Mini review: Advances in understanding regulation of cellulase enzyme in white-rot basidiomycetes.

Abstract Purpose The textile industry’s previous chemical use resulted in thousands of practical particulate emissions, such as machine component damage and drainage system blockage, both of which have practical implications. Enzyme-based textile processing is cost-effective, environmentally friendly, non-hazardous, and water-saving. The purpose of this review is to give evidence on the potential activity of microbial cellulase in the textile industry, which is mostly confined to the realm of research. Methods This review was progressive by considering peer-reviewed papers linked to microbial cellulase production, and its prospective application for textile industries was appraised and produced to develop this assessment. Articles were divided into two categories based on the results of trustworthy educational journals: methods used to produce the diversity of microorganisms through fermentation processes and such approaches used to produce the diversity of microbes through microbial fermentation. Submerged fermentation (SMF) and solid-state fermentation (SSF) techniques are currently being used to meet industrial demand for microbial cellulase production in the bio textile industry. Results Microbial cellulase is vital for increasing day to day due to its no side effect on the environment and human health becoming increasingly important. In conventional textile processing, the gray cloth was subjected to a series of chemical treatments that involved breaking the dye molecule’s amino group with Cl − , which started and accelerated dye(-resistant) bond cracking. A cellulase enzyme is primarily derived from a variety of microbial species found in various ecological settings as a biotextile/bio-based product technology for future needs in industrial applications. Conclusion Cellulase has been produced for its advantages in cellulose-based textiles, as well as for quality enhancement and fabric maintenance over traditional approaches. Cellulase’s role in the industry was microbial fermentation processes in textile processing which was chosen as an appropriate and environmentally sound solution for a long and healthy lifestyle.

Microbial cellulase production and its potential application for textile industries

Nitrogen-fixing cyanobacteria from the order Nostocales are able to establish symbiotic relationships with diverse plant species. They are promiscuous symbionts as the same strain of cyanobacterium is able to form symbiotic biological nitrogen fixing (BNF) relationships with different plants species. This review will focus on the different types of cyanobacterial-plant associations, both endophytic and epiphytic, and provide insights from a structural viewpoint, as well as our current understanding of the mechanisms involved in the symbiotic crosstalk. In all these symbioses, the benefit for the plant is clear; they obtain from the cyanobacterium, fixed-nitrogen and other bioactive compounds, such as phytohormones, polysaccharides, siderophores or vitamins, leading to enhanced plant growth and productivity. Additionally, there is increasing use of different cyanobacterial species as bio-inoculants for BNF to improve soil fertility and crop production, thus providing an eco-friendly, alternative, and sustainable approach to reduce the over-reliance on synthetic chemical fertilizers.

The production efficiency of water and nitrogen is affected by irrigation and the nitrogen rate. However, it is unclear whether there is a coupling effect of irrigation mode and the timing of nitrogen fertilizer application on rice. Therefore, a two-year field experiment was conducted at two sites with varying cumulative temperatures from 2018 to 2019. The effects of irrigation mode and nitrogen fertilization timing on rice yield and related physiological parameters were examined in different regions. The results showed that sites with different average temperatures had different coupling effects of water and nitrogen on crop growth. The impact of irrigation mode on yield was greater than that of nitrogen fertilizer timing at the site with a 2800 °C annual cumulative temperature (Wanchang). Alternate wetting and drying irrigation increased yield, water production efficiency and nitrogen production efficiency by 8%–10%, 31%–37% and 8%–10%, respectively. In the site with a 2500 °C annual cumulative temperature (Longjing), the coupling effect of irrigation method and nitrogen fertilization timing was significant, and continuously flooded irrigation combined with nitrogen fertilizer (40%:30%:20%:10%) improved rice yield and production efficiency by delaying senescence of leaves and increasing dry matter translocation. The results indicate that combining temperature to explore the optimal coupling mode of irrigation and nitrogen is a promising cropping technique to improve crop productivity and production efficiency in northeastern China. L'efficacité de la production d'eau et d'azote est affectée par l'irrigation et le taux d'azote. Cependant, il n'est pas clair s'il existe un effet de l'association du mode d'irrigation et du moment de l'application de l'engrais azoté sur le riz. Par conséquent, une expérience de terrain a été menée au cours de deux ans de 2018 à 2019 sur deux sites ayant des températures cumulatives variables. Les effets du mode d'irrigation et du moment de l'application de l'engrais azoté sur le rendement du riz et les paramètres physiologiques connexes ont été étudiés dans différentes régions. Les résultats ont montré que les sites présentant des températures moyennes différentes avaient des effets d'association différents de l'eau et de l'azote sur la croissance des cultures. L'impact du mode d'irrigation sur le rendement était plus important que celui d'engrais azoté sur le site présentant une température cumulative annuelle de 2,800 °C (Wanchang). L'irrigation alternée par mouillage et séchage a augmenté le rendement, l'efficience de la production d'eau et l'efficience de la production d'azote de 8–10%, 31–37% et 8–10%, respectivement. Sur le site où la température cumulative annuelle est de 2,500 °C (Longjing), l'effet de l'association de la méthode d'irrigation et du moment de l'application de l'engrais azoté était significatif, et l'irrigation par inondation continue combinée au engrais azoté (40%: 30%: 20%: 10%) a amélioré le rendement du riz et l'efficacité de la production en retardant la sénescence des feuilles et en augmentant le déplacement de la matière sèche. Les résultats indiquent que la combinaison de la température pour explorer le mode d'association optimale de l'irrigation et de l'azote est une technique agricole prometteuse pour améliorer la productivité agricole et l'efficacité de la production au nord-est de la Chine.

Interaction of the coupled effects of irrigation mode and nitrogen fertilizer timing on rice yield in different regions

The family of phosphate transporters (PHTs) mediates the uptake and translocation of Pi inside the plants. However, little is known about transporters in soybean. Therefore, Searched the Genome Database for Soybean, 57 GmPHTs family members were identified in soybean, Phylogenetic analysis suggested that members of the PHTs gene family can be divided into six clades. Collinearity analysis revealed that most of the GmPHT genes shared syntenic relationships with PHTs members in Arabidopsis thaliana and that large segment duplication played a major driving force for GmPHTs evolution in addition to tandem duplication. Further analysis of the promoter revealed that light-responsive elements and abiotic stress-responsive elements were widely distributed within the promoter regions of GmPHT genes. Based on RNA-seq data, GmPHTs showed different expression patterns in roots and leaves of soybean treated with long-term low phosphorus and short-term low phosphorus, in addition, the expression levels of GmPHT genes can be regulated by drought stresses, it was implied that the induced expression of GmPHTs could promote phosphorus uptake and transport in soybean and thus adapt to low phosphorus and drought stress, which is the first step dissection of Pi transport system and probably refers to new roles of PHTs genes in soybean.
