Abstract
Cement is the most widely used construction material due to its strength and affordability, but its production is energy intensive. Thus, the need to replace cement with widely available waste material such as incinerated black filter cake (IBFC) in order to reduce energy consumption and the associated CO2 emissions. However, because IBFC is a newly discovered cement replacement material, several parameters affecting the mechanical properties of IBFC-cement composite have not been thoroughly investigated yet. Thus, this work aims to investigate the impact of IBFC as a cement replacement and the addition of the calcifying bacterium Lysinibacillus sp. WH on the mechanical and self-healing properties of IBFC cement pastes. The properties of the IBFC-cement pastes were assessed by determining compressive strength, permeable void, water absorption, cement hydration product, and self-healing property. Increases in IBFC replacement reduced the durability of the cement pastes. The addition of the strain WH to IBFC cement pastes, resulting in biocement, increased the strength of the IBFC-cement composite. A 20% IBFC cement-replacement was determined to be the ideal ratio for producing biocement in this study, with a lower void percentage and water absorption value. Adding strain WH decreases pore sizes, densifies the matrix in ≤ 20% IBFC biocement, and enhances the formation of calcium silicate hydrate (C-S-H) and AFm ettringite phases. Biogenic CaCO3 and C-S-H significantly increase IBFC composite strength, especially at ≤ 20% IBFC replacement. Moreover, IBFC-cement composites with strain WH exhibit self-healing properties, with bacteria precipitating CaCO3 crystals to bridge cracks within two weeks. Overall, this work provides an approach to produce a "green/sustainable" cement using biologically enabled self-healing characteristics.

Abstract
There is an increasing interest in finding eco-friendly and safe approaches to increase agricultural productivity and deliver healthy foods. Arbuscular mycorrhizal fungi (AMF) and endophytic fungi (EPF) are important components of sustainable agriculture in view of their ability to increase productivity and various plant secondary metabolites with health-promoting effects. In a pot experiment, our main research question was to evaluate the additive and synergistic effects of an AMF and four root-endophytic fungi on plant performance and on the accumulation of health-promoting secondary compounds. Plant growth varied between the treatments with both single inoculants and co-inoculation of an AMF and four EPF strains. We found that inoculation with a single EPF positively affected the growth and biomass production of most of the plant-endophyte consortia examined. The introduction of AMF into this experiment (dual inoculation) had a beneficial effect on plant growth and yield. AMF, Rhizophagus variabilis KS-02 co-inoculated with EPF, Trichoderma zelobreve PBMP16 increased the highest biomass, exceeding the growth rate of non-inoculated plants. Co-inoculated R. variabilis KS-02 and T. zelobreve PBMP16 had significantly greater beneficial effects on almost all aspects of plant growth, photosynthesis-related parameters, and yield. It also promoted root growth quality and plant nutrient uptake. The phenolic compounds, anthocyanin, and antioxidant capacity in rice seeds harvested from plants co-inoculated with AMF and EPF were dramatically increased compared with those from non-inoculated plants. In conclusion, our results indicated that EPF and AMF contributed to symbiosis in Maled Phai cultivar and were coordinately involved in promoting plant growth performance under a pot trial.

Abstract
Antimicrobial resistance is a growing health concern. Antimicrobial peptides are a potential solution because they bypass conventional drug resistance mechanisms. Previously, we isolated a peptide from Crocodylus siamensis hemoglobin hydrolysate, which has antimicrobial activity and identified the main peptide from this mixture (QL17). The objective of this work was to evaluate and rationally modify QL17 in order to: (1) control its mechanism of action through bacterial membrane disruption; (2) improve its antimicrobial activity; and (3) ensure it has low cytotoxicity against normal eukaryotic cells. QL17 was rationally designed using physicochemical and template-based methods. These new peptide variants were assessed for: (1) their in vitro inhibition of microbial growth, (2) their cytotoxicity against normal cells, (3) their selectivity for microbes, and (4) the mode of action against bacteria using scanning electron microscopy (SEM), transmission electron microscopy (TEM) and confocal microscopy. The results indicate that all designed peptides have more potent antimicrobial efficacy than QL17 and IL15 peptides. However, only the most rationally modified peptides showed strong antimicrobial activity and minimal toxicity against normal cells. In particular, IL15.3 (hydrophobicity of 47% and net charge of + 6) was a potent antimicrobial agent (MIC = 4-12 μg/mL; MBC = 6-25 μg/mL) and displayed excellent selectivity for microbes (cf. human cells) via FACS assays. Microscopy confirmed that IL15.3 acts against bacteria by disrupting the cell membrane integrity and penetrating into the membrane. This causes the release of intracellular content into the outer environment leading to the death of bacteria. Moreover, IL15.3 can also interact with DNA suggesting it could have dual mode of action. Overall, a novel variant of QL17 is described that increases antimicrobial activity by over 1000-fold (~ 5 μg/mL MIC) and has minimal cytotoxicity. It may have applications in clinical use to treat and safeguard against bacteria.

