Sequences from aerobic, anaerobic, psychrophilic, thermophilic, halophilic, alkaliphilic, acidophilic, desiccation-resistant, autotrophic, and heterotrophic organisms were present, including a number from multicellular eukaryotes.
Saprophytes are a plant, fungus, or micro-organism, more accurately called myco-heterotrophs because they actually parasitize fungi, rather than dead organic matter directly.
