AB  - Duckweed (L. minor) is a cosmopolitan aquatic plant of simplified morphology and rapid vegetative reproduction. In this study, an H. paralvei bacterial strain and its influence on the antioxida-tive response of the duckweeds to phenol, a recalcitrant environmental pollutant, were investigated. Sterile duckweed cultures were inoculated with H. paralvei in vitro and cultivated in the presence or absence of phenol (500 mg L−1 ), in order to investigate bacterial effects on plant oxidative stress during 5 days. Total soluble proteins, guaiacol peroxidase expression, concentration of hydrogen peroxide and malondialdehyde as well as the total ascorbic acid of the plants were monitored. Moreover, bacterial production of indole-3-acetic acid (IAA) was measured in order to investigate H. paralvei’s influence on plant growth. In general, the addition of phenol elevated all biochemical parameters in L. minor except AsA and total soluble proteins. Phenol as well as bacteria influenced the expression of guaiacol peroxidase. Different isoforms were associated with phenol compared to isoforms expressed in phenol-free medium. Considering that duckweeds showed increased antioxidative parameters in the presence of phenol, it can be assumed that the measured parameters might be involved in the plant’s defense system. H. paralvei is an IAA producer and its presence in the rhizosphere of duckweeds decreased the oxidative stress of the plants, which can be taken as evidence that this bacterial strain acts protectively on the plants during phenol exposure.

AB  - The antimicrobial activity of methanol extracts of three thalloid liver­worts, Marchantia polymorpha, Conocephalum conicum and Pellia endiviifolia and bis-bibenzyl marchantin A, the most dominant compound in the methanol extract of M. polymorpha, have been investigated in this research. 1H-NMR spec­troscopy revealed that the M. polymorpha and P. endiviifolia extracts of liverwort contain terpenes, oils, sugars and bis-bibenzyls, while these specific macrocyclic compounds were absent in the C. conicum extract. The anti­mic­robial potential was tested on eight bacterial strains. Antimicrobial effects of extracts and mar­chantin A were observed against Gram-positive bacteria, while they showed no effect against Gram-negative bacteria in both methods used – well diffusion and broth microdilution.
AB  - У овом раду испитиван је хемијски састав и антибактеријска активност метанолних екстраката три јетрењачe, Marchantia polymorpha, Conocephalum conicum и Pellia endiveifolia и бис-бибензила маршанцина A, доминантне компоненте у метанолном екстракту M. polymorpha. 1H-NMR спектроскопија је показала присуство терпена, уља, шећера и бис-бибензила у екстрактима M. polymorpha и P. endiviifolia, док екстракт C. conicum не садржи специфична макроциклична једињења – бис-бибензиле. Антимикробни потен- цијал је тестиран на осам бактеријских сојева. Антимикробни ефекат маршанцина А уочен је на све грам позитивне сојеве, док је ефекат изостао код грам негативних сојева у обе тестиране методе – дифузионе методе у бунарима и микродилуционе методе у хранљивом бујону.
