Publisher's announcement

ENZYME AND MICROBIAL TECHNOLOGY to go bimonthly

We are pleased to announce an increase in frequency for ENZYME AND MICROBIAL TECHNOLOGY, from quarterly to bimonthly publication, from January 1982. Since its successful launch in January 1979, the interest shown in the journal together with the growth in the level of submissions has led to our decision to publish bimonthly. The important reviews and significant advances in research contained in ENZYME AND MICROBIAL TECHNOLOGY will now be available to our readers six times a year.