Abstract
Rice (Oryza sativa L.) is one of the most popular cereal crops, being consumed by almost half of the world's population. Among several cultivars widely distributed in Thailand, Maled Phai is a Thai pigmented-upland rice with exceptionally high nutritional value and high demand in the local Thai market. This study aimed to investigate the feasibility of producing plant growth-promoting properties (PGP) and enhancing the accumulation of phytochemicals in Maled Phai rice seeds of endophytic fungi isolated from upland black rice. Among a total of 56 isolates, the 4 most effective PGP isolates were identified as Trichoderma zelobreve PBMP16, Talaromyces pinophilus PBMP28, Aspergillus flavus KKMP34, and Trichoderma sp. PBMP4 based on their morphological characteristics and multigene (ITS, rpb2, tef-1, CaM, and BenA) phylogenetic analyses. These four endophytic fungi could promote plant growth parameters under greenhouse conditions. Outstandingly, upland rice inoculated with Tr. zelobreve PBMP16 had a significant increase in total seed weight, root length, phenolic compounds, anthocyanin, antioxidants, and N uptake, which were higher than those of the noninoculated control, and even better than the chemical fertilizer. Overall, this report shows that endophytic fungi efficiently promoted growth and increased the phenolic compounds, anthocyanin, and antioxidants of Maled Phai rice.

Abstract
Helianthus tuberosus L. (Jerusalem artichoke) produce inulin, a type of fructan, which possesses several biotechnology applications, e.g., sugar syrup, prebiotics, fiber in diabetic food, enabling blood sugar and cholesterol reduction. Drought reduces inulin accumulation in the tubers of Jerusalem artichoke as the plants protect themselves from this stress by induction of stress gene responses, effecting growth reduction. Endophytic bacteria are promising candidates to promote plant growth and yield particularly under abiotic stress. Therefore, three endophytic bacteria with plant growth promoting properties were examined for their ability to improve Jerusalem artichoke growth and yield under both well-watered and drought conditions when inoculated individually or in combinations in pot experiments with 2 factorial random complete block design. The interactions of the endophytic bacteria and plant host determined the differential gene expression in response to drought as revealed by quantitative polymerase chain reaction. Single inoculum of the endophytic bacteria increased the height, weight, root traits, and harvest index of Jerusalem artichoke compared to co-inocula under both well-watered and drought conditions. However, the co-inocula of Rossellomorea aquimaris strain 3.13 and Bacillus velezensis strain 5.18 proved to be a synergistic combination leading to high inulin accumulation; while the co-inocula of B. velezensis strain 5.18 and Micrococcus luteus strain 4.43 were not beneficial when used in combination. The genes, dehydrin like protein and ethylene responsive element binding factor, were upregulated in the plants inoculated with single inoculum and co-inocula of all endophytic bacteria during drought stress. Moreover, the gene expression of indole-3-acetic acid (IAA) amido synthetase were up-regulated in Jerusalem artichoke inoculated with M. luteus strain 4.43 during drought stress. The fructan:fructan 1-fructosyltransferase (1-FFT) was also stimulated by the endophytic bacteria particularly in drought condition; the results of this study could explain the relationship between endophytic bacteria and plant host for growth and yield promotion under well-watered and drought conditions.

