The effects of lactic acid bacteria inoculation on the fermentation quality and aerobic stability of king grass silage

Acta Pratacultural Science (2009)

Liu Qinhua Jianguo Zhang LU Xiao-liang

The effects of moisture contents(high,moderate and low) and lactic acid bacteria inoculation(LA,LB and LA+LB) on the fermentation quality and aerobic stability of king grass silage were investigated.All the silages were well preserved.The fermentation quality of king grass silages with moderate moisture content were better than those with high and low moisture content.LA inoculation did not significantly influence the fermentation quality of king grass silage,but the fermentation quality of king grass silages with high and moderate moisture contents was improved.LB or LA+LB inoculation increased the pH value(P0.05) and acetic acid content,but decreased lactic acid content,the rates of lactic acid to acetic acid and lactic acid to total acid(P0.01).When the silages of king grass were exposed to the air,the aerobic stability of LB and LA+LB inoculated silage were best.

Effects of saline irrigation on CO 2 emission and chemical properties of aeolian sandy soil under litter addition

Journal of Applied Ecology (2020)

Shaolei Zhang Jianguo Zhang Wenqian Chang Luyao Wu Afeng Zhang

Calligonum mongolicum is one of the dominant species in the Taklimakan Desert highway shelterbelt, the litter of which plays an important role in carbon cycling. After litter addition, we carried out a laboratory incubation experiment to investigate the dynamics of soil CO2 emission, soil organic carbon (SOC), soluble organic carbon (DOC), pH, and electrical conductivity (EC) under the condition of salt water (SW) and fresh water (FW) with field water holding capacity of 25%, 50%, 75%, and 100%. The results showed that saline water irrigation had an inhibitory effect on soil CO2 emission. Under the four soil water content treatments, the cumulative CO2 emission of freshwater irrigation increased by 1.9%-29.1% compared with that of saline irrigation. Cumulative soil CO2 emissions increased with increasing soil water content. With litter addition, SOC decreased rapidly in the early stage, then gradually increased, and finally tended to be stable. The DOC contents of each treatment following the incubation increased by 41.3%-92.4% compared with that before the incubation. At the end of incubation, soil pH of each treatment increased by 0.20-0.35. The EC increased with the increases of soil water content. Under the four water content conditions and compared with the situation before the incubation, the EC values irrigated with SW increased by 0.11-0.79 mS·cm-1, while those with FW increased or decreased at the end of incubation. Cumulative soil CO2 emission was positively correlated with SOC, DOC, and pH, but not with soil water content. Both saline irrigation and lower water content could inhibit CO2 emission of aeolian sandy soil under litter addition, while EC was significantly affected by the quality of irrigation water and soil water content.

Characterization and Biological Activity of a Novel Exopolysaccharide Produced By Pediococcus Pentosaceus SSC-12 From Silage

Research Square (Research Square) (2021)

Fan Yang Xinqin Li Rong Tian Ruxue Tang Jianguo Zhang

Abstract Background: The exopolysaccharides (EPS) produced by lactic acid bacteria (LAB) are widely used in various fields because of their safety and various biological activities. In this study, we extracted and characterized the composition as well as antioxidant and antibacterial activities of EPS from Pediococcus pentosaceus SSC-12 isolated from the silage. Results: The LAB strain SSC-12 was screened and identified as Pediococcus pentosaceus , based upon 16S rDNA gene sequencing and Neighbor Joining (NJ) phylogenetic analysis. The analysis of the EPS production kinetics results of SSC-12 showed that the EPS production reached the maximum at 20 h of culture. High-performance anion exchange chromatography (HPAEC) analysis showed that the EPS produced by SSC-12 was a heteropolysaccharide comprising glucose (42.6 %), mannose (28.9 %), galactose (16.2 %), arabinose (9.4 %) and rhamnose (2.9 %). The EPS had good antioxidant activity, especially hydroxyl radical scavenging activity. When the concentration of the EPS produced by SSC-12 (SSC-12 EPS) was 10 mg/mL, its 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging ability, hydroxyl radical scavenging ability, superoxide scavenging ability, and reduction ability were 77.4 %, 97.5 %, 77.5 % and 1.3, respectively. At 10 mg/mL，SSC-12 EPS completely killed Staphylococcus aureus GDMCC 1.1220 and substantially inhibited the growth of Salmonella enterica subsp. enterica GDMCC 1.345; however, it had a weak inhibitory effect on Listeria monocytogenes GDMCC 1.347. Conclusions: Due to its strong antioxidant and antibacterial properties, EPS produced by LAB strain SSC-12 have potential application as a bioactive product in the feed, food, and pharmaceutical industries.

