“…Belmares et al (2004) stated that plants and microbes can produce tannases. Tannase plays a role in the ability of pathogens to cause symptoms of plant diseases (Sharma, 2019). Therefore, the pectinase and tannase enzymes in the red pigment produced by the Java isolate C. acutatum also play a role in causing symptoms of anthracnose disease in red chilies.…”

Abstract. Muljowati JS, Soesanto L, Nugroho LH. 2021. Short Communication: Histopathology of red chilli fruit (Capsicum annuum) infected with Colletotrichum acutatum of Java, Indonesia isolates. Biodiversitas 22: 874-880. Colletotrichum acutatum isolates from Malang, Temanggung, Kulonprogo, Brebes, Garut, and Pandeglang in Indonesia varied in their ability to produce pigments. In the present study, the histopathological status of red chilli was investigated during the early phase of infection by C. acutatum Java isolate. The results included a description of the histopathological features of red chillies (Capsicum annuum) in the early phase of infection by C. acutatum isolates and the relationship between the origin of the isolates and the time of onset of infection. The red chilli fruits were inoculated with fungal conidia suspension and then the histopathology of chilli fruits was observed at 0 hours (uninfected control), 8 hours, 16 hours, 24 hours, and 32 hours after inoculation. The results showed that C. acutatum isolates from Kulonprogo caused host damage within 8 hours, while the other isolates (from Malang, Brebes, Garut and Pandeglang) began to produce similar symptoms at 16 hours or 24 hours. This study revealed for the first time that pathogenic activity begins at the onset of infection, and the resulting anatomical damage to red chillies begins at different times.

“…Among the phenolic compounds, the presence of tannins in hydrophilic extract was identified in the internal and external regions of E. grandis wood (Figure 4). Tannins represent the fourth most abundant group of secondary metabolites after cellulose, hemicellulose and lignins and are characterized as defensive molecules of the plant, having as main advantage their phenolic structure and antioxidant action (Sharma, 2019;Research, Society and Development, v. 9, n. 11, e94591110537, 2020 (CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi.org/10.33448/rsd-v9i11.10537 Shirmohammadli et al, 2018). Mamani et al (2012) revealed that tannins act defensively and confer resistance against pathogens in different plant species.…”

This work aimed to investigate phytochemical prospection in treated and untreated wood of Eucalyptus grandis to understand the dynamics of extractives in relation to heat treatment. Samples of E. grandis wood were collected and grouped into external and internal regions. Half of the samples from each region were submitted to heat treatment at 190 ºC. From the treated and untreated samples, phytochemical tests were performed to detect classes of metabolites present in the E. grandis raw wood, hydrophilic extract and lipophilic extract. Phytochemical analysis detected the presence of alkaloids, phenolic compounds and triterpenoids in all hydrophilic extracts of the studied species. Presence of flavanonols, flavanones and saponins was detected only in the internal region of the wood. Tannins, leucoanthocyanidins, triterpenoids and saponins were influenced by heat treatment. The classes of flavonoids, xanthones and alkaloids are the most resistant to heat treatment. The phytochemical analysis made it possible to identify a new class of extractives that emerged after heat treatment, flavones.

“…To overcome the limitations of tannic acid conversion by physical–chemical treatment [12] , [13] , [14] , the use of enzymes has been reported as an alternative for wastewater and effluents [16] , [17] , [18] . The main enzymatic routes described in the literature suggest the use of Aspergillus and Penicillium strains [16] , [17] , [18] . When in contact with tannic acid, these microorganisms produce the tannase enzyme (tannin-acyl-hydrolase).…”

“…When in contact with tannic acid, these microorganisms produce the tannase enzyme (tannin-acyl-hydrolase). This enzyme hydrolyzes the ester group generating glucose and gallic acid as main products [16] , [17] , [18] . Although tannase enables efficient conversion of tannic acid (higher than 95% in up to 21 days), its action is inhibited by the presence of metals ( e.g., Cu, Zn, Fe, Mn, and Mg).…”

Additionally, tannase can be inhibited when in contact with sulfate and chloride species, decreasing the applicability of this route for wastewater treatment [16] , [17] , [18] .…”