Abstract
Rhizobacteria are well recognized for their beneficial multifunctions as key promoters of plant development, suppressing pathogens, and improving soil health. In this study, experiments focused on characterizing the plant growth promotion (PGP) and extracellular hydrolase production traits of rhizobacteria, and their impact on Jerusalem artichoke growth. A total of 50 isolates proved capable of either direct PGP or hydrolase-producing traits. Two promising strains (Enterobacter cloacae S81 and Pseudomonas azotoformans C2-114) showed potential on phosphate and potassium solubilization, IAA production, and 1-aminocyclopropane-1-carboxylic acid deaminase activity and hydrolase production. A hydrolase-producing strain (Bacillus subtilis S42) was able to generate cellulase, protease, amylase, β-glucosidase, and phosphatase. These three selected strains also gave positive results for indirect PGP traits such as siderophore, ammonia, oxalate oxidase, polyamine, exopolysaccharide, biofilm, motility, and tolerance to salinity and drought stress. Colonization was observed using a scanning electron microscope and rhizobacteria appeared at the root surface. Interestingly, inoculation with consortia strains (S42, S81, and C2-114) significantly increased all plant parameters, including height, biomass, root (length, surface, diameter, and volume), and tuber fresh weight. Therefore, we recommend that potential consortia of PGP and hydrolase-producing rhizobacteria be employed as a biofertilizer to improve soil and boost crop productivity.

Abstract
Endophytic bacteria refer to bacteria which promote plant growth via direct and indirect mechanisms. Three endophytic bacteria isolated from Jerusalem artichoke exhibited plant growth induction and inulin production. These bacteria had functions of fructan degradation and synthesis from inulinase and levansucrase, respectively. Rossellomorea aquimaris 3.13 and Priestia megaterium 3.5 obtained inulinase/levanase enzyme with inulin and levan as substrates; enzyme production showed the optimum conditions in 1% inulin medium of 35 °C, pH 7.0. Bacillus velezensis 5.18 and Priestia megaterium 3.5 had inulosucrase/levansucrase enzyme with sucrose as a major carbon source; the enzyme had optimum temperature and pH conditions of 30 °C and pH 7.0, respectively. A combination of carbon sources had effect on decreasing enzyme activity; in addition, co-inoculation of bacteria showed a slight difference in enzyme production compared with single inoculation. The inulosucrase/levansucrase was produced earlier in co-culture containing bacteria with inulinase activity. Plant fructan synthesis was involved in 1-SST and 1-FFT, while 1-FEH encoded inulin degradation; these genes were evaluated in Jerusalem artichoke inoculated with the endophytic bacteria to quantify gene expression level using qPCR. All genes expressed in low levels at early stage of growth, responding to all endophytic bacteria. Significantly, Bacillus velezensis 5.18 induced all genes of the plant at 65 days of inoculation; Rossellomorea aquimaris 3.13 induced 1-FFT while Priestia megaterium 3.5 induced 1-SST.

Abstract
Due to different functions of phosphate solubilizing bacteria (PSB) and arbuscular mycorrhizal fungi (AMF), their potential synergistic effects on enhancing plant growth and yield are worth investigating, especially under adverse conditions. This work focused on the isolation of PSB and characterization for their plant growth promoting properties under drought. The most efficient P solubilizing bacterium was isolated and identified as Burkholderia vietnamiensis strain KKUT8-1. Then, a factorial experiment on the performance of sunchoke (Helianthus tuberosus) was set up with four factors, viz., PSB (presence or absence of KKUT8-1), AMF (presence or absence of Rhizophagus aggregatus), rock phosphate (RP; added or not) and moisture (well-watered (WW) or drought (DS) conditions). Sunchoke performance was enhanced by the presence of AMF, whereas addition of PSB had a positive effect on SPAD values and inulin concentration. Drought reduced plant performance, while addition of RP reduced photosynthetic rate. There was little evidence for synergistic effects between PSB and AMF, except for SPAD values and inulin concentration. Plants that were co-inoculated with AMF and PSB had highest SPAD value, shoot diameter, leaf area, leaf number, chlorophyll concentration, plant biomass, tuber production, root growth and total soluble sugar concentration. Co-inoculated plants also had increased plant water status, reduced electrolyte leakage, and reduced malondialdehyde and proline concentration. Strain KKUT8-1 is the first strain of B. vietnamiensis capable of promoting growth and yield of sunchoke. Enhanced production of sunchoke by a combination of AMF and PSB was much better than the application of RP. Our finding offers an opportunity to develop combinations of biological inoculants for increasing the growth and production of sunchoke under drought in the future.

