Bromoperoxidase activity was detected in the marine green macro-alga, Ulvella lens, which is used to induce the larval metamorphosis of sea urchin in aquaculture in Japan. The enzyme activity was enhanced 8.5- and 2.2-fold by the addition of cobalt and vanadium ions to the reaction mixture, respectively. The volatile halogenated compounds dibromomethane and tribromomethane were formed in the reaction mixture when the enzyme was incubated with oxaloacetate, hydrogen peroxide and potassium bromide. These results suggest that dibromomethane, which was reported to be released by U. lens and play an important role as the inducer of larval settlement and metamorphosis, is produced by bromoperoxidase in the alga.

Methane was converted to light olefins (ethene and propene) or higher hydrocarbons in a continuous flow reactor below 375 °C over H-SAPO-34 catalyst via an in situ halogenation (chlorination/bromination) protocol. The reaction conditions can be efficiently tuned toward selective monohalogenation of methane to methyl halides or their in situ oligomerization to higher hydrocarbons. The presence of C5+ hydrocarbons in the reaction products clearly indicates that by using a properly engineered catalyst under optimized reaction conditions, hydrocarbons in the gasoline range can be produced. This approach has significant potential for feasible application in natural gas refining to gasoline and materials under moderate operational conditions.