Characteristics of new forage rice and effects of additives on its silage quality

Acta Pratacultural Science (2011)

Mingxia Chen Liu Qinhua Jianguo Zhang

Silage as a fermented product is increasingly becoming important to the production of animal husbandry.Rice silage is important to alleviate roughage shortage.The present work investigated the characteristics of new forage rice and effect of additives on its silage fermentation quality and aerobic stability.The ensiling treatments contained the addition of glucose at 2% FM(fresh matter) or pineapple residue at 10% FM,The inoculation of Lactobacillus rhamnosus or L.plantarum,and their combination.The silage fermentation quality and aerobic stability after ensiled for 100 days were investigated.The results showed that new forage rice contained more water soluble carbohydrates and the pH value was near to 4.6 when ensiled without any additives.The combination of L.plantarum and glucose had the best fermentation quality,with lowest pH and contents of acetic acid and NH3-N,highest lactic acid content and ratio of lactic acid to acetic acid.L.rhamnosus inoculation alone had no significant effect on the silage fermentation quality.Glucose or pineapple residue addition had good aerobic stability when they were exposed to the air.

The complete mitochondrial genome of the plant bug Nesidiocoris tenuis (Reuter) (Hemiptera: Miridae: Bryocorinae: Dicyphini)

Zootaxa (2012)

Xun Dai Huaizhu Xun JIAN CHANG Jianguo Zhang Baowen Hu

Nesidiocoris tenuis (Reuter) is a zoophytophagous mirid which is considered both as a significant natural enemy and an important pest of crops. The complete mitochondrial genome (mitogenome) of N. tenuis was determined using long PCR and a primer walking sequencing strategy. The genome is 17, 544 bp in length and contains 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA genes (lrRNA and srRNA), and a duplicate control region. The gene order of this newly sequenced genome is identical with the ground plan of insects. The nucleotide composition is biased toward adenine and thymine with a high AT content (75.0%). The most frequent codons are ATA, TTA, TTT, and ATT. All the PCGs initiate with the standard start codon ATN. All tRNAs have the classic cloverleaf structures, with the exception of tRNASer(UCG), which lacks the dihydrouridine (DHU) arm. Secondary structures of the two ribosomal RNAs were shown referring to previous models. Variable numbers of tandem repeats were detected in the control region. The phylogenetic analyses shows that N. tenuis is the sister group to Lygus lineolaris (Palisot de Beauvois).

Properties and chemical compositions of monovarietal virgin olive oil at different ripening stages: A study on olive cultivation in Northwest China

Agronomy Journal (2023)

Zihan Zhang Zhaoshan Wang Qiaohua Li Min Zhao Jianguo Zhang

Abstract The olive management in China is rarely reported. This study evaluates the influence of drupes ripening on virgin olive oil (VOO) quality of four main varieties ( Olea europaea L., cultivars Ezhi‐8, Koroneiki, Leccion, and Frontoio) cultivated in Northwest China. Quality indices, fatty acid profiles, polyphenols, terpenic acids, tocopherols, and squalene contents are tested at four ripening stages from September to November. The contents of linolenic acid, saturated fatty acids, triterpenic acids, and squalene in all VOO samples decreased during ripening; in contrast, the oleic acid, linoleic acid, nervonic acid (first reported in VOOs), cinnamic acid, p‐coumaric acid, apigenin, and naringenin (contents) increased. The dynamics of the major phenolic compounds, such as hydroxytyrosol, tyrosol, and secoiridoids, were cultivar‐dependent. The two‐way ANOVA and Fisher's LSD test showed that oil compositions varied depending on the ripeness stage and cultivar. Moreover, this latter had more influence than harvest dates on the VOO features. Besides, by applying the orthogonal partial least squares discriminant analysis, several key metabolites (C18:1, oleanolic acid, maslinic acid, oleacein, oleocanthal, and α‐tocopherol) differentiate the four cultivars. In contrast, squalene, oleanolic acid, maslinic acid, oleocanthal, luteolin, and α‐tocopherol could effectively differentiate the four harvesting dates.
