“…On the other hand, solid-state fermentation is carried out on a solid and insoluble substrate without free liquid. In this type of fermentation, in addition to physical support, the substrate also provides the source of nutrients for the microorganism’s growth [ 223 , 224 ].…”

“…On the other hand, despite requiring a medium that maintains the necessary moisture for microbial growth, the solid-state fermentation technique presents a more accessible microorganism adaptation to the substrate, less contamination risk, and less water and energy needed, in addition to higher yield compared to submerged fermentation [ 226 ]. Thus, solid-state fermentation has been seen as an essential alternative for lignocellulosic biomass hydrolysis and subsequent production of by-products [ 223 , 227 ].…”

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.

Maize stover was explored as a sole substrate of carbon for the extra cellular production of cellulase under solid-state conditions by an actinobacterium, Streptomyces enissocaesilis DQ026641. The upsurge production of cellulase was optimized manually regulating important process variables such as substrate (particle size, moisture content), organism (inoculum size), physicochemical attributes (pH, temperature) and mineral salts (NaCl, MgSO 4 , FeSO 4) following one factor at a time approach. The maximum production (71.10 IU/ml) of cellulase was obtained at particle size 2 mm, moisture content 1.25%, temperature 45°C, inoculum size 1 × 10 8 and NaCl 1.5%. Enhanced production (79 IU/ml) of cellulase was achieved by following Response Surface Methodology with Centre Composite Design, considering pH 6.5, temperature 45°C and sodium chloride 1.5% as critical process variables. The quadratic impact of pH, temperature and sodium chloride significantly contributed for the production of cellulase under solid-state conditions from maize stover mediated by S. enissocaesilis DQ026641.
