Trentepohlia umbrinaPurposeThe colonisation of building material by photosynthetic organisms is highly dependent on the environmental conditions and the nature of the substrate. The growths of red-orange phototrophic biofilms have been widely reported in the literature and have commonly been associated ...
Hérisset (1946) placed on mineral agar spores of Arthonia, Graphis, and Opegrapha in contact with the free-living alga Trentepohlia umbrina and noted lichenized contacts between the hyphae and algal filaments after 3 weeks. Algal cells surrounded by hyphae contained less β-carotene, indicating...

The aim of the study is to examine in vitro antioxidant and antimicrobial activities of the methanol extract of the green microalga Trentepohlia umbrina. Antioxidant activity was evaluated by five different methods: free radical scavenging, superoxide anion radical scavenging, reducing power, ...
cf. umbrina occurred on stone walls; and P. lagenifera grew on several substrata, mainly cement and asbestos sheeting. T. aurea and T. iolithus were found on old concrete and cement walls; in particular, the latter species formed characteristic, extensive, deep-red patches on many buildings...
umbrina. The record of Trentepohlia aurea, based on some specimens deposited in BISH, is rejected. Growth and reproduction of some entities (P. bosseae var. samoensis, P. effusa, P. lagenifera and T. arborum) were examined in culture. In the Hawaiian Islands these algae grow primarily...
umbrina; no filamentous fungi were detected here. The black colour was produced by dense, amorphous pigment deposits in the colony centres. Insolation levels were high (400 渭mphotons m 2 s 1) and the moisture content of the stone was 0.7%. The high carotenoid:chlorophyll- 伪 ratio of ...
