Paddy straw (PS) and pine needles (PN) are one of the challenging biomasses in terms of disposal and compost making due to their high silica and tannin contents. Particulate air pollution, loss of biodiversity and respiratory impairments are some of disastrous outcomes caused by burning. However, high percentage of cellulose and hemicellulose makes them potential substrate for paper and pulp industries. The main aim of work was to study and utilize a combinatorial approach of weak chemical treatment and lignin degrading fungal species as agents of effective production of lignin modifying enzymes (LME's) for lignin depolymerisation from the biomasses. Phanerochaete chrysosporium was found to be the best degrader of lignin (47.11 % in PS + PN in 28 days) with maximum LME's production between 10th-17th days. Efficient lignin degradation in the PS and PN biomass will aid further application in pulp production supporting the transition to a circular economy in a greener way.

As concern for environmental sustainability continues to grow, wood, as a renewable resource and a composite of natural polymers (cellulose, hemicellulose, and lignin), has garnered increasing research attention. Traditional wood may have certain limitations in specific applications, such as being susceptible to moisture and biological degradation, as well as shortcomings in strength and durability. Therefore, wood modification has become a crucial strategy to enhance its performance and broaden its range of applications.

The timing of microbial inoculation is a decisive factor influencing both the efficiency and quality of green waste (GW) composting. This study evaluated the effects of applying a self-developed lignocellulose-degrading compound microbial inoculum at different composting phases (mesophilic, thermophilic, and cooling) compared to a commercial Effective Microorganisms agent. Thermophilic-phase inoculation (T2) was most effective by enhancing the complementary metabolic functions between strains, thus establishing an efficient lignocellulose degradation system.

The turnover of dissolved organic matter (DOM) in soil regulated by biodegradable microplastics (MPs) has garnered much attention due to its profound impact on the storage and stability of soil organic matter. However, the transformation and reactivity of plant-derived and microbially derived DOM by microorganisms adapted to biodegradable MPs, and the involved microbial physiological processes, remain nearly unknown. Here, we added virgin and aged polylactic acid (PLA) and polyhydroxyalkanoate (PHA) to agricultural soils and incubated for 56 days.

In this paper, lignin was chemically extracted from fibers and modified with branched polyethyleneimine (BPEI) and the resulting samples were applied for the adsorption of two anionic dyes; Acid red 183 (AR183) and Acid blue 25 (AB25) from aqueous suspension. Analytical characterization methods including SEM, FT-IR, TGA/DTG, and XRD were used to analyze the studied samples. The images of the extracted lignin displayed a rough feature.

Microbial agents represent a valuable class of additives that can enhance the value and effectiveness of compost products. This paper provides a comprehensive review of the mechanisms and applications of microorganisms in regulating lignocellulose degradation, controlling gas emissions, and managing typical pollutants during the composting of organic solid wastes. Inoculation with microbial agents can significantly improve the degradation efficiency, quality, and environmental friendliness of compost.
