Int J Biol Macromol 2024; 274:133416. [PMID: 38925202 DOI: 10.1016/j.ijbiomac.2024.133416] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2024] [Revised: 06/13/2024] [Accepted: 06/23/2024] [Indexed: 06/28/2024]
Abstract
Bioaugmentation retting with the specialized pectinolytic and xylanolytic microorganisms can accelerate the removal of non-cellulosic macromolecules around plant fibers, thus shortening retting time and facilitating fiber quality. Currently, few specialized microorganisms have been explored for the retting of sisal fibers. The present study excavated the retting fungi including Aspergillus micronesiensis HD 3-6, Penicillium citrinum HD 3-12-3, and Cladosporium sp. HD 4-13 from the region-specific soil samples of planting sisal, and investigated their bioaugmentation retting effects on raw sisal leaves. Results showed that combination of the three fungi achieved the most excellent degumming efficiency (13.69 % of residual gum in sisal fibers) and the highest fiber yield (4.47 %). Furthermore, this fungi combination had the ideal enzymatic hydrolysis features with high activities of pectinase, xylanase and mannanase whereas a low activity of cellulase during the whole retting process, thus endowing the prepared sisal fibers with the lowest mass percentage of non-cellulosic macromolecules (9.76 wt%) and the highest cellulose content (89.23 wt%). SEM and FT-IR analysis further verified that the non-cellulosic substances around sisal fibers were efficiently removed. In summary, the consortia of the three fungi achieved ideal degumming-related enzymes for the removal of non-cellulosic macromolecules, thus acquiring the efficient preparation of sisal fibers.

BIORESOURCE TECHNOLOGY 2024; 395:130373. [PMID: 38278453 DOI: 10.1016/j.biortech.2024.130373] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/08/2023] [Revised: 01/09/2024] [Accepted: 01/21/2024] [Indexed: 01/28/2024]
Abstract
A large quantity of orange peel waste (OPW) is generated per year, yet effective biorefinery methods are lacking. In this study, Trichosporonoides oedocephalis ATCC 16958 was employed for hydrolyzing OPW to produce soluble sugars. Glycosyl hydrolases from Paenibacillussp.LLZ1 which can hydrolyze cellulose and hemicellulose were mined and characterized, with the highest β-mannanase activity of 39.1 U/mg at pH 6.0 and 50 ℃. The enzyme was overexpressed in T. oedocephalis and the sugar production was enhanced by 16 %. The accumulated sugar contains 57 % value-added mannooligosaccharides by the hydrolysis of mannans. The process was intensified by a pretreatment combining H2O2 submergence and steam explosion to remove potential inhibitors. The mannooligosaccharides yield of 6.5 g/L was achieved in flask conversion and increased to 9.7 g/L in a 5-L fermenter. This study improved the effectiveness of orange peel waste processing, and provided a hydrolysis-based methodology for the utilization of fruit wastes.

Abstract
Human population growth, industrialization, and globalization have caused several pressures on the planet's natural resources, culminating in the severe climate and environmental crisis which we are facing. Aiming to remedy and mitigate the impact of human activities on the environment, the use of lignocellulolytic enzymes for biofuel production, food, bioremediation, and other various industries, is presented as a more sustainable alternative. These enzymes are characterized as a group of enzymes capable of breaking down lignocellulosic biomass into its different monomer units, making it accessible for bioconversion into various products and applications in the most diverse industries. Among all the organisms that produce lignocellulolytic enzymes, microorganisms are seen as the primary sources for obtaining them. Therefore, this review proposes to discuss the fundamental aspects of the enzymes forming lignocellulolytic systems and the main microorganisms used to obtain them. In addition, different possible industrial applications for these enzymes will be discussed, as well as information about their production modes and considerations about recent advances and future perspectives in research in pursuit of expanding lignocellulolytic enzyme uses at an industrial scale.

Abstract
Schizophyllum commune is a mushroom-forming fungus well-known for its ability to degrade lignocellulosic materials and production of schizophyllan, a high added-value product for cosmeceutical, pharmaceutical and biomaterial industries. Conventionally, schizophyllan is produced by submerged fermentation using glucose as carbon source. In this work, we demonstrate that alkaline pretreated bagasse can be used by Schizophyllum commune as an alternative carbon source for the production of schizophyllan. The influence of different factors was investigated including cultivation time, biomass loading, and culturing media component and a co-product correlation model was proposed. In this lab-scale study, a yield of 4.4 g/L of schizophyllan containing 89% glucose was achieved. In addition to schizophyllan, the cellulolytic enzymes co-produced during this process were isolated and characterized and could find applications in a range of industrial processes. This demonstrates the potential of using agricultural waste as a cheaper alternative feedstock for this biorefinery process.