Abstract
This study aimed to investigate the efficiency of arbuscular mycorrhizal fungi (AMF) to promote growth and cannabinoid yield of Cannabis sativa KKU05. A completely randomized design (CRD) was conducted with six replications for 60 days. Two different species of AMF, Rhizophagus prolifer PC2-2 and R. aggregatus BM-3 g3 were selected as inocula and compared with two non-mycorrhizal controls, one without synthetic fertilizer and one with synthetic NPK fertilizer. The unfertilized non-mycorrhizal plants had the lowest performance, whereas plants inoculated with R. aggregatus BM-3 g3 performed best, both in terms of plant biomass and concentrations of CBD and THC. There were no significant differences in plant biomass and cannabinoid concentrations between non-mycorrhizal plants that received synthetic fertilizer and mycorrhizal plants with inoculum of R. prolifer PC2-2. Our data demonstrate the great potential for cannabis cultivation without risking deterioration of soil structure, such as soil hardening and increased acidity, which might be induced by long-term use of synthetic fertilizer.

Abstract
BACKGROUND Biocement, calcifying bacteria-incorporated cement, offers an environmentally-friendly way to increase the cement lifespan. This work aimed to investigate the potential use of Lysinibacillus sp. strain YL towards biocement application in both theoretical and experimental ways. METHODS AND RESULTS Strain YL was grown using calcium acetate (Ca(C2 H3 O2 )2 ), calcium chloride (CaCl2 ) and calcium nitrate (Ca(NO3 )2 ). Maximum bacterial growth of ~0.09 hr-1 and the highest amount of CaCO3 precipitation of ~8.0 g/L were obtained when using Ca(C2 H3 O2 )2 . The SEM and XRD results confirmed that biogenic CaCO3 were calcites. The bulk, Young's and shear moduli of biogenic CaCO3 calculated via the VRH approximation were ~1.5-2.3 times larger than those of ordinary Portland cement. The Poisson's ratio was 0.382 and negative in some directions, suggesting its ductility and auxetic behaviors. The new model was developed to explain the growth kinetic of strain YL in the presence of Ca(C2 H3 O2 )2 , whose concentration was optimized for biocement experiments. Strain YL could increase the compressive strength of cement up to ~50% higher than that of the uninoculated cement. CONCLUSION Strain YL is a promising candidate for biocement applications. This work represents the trials of experiments and models allowing quantitatively comparison with large-scale production in the future.

Abstract
Three new indole diterpenoids, aculeatupenes A-C (1-3), together with four known compounds (4-7), were isolated from the mycelium of Aspergillus aculeatus KKU-CT2. Their structures were established by spectroscopic evidence and absolute configurations of 1-3 were determined by comparison of their experimental and calculated ECD spectra. Compounds 1, 2, and emindole SB (4) showed weak cytotoxicity against HelaS3, KB, HepG2, MCF-7, and A549 cancer cell lines with IC50 values in the range of 11.12-67.81 μM. Compound 3 showed weak cytotoxicity against HelaS3 cell lines with an IC50 value of 17.48 μM but non-cytotoxicity against Vero cell line. In addition, compound 1 exhibited weak antibacterial activity against Bacillus cereus.

