Structural Modification of Trans-Cinnamic Acid Using Colletotrichum Acutatum
Rev. Fac. Ing. Univ. Antioquia N.° 63 pp. 20-29.

Calle 64 x Carrera 65 Autopista Norte. AA 3840. Medellín, Colombia. (Recibido el 18 de febrero de 2011. Aceptado el 23 de mayo de 2012) Abstract The biotransformation of trans-cinnamic acid by whole cells of the Colombian native phytopathogenic fungus Colletotrichum acutatum was studied. Initially, fungitoxicity of this compound against C. acutatum was evaluated; trans-cinnamic acid exhibited a moderate to weak toxicity against the microorganism and apparently a detoxification mechanism was present. Then, in order to study such mechanism and explore the capacity of this fungus to biotransform trans-cinnamic acid into value-added products, the microorganism was incubated with the substrate using three different culture media (Czapeck-Dox, Sabouraud and PDB) at room conditions. Using Czapeck-Dox medium, whole cultures of C. acutatum reduced trans-cinnamic acid, first to aldehydes (trans-cinnamaldehyde and 3-phenylpropanal), then to alcohols (cinnamyl alcohol and 3-phenyl-1-propanol). Subsequently, these alcohols were transformed to the corresponding acetyl esters. Nevertheless, some of these products were absent or present at different concentration when culture medium was changed. -

Functional Expression of a Novel Methanol-Stable Esterase From
Cai et al. BMC Biotechnology (2020) 20:36 https://doi.org/10.1186/s12896-020-00622-1 RESEARCH ARTICLE Open Access Functional expression of a novel methanol- stable esterase from Geobacillus subterraneus DSM13552 for biocatalytic synthesis of cinnamyl acetate in a solvent- free system Xianghai Cai1†, Lin Lin2,3†, Yaling Shen1, Wei Wei1* and Dong-zhi Wei1 Abstract Background: Esterases are widely distributed in nature and have important applications in medical, industrial and physiological. Recently, the increased demand for flavor esters has prompted the search of catalysts like lipases and esterases. Esterases from thermophiles also show thermal stability at elevated temperatures and have become enzymes of special interest in biotechnological applications. Although most of esterases catalyzed reactions are carried out in toxic and inflammable organic solvents, the solvent-free system owning many advantages such as low cost and easy downstream processing. Results: The gene estGSU753 from Geobacillus subterraneus DSM13552 was cloned, sequenced and overexpressed into Escherichia coli BL21 (DE3). The novel gene has an open reading frame of 753 bp and encodes 250-amino-acid esterase (EstGSU753). The sequence analysis showed that the protein contains a catalytic triad formed by Ser97, Asp196 and His226, and the Ser of the active site is located in the conserved motif Gly95-X-Ser97-X-Gly99 included in most esterases and lipases. The protein catalyzed the hydrolysis of pNP-esters of different acyl chain lengths, and the enzyme specific activity was 70 U/mg with the optimum substrate pNP-caprylate. The optimum pH and temperature of the recombinant enzyme were 8.0 and 60 °C respectively. -

The Reactions of Silicomolybdic Acid with Organic Compounds 1 John H. Billman, Donald B. Borders, and John A. Buehler, Indiana University, Hondo AFB, Texas, and Anderson College For many years the analytical and inorganic chemists have been seeking specific reagents to identify metallic ions. At the same time, the organic chemist has been interested in finding compounds that would be useful for spotting different types of functional groups commonly en- countered in organic compounds. A typical example of such a reagent is ferric chloride, which has found wide use with phenols. For several years we have been testing various compounds in an effort to find reagents that would be specific for metallic ions as well as organic functional groups. In the course of our investigation it was found that silicomolybdic acid (1), H 4 SiMo 12 O 40 .xH 2 O, would produce a dark blue mixture in the presence of aliphatic aldehydes, but would not give the same test with aromatic aldehydes. Further investigation indi- cated that only aldehydes that contain a hydrogen atom on the alpha carbon atom would give a positive test. On the basis of this work a more thorough study was undertaken of the reaction of silicomolybdic acid with various organic compounds containing different functional groups. Altogether the reagent has been tried with a one-hundred and forty-five organic compounds. Table 1 shows the aldehydes that have been tested.

molecules Review Effects of Cinnamon (Cinnamomum spp.) in Dentistry: A Review Spartak Yanakiev Medical College Y. Filaretova, Medical University—Sofia, Yordanka Filaretova Street 3, 1000 Sofia, Bulgaria; [email protected]fia.bg; Tel.: +35-98-8644-5108 Received: 26 July 2020; Accepted: 11 September 2020; Published: 12 September 2020 Abstract: Dental medicine is one of the fields of medicine where the most common pathologies are of bacterial and fungal origins. This review is mainly focused on the antimicrobial effects of cinnamon essential oil (EO), cinnamon extracts, and pure compounds against different oral pathogens and the oral biofilm and the possible effects on soft mouth tissue. Basic information is provided about cinnamon, as is a review of its antimicrobial properties against the most common microorganisms causing dental caries, endodontic and periodontal lesions, and candidiasis. Cinnamon EO, cinnamon extracts, and pure compounds show significant antimicrobial activities against oral pathogens and could be beneficial in caries and periodontal disease prevention, endodontics, and candidiasis treatment. Keywords: cinnamon essential oil; dentistry; oral pathogens; oral biofilm; candida; antimicrobial effect; dental caries; endopathogens; cinnamaldehyde; eugenol 1. Introduction Dental medicine is one of the fields of medicine where the most common pathologies are of bacterial and fungal origins. Widely spread diseases like dental caries, periodontal disease, and endodontic lesions are caused by well-known bacterial and fungal pathogens: Streptococcus mutans, Streptococcus salivarius, Streptococcus sanguinis, Porfiromonas gingivalis, Prevotella intermedia, Actinobacilus actinomycetemcomitans, Enterococcus faecalis, Candida albicans, etc. [1]. Preventive medicine relies mostly upon reducing the bacterial biofilm via oral hygiene. The most often used active ingredients in mouth rinses and toothpastes are chlorhexidine, hyaluronic acid, and fluorides.
