.6 %) between them, so they should be different species. Thermomonospora chromogena was removed from the genus Thermomonospora by Zhang et al. 1998 on the basis of phylogenetic, chemotaxonomic and phenotypic evidence, but its taxonomic position remains uncertain. Based on the phenotypic and phylogenetic data, strain 3-12X represents a novel species in a new genus in the family Streptosporangiaceae. The name Thermostaphylospora griseoalba gen. nov., sp. nov. is proposed. The type strain of Thermostaphylospora grisealba is 3-12X (=DSM 46781=CGMCC 4.7160). We also propose transferring Thermomonospora chromogenaZhang et al. 1998 to Thermostaphylospora chromogena comb. nov. (type strain ATCC 43196=JCM 6244).
A novel thermophilic actinomycete, designated AG2-7 T , was isolated from mushroom residue compost in Guangxi University, Nanning, China. The strain grew optimally at 45-60 6C, at pH 7.0 and with 0-3.0 % (w/v) NaCl. Vegetative mycelia were branched and whitish to pale yellow without fragmentation. Aerial mycelium was abundant, whitish and differentiated into long chains of spores, with a membranous structure or tunica partially covering the surface of aerial hyphae. The non-motile spores were oval in shape with a ridged surface. Strain T contained mesodiaminopimelic acid as the diagnostic diamino acid, and the whole-cell sugars were galactose and ribose. Major fatty acids were iso-C 16 : 0 (27.51 %), iso-C 17 : 0 (10.47 %) and anteiso-C 17 : 0 (12.01 %). MK-9(H 4 ) was the predominant menaquinone. The polar phospholipids were diphosphatidylglycerol, ninhydrin-positive glycophospholipid, phosphatidylinositol, phosphatidylinositol mannoside, phosphatidylethanolamine, phosphatidylmethylethanolamine, an unknown phospholipid and unknown glucosamine-containing phospholipids. The G+C content of the genomic DNA was 63.6 mol%. 16S rRNA gene sequence analysis showed that the organism belonged to the family Pseudonocardiaceae, suborder Pseudonocardineae and showed more than 5 % divergence from other members of the family. Based on the phenotypic and phylogenetic data, strain AG2-7 T represents a novel species of a new genus in the family Pseudonocardiaceae, for which the name Thermotunica guangxiensis gen. nov., sp. nov. is proposed. The type strain of the type species is AG2-7 T (5ATCC BAA-2499 T 5CGMCC T ).The family Pseudonocardiaceae was established by Embley et al. (1988) (Hayakawa & Nonomura, 1987) and incubation at 50 u C in the dark for 3 days under aerobic conditions. The isolate was maintained on modified Sauton's agar (Mordarska et al., 1972) at 4 u C and as suspensions of mycelial fragments in 20 % (v/v) glycerol at 220 u C.Cultural characteristics of strain AG2-7 T were tested on ISP2, ISP3, ISP4, ISP5, ISP6 and ISP7 media (Shirling & Gottlieb, 1966), Gause's asparagine agar (Gause et al., 1983), Bennett's agar (Jones, 1949), Czapek solution agar, potato agar (Waksman, 1961), Sauton's agar, HV medium and water agar (15.0 g agar, 1 l tap water) after incubation for 7 days at 50 u C. Morphological characteristics were observed under a light microscope (80i; Nikon) and a scanning electron microscope (VEGA3 SBU; TESCAN) after incubation for 3-7 days on HV media at 50 u C. Growth temperature and resistance to NaCl was tested on modified Bennett's agar at 4, 16, 28, 37, 40, 45, 50, 55, 60, 65 and 70 u C and observed after 7 and 14 days. Tolerance to NaCl between 0 and 15 % (at intervals of 1 %) was read after 3 and 7 days at 50 u C. The pH range and the optimum pH for growth were examined on Sauton's agar with the pH range between pH 4.0 and 11.0 (in intervals of 1.0 pH unit) using the following buffer systems: for pH 4.0-6.0, 0.1 M citric acid/0.1 M sodium citrate; pH 7.0-9.0, 0.1 M Tris/0.1 M HCl; pH 9.5-10.0, 0...
Two new species of Fulvifomes are described from specimens collected in rainforests of Nonggang Nature Reserve of southern China, based on morphological characteristics and molecular phylogenetic analysis of the internal transcribed spacer (ITS) and nuclear large subunit ribosomal DNA (nLSU) sequences. Fulvifomes nonggangensis sp. nov. is characterized by perennial, sessile and solitary basidiocarps, applanate pileus, small cystidioles of 9.9-15.4 Â 2.9-3.5 lm, large pores of 5-6 per mm, a dimitic hyphal system, and broadly ellipsoid basidiospores of 4.3-5.3 Â 3.3-4.2 lm. F. tubogeneratus sp. nov. is characterized by perennial, sessile, and imbricate basidiocarps, a duplex context, small pores of 7-8 per mm, a dimitic hyphal system, and ovoid to subglobose basidiospores of 5.72 Â 5.00 lm.
During an investigation exploring potential sources of novel thermophilic species and natural products, a novel thermophilic and alkaliphilic actinomycete with alkaline cellulase producing ability, designated strain 4-2-13, was isolated from soil of a tropical rainforest in Xishuangbanna, Yunnan province, China. The morphological and chemotaxonomic characteristics of strain 4-2-13 are consistent with those of the members of the genus Streptomyces. The strain forms extensively branched aerial mycelia and substrate mycelia. Spiral spore chains were observed on aerial mycelia; spores were oval to cylindrical, with smooth surfaces. The organism was found to contain LL-diaminopimelic acid as the diagnostic diamino acid in the cell wall peptidoglycan. The whole cell hydrolysates were found to contain glucose and ribose. The cellular fatty acid profile mainly consists of anteiso-C and iso-C. The menaquinones were identified as MK-9(H), MK-10(H) and MK-9(H). The polar lipids profile were found to consist of diphosphatidylglycerol, phosphatidylmethylethanolamine, a ninhydrin-positive glycophospholipid, phosphatidylinositol, phosphatidylglycerol and unidentified glycolipids. The 16S rRNA gene sequence analysis showed that the organism belongs to the genus Streptomyces and in the 16S rRNA gene tree it formed a distinct phyletic line together with the closely related type strain Streptomyces burgazadensis Z1R7 (95.2% sequence similarity). However, the phenotypic characteristics of strain 4-2-13 are significantly different from those of S. burgazadensis Z1R7. Based on the phenotypic, chemotaxonomic and phylogenetic characteristics, strain 4-2-13 represents a novel species in the genus Streptomyces, for which the name Streptomyces thermoalkaliphilus sp. nov. is proposed. The type strain is 4-2-13 (= DSM 42159 = CGMCC 4. 7205).