Abstract
In this work, the effects of co-inoculation between an arbuscular mycorrhizal fungus (AMF) and a phosphate solubilizing bacteria (PSB) to promote the growth and production of sunchoke under field condition were investigated during 2016 and 2017. Four treatments were set up as follows: plants without inoculation, with AMF inoculation, with PSB inoculation and with co-inoculation of PSB and AMF. The results showed the presence of PSB and AMF colonization at the harvest stage in both years. This suggested the survival of PSB and successful AMF colonization throughout the experiments. According to correlation analysis, PSB positively affected AMF spore density and colonization rate. Also, both AMF and PSB positively correlated with growth and production of sunchoke. Co-inoculation could enhance various plant parameters. However, better results in 2016 were found in co-inoculation treatment, while AMF inoculation performed the best in 2017. All of these results suggested that our AMF and PSB could effectively promote growth and production of sunchoke under field conditions. Such effects were varied due to different environmental conditions each year. Note that this is the first study showing successful co-inoculation of AMF and PSB for promoting growth and yield of sunchoke in the real cultivation fields.

Abstract
Soil salinity affects soil quality and reduces plant performance. Arbuscular mycorrhizal fungi (AMF) can enhance the tolerance of plants under salinity stress. Cultivation of eucalyptus (Eucalyptus camaldulensis), which exhibits high water use efficiency, is possible in saline areas to produce raw materials for the pulp industry. We determined the effects of arbuscular mycorrhizal fungi (AMF) on the growth and survival of eucalyptus seedlings under saline conditions. Three different clones of eucalyptus seedlings were pre-inoculated with three salt-tolerant AMF species, namely Glomus sp.2, Gigaspora albida and G. decipiens, and without pre-inoculation. The seedlings were grown in a greenhouse for 45 days. They were then transferred to individual pots, filled with field soil and subsequently treated with NaCl solution until electro-conductivity (EC) reached 10, 15 and 20 dS m-1. They were watered for 90 days under nursery conditions. The results show that increased salinity levels reduced plant performance, fractional AMF root colonization, spore number, and eucalypt K/Na ratio. AMF significantly increased chlorophyll and decreased leaf proline concentrations by more than 50% and 20% respectively and increased the K/Na ratio three- to six-fold compared with non-inoculated plants. Pre-inoculation with AMF before outplanting also improved plant performance by more than 30% under salinity stress compared to non-inoculated plants. We conclude that AMF can alleviate the negative impacts of salinity on plant physiological and biochemical parameters.

Abstract
We investigated the properties of the low molecular weight thermo-alkali-stable and mercury ion-tolerant xylanase production from Thermomyces dupontii KKU-CLD-E2-3. The xylanase was purified to homogeneity by ammonium sulfate, Sephadex G-100 and DEAE-cellulose column chromatography which resulted 27.92-fold purification specific activity of 56.19 U/mg protein and a recovery yield of 2.01%. The purified xylanase showed a molecular weight of 25 kDa by SDS-PAGE and the partial peptide sequence showed maximum sequence homology to the endo-1,4-β-xylanase. The optimum temperature and pH for its activity were 80 °C and pH 9.0, respectively. Furthermore, the purified xylanase can maintain more than 75% of the original activity in pH range of 7.0-10.0 after incubation at 4 °C for 24 h, and can still maintain more than 70% of original activity after incubating at 70 °C for 90 min. Our purified xylanase was activated by Cu2+ and Hg2+ up to 277% and 235% of initial activity, respectively but inhibited by Co2+, Ag+ and SDS at a concentration of 5 mM. The Km and Vmax values of beechwood xylan were 3.38 mg/mL and 625 µmol/min/mg, respectively. Furthermore, our xylanase had activity specifically to xylan-containing substrates and hydrolyzed beechwood xylan, and the end products mainly were xylotetraose and xylobiose. The results suggested that our purified xylanase has potential to use for pulp bleaching in the pulp and paper industry.

