“…The petroleum hydrocarbon mineralization ability of fungi and plants was investigated by Ani et al (2021), and the results confirmed that different rates of hydrocarbon degradation by isolated fungi were observed. An in vitro biodegradation study showed that Aspergillus niger, Fusarium solani, Curvularia lunata, and Trichoderma harzianum were the most effective in degrading kerosene (78%), diesel (70%), spent engine oil (83%), and crude oil (77%), respectively (Ani et al, 2021). Kristanti et al (2011) investigated microbial decomposition of crude oil-contaminated soil using the white rot fungal species Polyporus sp.…”

Petroleum hydrocarbons (PHCs) are key energy sources for several industries and daily life. Soil contamination from oily PHC spills is commonly detected in cities and industrial facilities where crude oil is used. The release of PHC pollutants into the environment, whether accidentally from petroleum industries or human activities, has become a leading source of soil pollution. Consequently, the mineralization of PHC-polluted sites has become a central issue worldwide. Although bioremediation is imperative for environmental safety and management, several approaches have been developed for PHC bioremediation. However, much remains to be explored in this regard. This review explores bioremediation of PHC-contaminated soil and provides a comprehensive examination of the principles, degradation mechanisms, and recent advancements in the field. Several microbial species have been used to study the bioremediation of PHCs, emphasizing the pivotal roles of diverse microbial communities. Aspergillus spp., Proteobacteria, and Firmicutes groups of microorganisms were the most efficient in remediating PHC-contaminated soil. The fundamental concepts behind the bioremediation of PHC and the complex mechanisms that govern degradation were elucidated. Limiting factors in the bioremediation process and recent innovations propelling the field were also discussed. Therefore, understanding the degradation pathway, ensuring complete degradation of contaminants, and flexible legislation for the proper use of genetically engineered microbes can make bioremediation more sustainable and cost-effective.

“…No tendril anatomical data were found about Luffa aegyptiaca . However, the species was used against hydrocarbon-contaminated soil through rhizoremediation, and chemical analysis of this species was also carried out in research papers [ 25 ]. In Western Africa, three genera of the Cucurbitaceae family, e.g., Momordica , Luffa, and Trichosanthes, were studied for their foliar epidermis and tendril morphology.…”

This research examined the histological micro-structure of tendril vasculature in cucurbitaceous taxa. In this research, the tendril anatomy of 17 taxa of Cucurbitaceae categorized into seven genera, including Cucumis (five species), Cucurbita and Luffa (three species each), Citrullus and Momordica (two species each) while Lagenaria and Praecitrullus (one species each), collected from different areas of the Thal desert were examined via microscopic imaging to explore its taxonomic significance. Tendril transverse sections were cut with a Shandon Microtome to prepare slides. The distinctive characteristics of taxonomic value (qualitative and quantitative) include tendril and vascular bundle shape, variation in the number of vascular bundles, tendril diameter length, layers of sclerenchyma, and shape of collenchyma and epidermal cells. Tendril shapes observed are irregular, slightly oval-shaped, slightly C shaped, angular (4-angled, 6-angled, or polygonal), and star shaped. Quantitative measurements were taken to analyze the data statistically using SPSS software. Cucurbita pepo had a maximum tendril diameter length of 656.1 µm and a minimum in Momordica balsamina of 123.05 µm. The highest number of vascular bundles (12) were noticed in Luffa acutangula var.amara. Angular type was prominent in collenchyma, and irregular shape was dominant in sclerenchyma cells. A maximum of seven to nine sclerenchyma layers were present in Lagenaria siceraria and a minimum of two or three layers in Cucumis melo subsp. agrestis, Cucumis melo var. flexuosus, and Cucumis melo var.cantalupensis. Epidermis cells also show great variations with a rectangular shape being dominant. Statistical UPGMA dendrogram clustering of tendril vasculature traits shows that histological sections studied with microscopic techniques can be used to identify species and will play a vital role in future taxonomic and phylogenic linkages.

“…It is also observed that when treatment is given with both plant and fungus, the degradation rate increases as compared to single inoculation. So, this study concludes that C. lunata increases the germination, growth, survival, and bioremediation efficacy of Luffa aegyptiaca in a polluted environment (Ani et al, 2021). Cochliobolus lunatus strain CHR4D now known as Curvularia lunata, has been predicted as a potential candidate for mycoremediation of high molecular weight polycyclic aromatic hydrocarbon polluted environments because it shows rapid degradation of chrysene, which is a four-ringed high molecular weight (HMW) polycyclic aromatic hydrocarbon (PAH) (Bhatt et al, 2014).…”

“…Rhizoremediation studies with fungal genera associated with Luffa aegyptiaca (Mill.) suggest that Curvularia lunata have a higher capacity to degrade spent engine oil in contaminated soil with the efficiency of 83% (Ani et al, 2021 ). It is also observed that when treatment is given with both plant and fungus, the degradation rate increases as compared to single inoculation.…”

Many filamentous fungi are known to produce several secondary metabolites or bioactive compounds during their growth and reproduction with sort of various biological activities. Genus Curvularia (Pleosporaceae) is a dematiaceous filamentous fungus that exhibits a facultative pathogenic and endophytic lifestyle. It contains ~213 species among which Curvularia lunata, C. geniculata, C. clavata, C. pallescens, and C. andropogonis are well-known. Among them, C. lunata is a major pathogenic species of various economical important crops especially cereals of tropical regions while other species like C. geniculata is of endophytic nature with numerous bioactive compounds. Curvularia species contain several diverse groups of secondary metabolites including alkaloids, terpenes, polyketides, and quinones. Which possess various biological activities including anti-cancer, anti-inflammatory, anti-microbial, anti-oxidant, and phytotoxicity. Several genes and gene factors are involved to carry and regulate the expression of these activities which are influenced by environmental signals. Some species of Curvularia also show negative impacts on humans and animals. Apart from their negative effects, there are some beneficial implications like production of enzymes of industrial value, bioherbicides, and source of nanoparticles is reported. Many researchers are working on these aspects all over the world but there is no review in literature which provides significant understanding about these all aspects. Thus, this review will provide significant information about secondary metabolic diversity, their biological activities and biotechnological implications of Curvularia species.
