This study aimed to isolate bacteria that coexist with the edible mushroom Grifola frondosa when it is cultured on wood, and to determine their interactions; in turn, the aim was to find bacteria that stimulate mycelial growth so as to decrease the time required for spawn preparation on potato dextrose agar (PDA). Some Pseudomonas, Dyella, Bacillus, and Priestia spp. isolated from the cultivation surroundings of G. frondosa had a positive effect on the mycelial growth of the fungus in PDA. However, some isolated bacteria had a severe negative effect on the mycelial growth, especially Burkholderia spp. Thus, both mycelial-promoting bacteria and potentially pathogenic bacteria coexist with G. frondosa in cultivation. Enzyme activity assays indicated that some wood-degrading bacteria inhabit the cultivation surroundings of G. frondosa, and these bacteria probably help the fungus to degrade wood (especially cellulose).

Terminalia bellerica is well-known for producing edible fruits with pharmacotherapeutic properties. Traditional healers use these species to treat and control diabetes mellitus, its side effects, and other illnesses. Involved in this disease's pathophysiological process, extensive research has been conducted to validate and comprehend these bioactive claims scientifically. This research aims to ascertain the bioactive metabolite contents of different solvent polarities, including ethyl acetate, hexane, distilled water, and methanol. The phenol concentration was determined using the Follin-Ciocalteu procedure to be between 23.45 and 160.41 mg GAE/g. The aluminum chloride colorimetric technique measured flavonoid concentration from 88.52 to 7.12 mg QE/g. The quantitative values of tannic acid, which spanned from 0.78 to 5.32 mg TAE/g, were determined by spectrophotometry UV-VIS. The extracts' capacity to reduce free radical damage ABTS (2, 2' azinobis (3-ethylbenzene-thiazoline-6-sulfonic-acid) and DPPH (2,2-diphenyl-1-picrylhydrazyl) was examined. The extract ethyl acetate exhibited the most significant level of antioxidant activity, with IC50 values for DPPH and ABTS of 28.17 and 22.22 g/ml, respectively. Staphylococcus aureus (23 mm) and were tested for antibacterial and antifungal activity in a methanol extract (21 mm). In vitro, antidiabetic activities were assessed using α-glucoside and α-amylase inhibition. The ethyl acetate extract has α-glucoside inhibition IC50 of 23.04 g/ml and α-amylase inhibition IC50 of 25.35 g/ml. T. bellerica seed includes secondary metabolites that show promise as lead chemicals in creating potent medications.

Plants have various bioactive compounds that have pharmacological activity. Kedawung (Parkia timoriana (DC) Merr) is an indigenous plant in Indonesia that contains bioactive compounds. The leaves, bark, seeds, and roots of P. timoriana are commonly used in traditional medicine. The purpose of this study was to determine the chemical composition of P. timoriana bark extract and to assess its antioxidant, antidiabetic, and antibacterial activity. The bark of P. timoriana was extracted with various solvents that differ in polarity, such as water, methanol, ethyl acetate, and hexane. All extracts were investigated for antioxidant activities by 2,2-diphenyl-1-picrylhydrazyl) (DPPH) free-radical and 2,2’-azinobis (3-ethylbenz-thiazoline-6-sulfonic-acid) (ABTS) scavenging ability. The in-vitro antidiabetic activity was carried out by α-amylase and α-glucosidase inhibition. Antibacterial and antifungal activities were determined by the agar disc diffusion method. Parkia timoriana bark extracts contained alkaloids, flavonoids, steroids, tannins, terpenoids, saponins, reducing sugars, and cardiac glycosides. The ethyl acetate extract possessed the highest total phenolics, alkaloids, flavonoids, saponins, tannic acid, and terpenoids. Secondary metabolites in all extracts contributed to free radical scavenging, antidiabetic, antibacterial, and antifungal properties. The P. timoriana bark contains natural chemical compounds that might be useful as therapeutic agents for producing bioactive products and pharmaceuticals in the future.

Biotransformation of dichlorodiphenyltrichloroethane by white-rot fungus Ganoderma lingzhi Reviewed

Dichlorodiphenyltrichloroethane (DDT) is one of the persistent organic pollutants (POPs) extensively used in the 1940s for pest control and some diseases such as malaria and dengue. Although, since the 1990s the use of DDT has been restricted in Indonesia, the residue of DDT persists in the environment and has a negative impact on animals and humans. In this study, DDT was metabolized with the white-rot fungus Ganoderma lingzhi. DDT was degraded approximately 53% by G. lingzhi in potato dextrose broth (PDB) medium for 7 d incubation. The metabolites were identified by using gas chromatography/mass spectrometry (GC/MS). This fungus transformed DDT to at least two metabolites, namely DDE (1,1-dichloro-2,2-bis (4-chlorophenyl) ethylene) and DDD (1,1-dichloro-2,2-bis (4-chlorophenyl) ethane). The results indicated that G. lingzhi has a potential ability to degrade DDT in the environment.