Abstract
The bioactive compounds of the fungus Aspergillus aculeatus strain KKU-CT2, have been studied. The crude extracts from this fungus showed good antimicrobial activity against human pathogens, including Gram-positive and Gram-negative bacteria and yeast-like fungi. Its chemical components were isolated and purified by chromatographic methods. The structures of the secondary metabolites were elucidated by spectroscopic methods (IR, 1H, and 13C NMR). They were identified as ergosterol peroxide (1), secalonic acid D (2), secalonic acid F (3), variecolin (4), variecolactone (5), and ergosterol (6). Compounds 1 and 4-6 are reported for the first time as fungal metabolites from this species. Compound 1 displayed inhibitory effects on HSV-1 with an IC50 of 11.01 μg/ml. Compounds 3, 4, and 6 exhibited antimalarial activity against Plasmodium falciparum with IC50 of 1.03, 1.47, and 5.31 µg/ml, respectively. Additionally, all compounds from A. aculeatus KKU-CT2 showed unprecedented anticancer activities against human epidermoid carcinoma in the mouth (KB) (compounds 1-6), human breast cancer (MCF-7) (compounds 2, 4, and 5), and human lung cancer cells (NCI-H187) (compounds 1-4 and 6). These results suggest that secondary metabolites from A. aculeatus KKU-CT2 might be interesting for further derivatization, targeting diseases such as cancer.

Abstract
Four meroterpenoids, 1-hydroxychevalone C, 1-acetoxychevalone C, 1,11-dihydroxychevalone C, and 11-hydroxychevalone C and two ester epimers, 2S,4S-spinosate and 2S,4R-spinosate, together with seven known compounds, chevalones B, C, and E, tryptoquivaline, nortryptoquivaline, tryptoquivaline L, and quinadoline A were isolated from the fungus Neosartorya spinosa. Their structures were established based on spectroscopic data analyses. The theoretical ECD spectra of epimers, 2S,4S-spinosate and 2S,4R-spinosate were calculated to support the experimental results of their CD spectra. 1-hydroxychevalone C exhibited antimycobacterial activity against Mycobacterium tuberculosis with a MIC value of 26.4 μM. 1-Acetoxychevalone C and tryptoquivaline showed antimalarial activity against Plasmodium falciparum with IC50 values of 6.67 and 2.65 μM, respectively. In addition, 1-hydroxychevalone C, 1-acetoxychevalone C, 1,11-dihydroxychevalone C and quinadoline A showed cytotoxicity against KB and NCI-H187 cancer cell lines with IC50 values in the range of 32.7-103.3 μM.

Abstract
A new meroterpenoid, named tatenoic acid (1), was isolated from the fungus Neosartorya tatenoi KKU-2NK23, together with five known compounds, aszonapyrones A and B (2 and 3), aszonalenin (4), ergosterol (5) and D-mannitol (6). Their structures were established on the basis of spectroscopic methods. Aszonapyrones A (2) exhibited antimalarial activity against Plasmodium falciparum, and it also exhibited cytotoxicity against two cancer cell lines, NCI-H187 and KB.

Abstract
The nucleotide sequence of the xylanase encoding gene in Scytalidium thermophilum Af101-3 was determined. The gene encodes a family G/11 xylanase, and the coding region is interrupted by a 72 bp intron. Transcription of the gene was investigated by reverse transcription PCR (RT-PCR). Transcription of the gene was not affected by the presence of 2% glucose in the medium. Xylanase production in S. thermophilum Af101-3 was also affected by concentration of glucose in the medium (modified Czapek's supplemented with 2% corn cob powder and 0.1% glucose). Therefore, xylanase expression in this fungus may not be regulated by the carbon source in the medium.

Abstract
We describe the molecular characteristics of Scytalidium thermophilum isolated from Japanese soil. The S. thermophilum isolates produced higher xylanase activity than Humicola lanuginosa isolated from Japanese soil. A G/11 family xylanase-encoding gene was detected in the S. thermophilum genome by using the polymerase chain reaction technique. The S. thermophilum AF101-3 strain, which was one of the isolates in this study, grew well at 37 degrees C and 50 degrees C, and contained the maximum xylanase activity detected among the isolates. Phylogenetic analysis revealed that the S. thermophilum strains isolated from Japanese soil were clustered in a different group from the S. thermophilum strains reported by Lyons et al. [Mycol Res 104:1431, 2000], suggesting that the S. thermophilum strains isolated in this study are genetically new isolates. Therefore, the genetic diversity of S. thermophilum might be higher than that of H. lanuginosa. Moreover, this is the first report about detection of a xylanase-encoding gene in S. thermophilum.
