“…A study performed with different marine microorganisms and various lignocellulosic biomass sources showed that those with the highest lignocellulolytic activity were Bacillus pumilus , Mesorhizzobium spp., and Aspergillus niger and Trichoderma viride [ 187 ]. In addition, other endophytic fungi and bacteria are also seen as essential biomass degraders and lignocellulolytic enzyme producers [ 188 , 189 , 190 , 191 ].…”

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.

“…The cellulolytic enzymes produced by such microorganisms are a class of glycoside hydrolases and at times contain lignin-modifying biocatalysts [52]. Recently, endophytes were shown to be potential producers of lignocellulolytic enzymes e.g cellulases and hemicellulases [33,53,54].…”

Endophytic fungi are microscopic organisms that live inside plant tissue. They can create a vast array of enzymes and metabolites that present a variety of biological activities without causing any visible indications of their existence. Due to their extensive use in many industries and their simplicity in production, stability, and optimization, fungal enzymes have attracted attention. This paper describes potential applications for the enzymes made by endophytic fungus and explores their use in diverse industries. Additionally, endophytic fungi may develop into fresh sources of industrially valuable enzymes like lipases, amylases, and proteases. Endophytes have rarely been used as sources of industrially relevant enzymes due to the diversity of plants that are readily available. In view of that, search for endophytes from plants with the potential of industrial enzymes is of paramount importance.

“…The viability of enzymes at higher temperatures increases their suitability in extreme conditions during industrial processing. Robl et al (2019) obtained 45 actinomycetes from plants and soils out of which four strains have shown xylanases activity against many hemicellulose substrates. These strains can be exploited in plant biomass degradation specifically sugarcane bagasse.…”

There is an intricate network of relations between endophytic fungi and their hosts that affects the production of various bioactive compounds. Plant-associated endophytic fungi contain industrially important enzymes and have the potential to fulfil their rapid demand in the international market to boost business in technology.Being safe and metabolically active, they have replaced the usage of toxic and harmful chemicals and hold a credible application in biotransformation, bioremediation and industrial processes. Despite these, there are limited reports on fungal endophytes that can directly cater to the demand and supply of industrially stable enzymes. The underlying reasons include low endogenous production and secretion of enzymes from fungal endophytes which have raised concern for widely accepted applications. Hence, it is imperative to augment the biosynthetic and secretory potential of fungal endophytes. Modern state-of-the-art biotechnological technologies aiming at strain improvement using cell factory engineering as well as precise gene editing like Clustered Regularly Interspaced Palindromic Repeats (CRISPR) and its Associated proteins (Cas) systems which can provide a boost in fungal endophyte enzyme production. Additionally, it is vital to characterize optimum conditions to grow one strain with multiple enzymes (OSME). The present review encompasses various plants-derived endophytic fungal enzymes and their applications in various sectors. Furthermore, we postulate the feasibility of new precision approaches with an aim for strain improvement and enhanced enzyme production.
