“…However, as an indication that this may indeed occur it has been shown by Kokke (1970) that the proportion of DDT-resistant bacteria is markedly elevated in DDT-containing environments. Cyclodiene insecticide-resistant Gram-positive strains do exist as illustrated by the reported contamination of aldrin samples by Bacillus cereus and Bacillus subtilis (Fletcher & Bollen, 1954).…”

The growth of a range of Gram-positive bacteria was inhibited by organochlorine insecticides while that of Gram-negative organisms was unaffected. Growing cultures of Bacillus subtilis (ATCC 9372) treated with 20 p.p.m. technical chlordane ceased to grow and showed a decline in viable count and respiration rate, both being eliminated after about 3 h. A delayed release of incorporated ~-[U-l*C]leucine and L-malate dehydrogenase occurred concomitant with a fall of It is suggested that these phenomena are a result of disruption of membraneassociated metabolism, including electron transport and cell wall biosynthesis, which leads to cell lysis. No effect on these parameters occurred with growing cultures of Escherichia coli (ATCC 8739). The chlordane sensitivity of succinate oxidation by sphaeroplasts of E. coli indicates that the intact cell wall prevents penetration of pesticide to sensitive sites within the walls of Gram-negative bacteria.

“…Accumulation of insecticides by microbes in soil and from solutions was demonstrated by HENZELL and LANCASTER (1969), KALLMAN and ANDREWS (1963), KOKKE (1970), and UEYAMA et al (1971). They showed that fungal and bacterial cells from enrichment cultures accumulated DDT, BHC, malathion and carbaryl from culture medium and partially converted them.…”

“…ALBO~E et al (1972) found that technical DDT at 100 ppm in agar consistently reduced counts of both aerobic and anaerobic bacteria cultured from a mud. KOKKE (1970) showed that DDT in culture agar at 0.1 ppm inhibited bacteria from ditch water and nursery soil. Ko and LOCKWOOD (1968) also demonstrated an inhibitory effect of DDT at 10 ppm on certain microorganisms.…”

“…Pure microbial cultures were isolated by the autoradiographic technique described by GROSSBARD (1970) and KOKKE (1970). The agar media were similar to the media used in the enrichment except that they contained per litre 15 g agar and that 14 C-labelled chlorthiamid (Shell, Sittingbourne England, specific activity 9.7 /tCi/mg and purity 99.5 %) was substituted for 10 % of the total herbicide.…”

The herbicides chlorthiamid and dichlobenil inhibited the growth of some actinomycetes in starch-casein medium. The effect of these herbicides on the other bacteria tested was insignificant. Chlorthiamid and dichlobenil arc slowly degradable herbicides. Bacteria such as Arthrobacter, unidentified coryneforms and Bacillus could degrade the herbicides by cometabolism. 2,6-Dichlorobenzamide, 2,6-dichlorobenzoic acid, carbon dioxide, chloride, a catechol compound and many unidentified compounds were found as metabolites. Arthrobacter strains capable for dechlorination could also cleave the aromatic ring, both processes occurring in aerated cultures. More than half of the chloride was liberated in three weeks at 28°C by the most active Arthrobacter strain.
