Biotechnological tools engaged in the bioremediation process are in reality, sophisticated and dynamic in character. For specialized reasons, a broad variety of such devices are employed to produce a safe and balanced environment free of all types of toxins and so make life simpler for humans on planet Earth. Actinomycetes is one of these extremely important and functionally helpful groups. They can be used for a variety of bioremediation objectives, including biotransformation, biodegradation, and many more. Actinomycetes are one of the most varied groups of filamentous bacteria, capable of prospering in a variety of ecological settings because to their bioactive capabilities. They’re famous for their metabolic diversity, which includes the synthesis of commercially useful primary and secondary metabolites. They produce a range of enzymes capable of totally destroying all of the constituents. They are well-known for their ability to produce bioactive secondary metabolites. Members of various genera of Actinomycetes show promise for application in the bioconversion of underutilized urban and agricultural waste into high-value chemical compounds. The most potential source is a wide range of important enzymes, some of which are synthesized on an industrial scale, but there are many more that have yet to be discovered. Bioremediation methods, which use naturally existing microbes to clear residues and contaminated regions of dangerous organic chemicals, are improving all the time. In the realm of biotechnological science, the potential of actinomycetes for bioremediation and the synthesis of secondary metabolites has opened up intriguing prospects for a sustainable environment.

With the advent of green pharmaceuticals, the secondary metabolites derived from plants have provided numerous leads for the development of a wide range of therapeutic drugs; however the discovery of new drugs with novel structures has declined in the past few years. Cryptogams including lichens, bryophytes, and pteridophytes represent a group of small terrestrial plants that remain relatively untouched in the drug discovery process though some have been used as ethnomedicines by various tribes worldwide. Studies of their secondary metabolites are recent but reveal unique secondary metabolites which are not synthesized by higher plants. These compounds can have the potential to develop more potential herbal drugs for prevention and treatment of diseases The present article . deals with the secondary metabolites and pharmacological activities of cryptogams with an objective to bring them forth as potential source of biodynamic compounds of therapeutic value.

The species Dracaena and Sansevieria, that are well-known for different uses in traditional medicines and as indoor ornamental plants with air purifying property, are rich sources of bioactive secondary metabolites. In fact, a wide variety of phytochemical constituents have been isolated so far from about seventeen species. This paper has reviewed the literature of about 180 steroidal saponins, isolated from Dracaena and Sansevieria species, as a basis for further studies. Saponins are among the most characteristic metabolites isolated from the two genera. They show a great variety in structural motifs and a wide range of biological activities, including anti-inflammatory, anti-microbial, anti-proliferative effects and, in most case, remarkable cytotoxic properties.

The function of secondary metabolites has been a subject of debate since the first isolation and characterization of these often times structurally complex chemical compounds. By definition, secondary metabolites are naturally produced compounds that are not essential for the survival of the producing organism, as opposed to primary metabolites. Bioassays have revealed a wide range of biological activities, such as cytotoxicity, ichthyotoxicity, antimicrobial and antifeedant activity, antifoulant and anti-cancer activities. However, some of these activities are manifested against organisms that do not represent logical targets, since they would never be encountered by the producing organism in their natural habitat.

Medical Importance

The actinomycetes are Gram-positive bacteria belonging to the order Actinomycetales within the phylum Actinobacteria . They include members with significant economic and medical importance, for example filamentous actinomycetes such as Streptomyces species, which have a propensity to produce a plethora of bioactive secondary metabolites and form symbioses with higher organisms, such as plants and insects. Studying these bacteria is challenging, but also fascinating and very rewarding. As a Microbiology Society initiative, members of the actinomycete research community have been developing a Wikipedia-style resource, called ActinoBase, the purpose of which is to aid in the study of these filamentous bacteria. This review will highlight 10 publications from 2019 that have been of special interest to the ActinoBase community, covering 4 major components of actinomycete research: (i) development and regulation; (ii) specialized metabolites; (iii) ecology and host interactions; and (iv) technology and methodology.

The main goal of the research was to explore the existence of phytochemicals, quantification of primary and secondary metabolites of leaves extract of Artabotrys hexapetalus  (L.f.) Bhandari. The phytochemical activity of leaves of Artabotrys hexapetalus was assessed using different solvent extracts like water, ethanol, acetone, chloroform and petroleum ether. Among the different solvent extracts, aqueous leaves extract revealed the high content of phytochemicals. So the aqueous leaves extract was used for further investigations. Aqueous leaves extract of Artabotrys hexapetalus was subjected to quantitative analysis of primary metabolites like carbohydrates, proteins and amino acids. Quantitative analysis of secondary metabolites like flavonoids, tannins and phenols were performed using aqueous leaves extract of Artabotrys hexapetalus. Qualitative screening of phytochemicals reported the existence of carbohydrates, amino acids, proteins, flavonoids, alkaloids, saponins, phenols, glycosides, tannins and diterpenes. Quantitative analysis showed the presence of carbohydrates (43.16±1.0 mg/g extract), proteins (60.4±0.88 mg/g extract), amino acids (19.33 ± 1.30 mg/g extract), flavonoids (28.3 ±0.91 mg/g extract), tannins (24.53±1.02 mg/g extract) and phenols (7.63±0.85 mg/g extract). The present study concluded that aqueous leaves extract of Artabotrys hexapetalus as a potential source of phytochemicals, primary and secondary metabolites.
